Storing donated human tissue demands specialized solutions. Facilities must balance high-density capacity, strict environmental controls, and robust protection against incidental moisture. This guide explores the design process for a safe, efficient biological storage system, using a real-world case study from New Horizon, a tissue bank that partnered with Labs USA and Metro. The core challenges were to maximize storage density, mitigate water risks, and ensure the system could be relocated in the future.
Project Requirements and Risk Profile
The project began with a clear set of requirements to address current storage challenges and future operational needs. Each requirement was tied to a specific risk, from sample damage to inefficient use of space.
Maximizing Storage Density
The primary goal was to increase storage capacity within the existing footprint. New Horizon selected high-density mobile shelving on tracks. This system eliminates static aisles between each row of shelves, compacting the units together and creating a single, movable aisle. This approach can double storage capacity compared to traditional static shelving.
Mitigating Moisture Risks
A previous incident involving an overhead equipment leak damaged valuable tissue inventory. To prevent this from happening again, the new system required a solid metal top cover. This feature acts as a shield, deflecting drips from pipes or ceiling-mounted equipment away from the stored samples below.
Optimizing Shelf and Bin Size
The facility was upgrading from 16-inch deep shelves to 24-inch deep shelves. This change allows them to store larger storage bins two-deep, making more efficient use of the available space. This deeper profile is a key feature of modern laboratory shelving systems designed for bulk biologicals.
Adding Containment Features
To further protect inventory, the design included side guards and containment ledges. Side guards on all exposed sides prevent bins or boxes from falling off the shelves during carriage movement. Containment ledges on each shelf tier help contain minor spills and limit liquid migration to lower levels.
Ensuring Future Flexibility
A critical requirement was that the entire system must be relocatable. New Horizon planned to move to a new facility within one to two years. The chosen mobile shelving system is modular, meaning it can be disassembled, moved, and reassembled at the new location, protecting the initial investment.
Layout and Track Strategy
The proposed layout consisted of a four-section system. The main storage area would use a high-density track measuring 27 feet and 11.5 inches long. This single track would support three rolling shelving sections, providing approximately 396 inches (33 feet) of linear storage space.
The track itself was specified in seven-foot modules. This modular approach simplifies installation and aligns with the rolling unit dimensions, making future expansion or reconfiguration more straightforward. The plan also allowed for static bays of complementary laboratory shelving systems for frequently accessed materials.
Moisture-Mitigated Features in Detail
The design focused on practical solutions for everyday water risks. While a fire sprinkler activation remains an uncontrollable event, the system effectively mitigates more common threats.
The solid metal top cover is the first line of defense against overhead leaks from plumbing, HVAC units, or other equipment.
Below the top cover, containment ledges on each shelf tier provide a secondary barrier. These small raised edges can contain a small spill from a single container, preventing it from spreading across the shelf or dripping onto samples below. The use of durable wire lab shelving with these accessories offers a robust, multi-layered solution.
Vendor Collaboration and System Fit
To ensure the solution met the specific demands of a laboratory environment, Labs USA partnered with Metro, a leading manufacturer of lab-grade mobile systems. Metro provided expert guidance on track spacing, carriage mechanics, and material specifications suitable for biological storage.
The collaboration relied on detailed drawings and site photos shared between the client, Labs USA, and Metro. This visual coordination was crucial for finalizing the configuration before any equipment was ordered. This integrated approach ensures all pieces of laboratory furniture work together as a cohesive system.
The Importance of Field Verification
To prevent costly ordering errors, the client committed to performing on-site field verification. Before giving final approval, the New Horizon team used a tape measure to confirm all critical dimensions. They double-checked the available length, depth, and ceiling clearances in the storage room. This simple step is vital for ensuring the system fits as planned and avoids installation delays.
Communication Agility and Problem-Solving
Even the best-laid plans can encounter small hurdles. During a critical planning meeting, a technical issue prevented a key participant from joining the video conference. Instead of postponing, the team adapted quickly. They switched to a phone call and used shared visual aids to keep the discussion moving forward. This agile communication prevented delays and demonstrated a commitment to collaborative problem-solving.

By focusing on detailed requirements, collaborative design, and careful verification, the team created a system that protects valuable assets while optimizing lab space.
Choosing the right lab workstations and tables is a foundational decision for any laboratory. It is about more than having a place to set equipment. It involves creating a space that is safe, efficient, and supports your team’s work. A heavy-duty workstation might be a permanent home for complex instruments, while a mobile table offers the flexibility to move samples or change layouts. Understanding these differences is the first step in setting up a functional workspace.
Key Takeaways
Match Function to Workflow: Choose fixed tables for routine tasks, adjustable workstations for ergonomics and multi-user settings, and mobile tables for flexibility in R&D or dynamic spaces.
Plan Meticulously: A five-step planning process covering workflow, space measurement, load capacity, utility needs, and ergonomics prevents costly mistakes.
Select Materials Wisely: The choice between epoxy resin, phenolic resin, and other work surfaces depends on chemical, heat, and moisture resistance requirements. Frame materials like powder-coated steel and stainless steel impact durability and corrosion resistance.
Understanding Your Workspace Options
Choosing a surface and frame is like selecting the right tool for a job. Each lab bench has a purpose. Matching the furniture to the task prevents workflow issues and potential safety problems. We can break down options into three main categories: fixed tables, adjustable workstations, and mobile tables.
Fixed Tables
Fixed tables are the workhorses of the lab. They provide a sturdy, permanent surface for routine tasks or dedicated equipment. You often see these in quality control or clinical settings where processes are standardized and repeated. Their simple design and durability make them a cost-effective choice for any high-throughput environment.
Adjustable Workstations
Adjustable workstations offer ergonomics and flexibility. They are useful for multi-user labs or for tasks that demand specific height adjustments. Many of our technical workstations with service uprights also integrate power, data, and utility connections directly into the frame. This creates a self-contained hub for complex work.
Mobile Tables
Mobile tables and carts bring a high level of adaptability to your space. Set on casters, they can be rolled where you need them. You can create a temporary work area, move materials between stations, or reconfigure a room for a new project. This is very helpful in research and development labs where workflows change frequently.
Most modern labs do not stick to just one type. They often create a hybrid system. A lab might have a fixed perimeter of casework and tables, with adjustable workstations for key analytical instruments. A fleet of mobile carts for sample prep and transport adds flexibility. This mix provides a space that is both structured and dynamic.
Your 5-Step Planning and Selection Checklist
Planning your lab layout can feel like a large task, but a structured process makes it manageable. This five-step checklist is a roadmap for facilities managers and lab directors. Each step breaks down the job of selecting furniture into smaller tasks so nothing important is missed. Following this plan helps you choose the right lab workstations and tables for your team.
Step 1: Define Your Lab’s Workflow
Before considering furniture, observe how your lab works. Map the daily journey of samples, equipment, and people. Understanding this flow is key to matching the right furniture to each activity. A busy clinical lab might need long, stationary benches for automated analyzers. In contrast, a flexible research lab needs mobile tables that can be reconfigured for different projects.
Step 2: Measure Your Space and Clearances
Next, get precise measurements of your floor space. Note the locations of every door, window, column, and utility hookup. Plan for the space around the furniture, as clearances are necessary for safety and function. Check your local building codes and internal safety rules, but use these as a starting point:
Aisle Width: Allow 36 to 42 inches for people to pass easily.
Egress Paths: Keep all emergency exit routes completely clear.
Equipment Access: Leave space around instruments for maintenance and ventilation.
ADA Accessibility: Accessible workstations must meet rules for height, knee clearance, and reach range.
Step 3: Calculate Load Capacity Needs
You need to know how much weight your workstations will hold. Consider both static load (the constant weight of equipment) and dynamic load (stress from machines in operation or heavy items). Add up the weights of all equipment you plan to put on each surface. Always add a safety buffer of at least 25% to your final number for future upgrades. Workstation load ratings can range from a few hundred pounds to over 2,000 pounds.
Step 4: Identify Essential Utility Needs
A modern lab bench is more than a flat surface. List every utility connection each workstation will need. This may include electrical power, data ports, specialty gases, or vacuum and water lines. Many technical workstations come with service uprights that manage these connections safely. Figuring out utility needs from the start ensures your new furniture integrates with your building’s infrastructure.
Step 5: Prioritize Ergonomic and Adjustable Features
Finally, think about the people using the furniture. Repetitive motions and long hours standing or sitting can cause strain. Features like height-adjustable lab workstations are important. They let users switch between sitting and standing, which reduces fatigue. Look for options with a simple manual crank or a smooth electric lift. Good ergonomics is a fundamental part of a safe and productive lab.
Comparing Frame and Work Surface Materials
The materials you choose for your lab furniture affect its lifespan, safety, and function. The frame is the skeleton, and the work surface is the skin. Each part must stand up to the unique demands of your lab. Let’s review the most common materials for both.
Frame Materials: The Workstation Foundation
The frame provides structural support. It must resist corrosion, handle heavy loads, and remain stable.
Powder-Coated Steel: This is a common and cost-effective material. A tough layer of powder is baked onto the steel, creating a durable, scratch-resistant finish. It is a great choice for most general lab applications.
Stainless Steel: For sterility and corrosion resistance, stainless steel is the best choice. It is ideal for cleanrooms, biological labs, and facilities needing frequent wash-downs. Its non-porous surface is easy to clean.
Aluminum: Aluminum frames are lightweight and naturally resist corrosion. They are often used for mobile tables or in labs where furniture is moved frequently.
Work Surface Materials: The Point of Contact
The work surface must withstand chemical spills, heat, and impacts. Choosing the right surface protects your experiments, equipment, and team.
Epoxy Resin: For labs with harsh chemicals, epoxy resin is the top choice. It is a solid, non-porous material with great resistance to acids, solvents, and high heat. It is easy to clean and decontaminate.
Phenolic Resin: Phenolic resin offers a good balance of performance and value. It is made by pressing layers of resin-saturated paper under heat and pressure. The result is a tough surface that resists chemicals, moisture, and bacteria.
Chemical-Resistant Laminate: This is a budget-friendly option for light-duty lab environments. It handles common cleaning agents and mild chemicals well. It is not recommended for labs using highly corrosive substances or high heat.
Stainless Steel: Like frames, stainless steel work surfaces are best for sterile applications. They are essential in pharmaceutical and food science labs. The surface is easily sterilized and will not harbor bacteria.

Integrating Workstations with Casework and Utilities
An effective lab is an integrated system. Your new lab workstations and tables must work with your existing infrastructure. This means planning how mobile tables will align with fixed casework. It also means planning how benches will connect to your building’s utility grid. Proper integration turns individual pieces into a single, functional workspace.
Aligning Mobile Tables with Fixed Casework
Pairing mobile tables with fixed casework is a smart way to build flexibility. A mobile table can extend a permanent counter, letting your team create U-shaped or L-shaped work cells as needed. The key is to ensure the height of your mobile tables matches the height of your fixed casework countertops. This creates a seamless work surface.
Connecting to Ceiling Service Panels
For labs with many instruments, ceiling service panels are a clean and efficient way to deliver utilities. By placing technical workstations with service uprights under these panels, you can use flexible overhead connections to drop services where needed. This approach keeps floors clear of cables and hoses, which improves safety and makes cleaning easier.
Leveraging Vertical Space with Shelving
Your lab’s vertical space is valuable. Integrating bench and wall shelving that integrates with workstations multiplies your storage capacity without using more floor space. Overhead shelves keep supplies off the primary work surface but within reach. This declutters your work area and creates a safer, more efficient lab. The casework compatibility with mobile tables is also important for creating a cohesive and adaptable system.
5 Decision Scenarios for Your Lab
To see these concepts in action, let’s review five common lab scenarios. Each mini-guide outlines a specific challenge and suggests a furniture solution.
1. High-Throughput Clinical Lab
The Scenario: A busy clinical lab processes hundreds of samples daily. The workflow involves automated analyzers in a precise line. Surfaces must be durable, easy to clean, and resistant to disinfectants.
The Solution: Fixed tables with epoxy resin tops are ideal. The fixed layout provides a stable base for sensitive equipment and maintains an optimized workflow. The seamless, non-porous epoxy surface is easy to decontaminate, which is essential for a sterile environment.
2. Shared R&D or University Lab
The Scenario: In a university lab, multiple teams share the space. One day, a team needs a tall analytical instrument. The next day, another group needs a standard-height bench. The furniture must adapt to different people and equipment.
The Solution: Height-adjustable workstations are the answer. An electric lift allows users to change the surface height easily. This accommodates various instruments and allows users to switch between sitting and standing for better ergonomics.
3. Quality Control and Materials Testing Lab
The Scenario: QC technicians are constantly moving. They prep samples in one area, move them to a microscope, and then to a final testing bench. The workflow is fluid, and a rigid layout would cause bottlenecks.
The Solution: Mobile worktables are a perfect fit. Technicians can use these carts to shuttle samples between stations. This mobility creates an agile workflow, allowing the team to reconfigure the lab as testing needs change.
4. Electronics and Cleanroom Labs
The Scenario: When working with sensitive electronics, electrostatic discharge (ESD) can damage components. The workspace must safely ground any static buildup.
The Solution: Workstations with ESD-laminate work surfaces are essential. These specialized tops dissipate static electricity away from components, protecting them from damage.
5. Wet Chemistry Lab
The Scenario: A wet chemistry lab involves frequent use of acids, bases, and solvents. Spills are common, and surfaces must withstand harsh chemical exposure without degrading. High heat from hot plates is also a factor.
The Solution: Fixed workstations with epoxy resin tops and integrated sinks are the standard. Epoxy offers superior resistance to a wide range of chemicals and heat. An integrated sink provides a safe, convenient place for rinsing glassware and disposing of liquid waste.
Frequently Asked Questions (FAQs)
Here are answers to common questions about lab workstations and tables.

In any lab, a fume hood is a key piece of safety equipment. Its main job is to protect you from breathing in harmful fumes, vapors, and dust during your work. It acts like a powerful ventilation system that pulls contaminants away from your workspace, reducing your exposure to toxic or volatile chemicals.
What You Need to Know
Primary Purpose: A fume hood protects users from inhaling hazardous fumes, vapors, and dust.
How It Works: It creates a contained workspace with steady airflow, pulling contaminated air away from the user and exhausting it safely.
Key Functions: It contains spills and splashes, shields users from reactions, and keeps the lab’s air clean.
Main Types: Ducted hoods vent air outside the building, while ductless hoods filter the air and recirculate it.
Safety First: Always work with the sash low, keep equipment at least six inches inside, and never use a fume hood for chemical storage.
Understanding the Role of a Fume Hood in Lab Safety
A fume hood is like the exhaust fan over your stove, but much more powerful and designed for scientific work. Instead of just removing cooking smoke, it handles dangerous materials. It creates a contained area that constantly pulls air from the lab, across your work surface, and then through an exhaust system.
This steady airflow is what makes it so effective. By pulling contaminated air away from the user’s breathing zone, the fume hood acts as a primary engineering control. This means it is a physical barrier between the scientist and the hazardous process inside.
The Primary Safety Functions
A fume hood has three core safety jobs in the lab. Each one is critical for keeping everyone safe.
Protecting Users from Inhalation: This is its most important job. It captures toxic vapors, gases, and airborne particles at the source. This prevents them from reaching the lab worker’s lungs.
Containing Spills and Reactions: The enclosed design features a movable glass window called a sash. This sash is perfect for containing chemical spills and splashes. It also acts as a shield from unexpected reactions or minor explosions.
Keeping the Lab’s Air Clean: A fume hood vents hazardous fumes completely out of the building. This stops contaminants from building up in the lab’s air. This helps maintain clean, safe air for everyone in the room.
How the Main Parts of a Fume Hood Work Together
To understand what a fume hood is used for, you must see how its parts operate as a single safety system. Think of it as a controlled vacuum. Each piece has a job in capturing and removing harmful airborne materials before they reach the user.
This coordinated effort ensures that hazardous fumes, vapors, and dust are pulled away from the person doing the work. Every component is designed to create a safe, contained workspace.
The Main Structure and Enclosure
The first thing you notice is the hood body, which is the large box-like enclosure. This structure is the primary physical barrier between the lab professional and their chemical process. It is almost always built from tough, chemical-resistant materials.
Inside this enclosure is the work surface. This is the area where experiments happen. This surface is also made of durable, non-porous materials like epoxy resin or stainless steel. It is designed so any spills are contained and can be cleaned up easily.
Controlling Airflow for Maximum Safety
One of the most vital safety features is the sash, the movable glass window at the front. The sash has two critical functions. First, it is a physical shield that protects the user from chemical splashes or unexpected reactions.
Second, the sash position controls the airflow into the hood. When you lower the sash, you shrink the opening. This forces the air to move faster as it enters, which improves containment. You should always work with the sash at the lowest practical height.
At the back of the fume hood are the baffles. These are slotted panels that are crucial for creating a smooth, uniform flow of air across the work surface. Baffles prevent dead spots and ensure contaminants are swept away from every corner.
Finally, the exhaust system, made of ductwork and a powerful fan, pulls air through the whole setup. Air is drawn from the lab, through the sash opening, across the work surface, past the baffles, and into the ductwork. From there, it is safely vented outside the building.
Exploring different types of laboratory hoods and enclosures shows how systems are tailored for specific jobs. In every case, each component works together to keep personnel safe.
Comparing Ducted and Ductless Fume Hoods
Not all fume hoods are the same. The biggest difference is how they remove contaminated air. The two main types are ducted and ductless fume hoods. Knowing which one is right for your lab is important for safety and your budget.
A ducted fume hood vents contaminated air completely out of the building. A ductless fume hood uses filters to clean the air and returns it to the room. Each type has its place, and the choice depends on what you are working with.
The Role of Ducted Fume Hoods
The ducted fume hood is the traditional choice for most labs. It connects to your building’s HVAC system through ductwork. It pulls hazardous fumes from your workspace and expels them outside, usually through a roof fan.
Because it completely removes contaminants, a ducted hood is very versatile. It is the best choice when you deal with many different chemicals, highly volatile substances, or unknown compounds. You do not have to worry about a filter failing.
However, the installation is a major project that ties the hood to a fixed location. Ducted hoods also use a lot of energy. Every cubic foot of air they exhaust is conditioned air that your HVAC system must replace.
Understanding Ductless Fume Hoods
Ductless fume hoods offer a more flexible and often more affordable option. Instead of sending air outside, these units pull fumes through heavy-duty filters, like activated carbon or HEPA filters. They clean the air before recirculating it back into the lab.
This all-in-one design has some big advantages. Installation is often as simple as finding a spot and plugging it in. Many models are on wheels, letting you rearrange your lab easily. They are also more energy-efficient because you are not dumping heated or cooled air outside. For labs with specific chemical processes, ductless fume hoods can be a smart choice.
The main drawback involves the filters. The filter type must be matched to the specific chemicals you use. They also need to be monitored and replaced regularly, which adds an ongoing cost.
Fume Hoods vs. Biological Safety Cabinets
It is easy to confuse a chemical fume hood with a biological safety cabinet (BSC), but they have different purposes. They are not interchangeable.
Chemical Fume Hoods: Their only job is to protect you, the user, from breathing in harmful chemical fumes. They offer zero protection to your sample inside.
Biological Safety Cabinets (BSCs): These are built to protect the user, the environment, and the product inside. They use sterile HEPA-filtered air to create a clean work zone for cell cultures or microorganisms.
Never use a biological safety cabinet for work with volatile or hazardous chemicals. Chemical vapors can pass through HEPA filters, damage them, or be recirculated back into your lab.
Ducted vs. Ductless Fume Hood Comparison
Choosing between a ducted and ductless system requires a clear look at the chemicals you handle, your building, and your budget. This table breaks down the key differences.

Real-World Fume Hood Applications
To see what a fume hood is used for, you must look at where it appears in the real world. You will find them in a wide range of industries, protecting people from hazardous materials every day.
Whether it is a university lab or a large industrial plant, the job is always the same. It is to give people a safe, ventilated space to handle volatile materials.
University Chemistry Labs
In a university chemistry program, the fume hood is essential for students. In an organic chemistry lab, students work with volatile solvents like acetone and ethanol. The fumes can be flammable and harmful if inhaled.
A fume hood lets students run experiments like distillation without exposing the whole room to airborne hazards. It provides a controlled space where they can learn safely.
Pharmaceutical Research and Development
Pharmaceutical labs often work with potent and volatile chemical compounds. When creating new drugs, researchers handle strong acids, bases, and organic solvents.
In this environment, fume hoods are critical. They protect scientists from constant exposure to these substances and ensure the lab’s air stays clean. This is necessary for both team safety and the integrity of sensitive experiments.
Clinical and Hospital Laboratories
Clinical labs run tests on patient samples. This often means using chemicals to prepare those samples. For example, a histology lab uses chemicals like formaldehyde and xylene, which are known to be toxic.
Here, fume hoods provide a safe zone for tasks like fixing and staining tissue samples. The constant airflow pulls dangerous vapors away from the technician, reducing health risks from long-term exposure.
Industrial Quality Control
Many manufacturing industries use quality control labs to check materials and products. This might involve dissolving a sample in a strong acid or running a test that gives off noxious gases. For example, a lab might use nitric acid to analyze metal alloys.
Fume hoods in these settings are essential for containing corrosive fumes and protecting technicians. This shows how fume hoods support workplace safety and product quality.
5 Common Use Case Scenarios
Here are a few scenarios to see how the decision-making process works.
University Teaching Lab: A university needs to outfit a new organic chemistry lab. The main goal is protecting students from common solvents. A standard ducted benchtop fume hood is the best solution for broad chemical resistance.
Pharmaceutical Synthesis: A research team is creating a new drug compound using highly potent chemicals in small amounts. A high-performance ducted fume hood with a Variable Air Volume (VAV) system offers maximum protection and energy efficiency.
Clinical Pathology: A hospital’s histology department needs a dedicated spot for preparing slides with formaldehyde. A special formaldehyde-rated ducted fume hood is required to capture the carcinogenic vapors.
Cosmetic Product Development: A cosmetic lab is mixing new fragrances using volatile organic compounds (VOCs). They need a safe area for creating small batches. A real-world example shows how a fume hood for a cosmetic lab in Utah was the right choice.
Industrial Acid Digestion: A quality control lab regularly digests metal samples using perchloric acid. They need a dedicated perchloric acid fume hood with a wash-down system to prevent a dangerous buildup of explosive residue.
How to Choose the Right Fume Hood
Picking a fume hood is a major decision that affects safety, workflow, and your budget. With so many types and features, you have to get it right. The goal is to match the equipment to your specific work.
The best approach is a clear, step-by-step process. By answering a few key questions, you can find the perfect fit for your lab.
Your 5-Step Selection Checklist
Follow these five steps to choose the right fume hood for your lab’s needs.
1. Assess Your Chemical Use
First, identify what you will put in the hood. The chemicals you handle will define what kind of system you need.
What chemicals will be used? Make a detailed list. If you work with corrosive materials like perchloric acid, you will need a specialized fume hood.
How much of each chemical will be used? Small amounts might be suitable for a ductless hood. Large quantities of hazardous substances usually require a ducted system.
Will the processes generate heat? High-heat experiments may require a hood made from more durable materials.
2. Evaluate Your Facility and Space
Next, look at your building. A fume hood must work with your lab’s layout and infrastructure.
Do you have existing ductwork? If your building has a suitable exhaust system, a ducted fume hood is a good choice. If not, a ductless model may be more practical.
How much space is available? Measure the area. Consider the width of the hood, ceiling height, and space for people to work safely around the unit.
3. Determine Size and Required Features
Now you can focus on the hood itself. This is about matching the equipment to your daily workflow.
What size hood is needed? Fume hoods typically range from 3 to 8 feet wide. Choose one large enough for your procedures to avoid clutter, which can disrupt airflow.
What utilities are required? Think about what you will need inside the hood, such as gas, compressed air, or water. Many models can be ordered with pre-plumbed fixtures.
4. Consider Energy and Operating Costs
A fume hood is a long-term investment. The purchase price is only part of the story. Ongoing operating costs, especially for energy, can be high.
Constant Air Volume (CAV) vs. Variable Air Volume (VAV): A CAV system runs at full exhaust power all the time. A VAV system adjusts airflow based on the sash position. VAV systems cost more upfront but can save a lot on energy bills.
Ductless Filter Costs: If you choose a ductless hood, remember to budget for filter replacements.
5. Verify Safety and Compliance Standards
Finally, make sure any hood you consider meets all necessary safety certifications. Compliance is essential for protecting your team.
Check for ASHRAE 110 certification: This is the standard for fume hood performance testing. It verifies that the hood can contain and exhaust fumes effectively.
Consult your Environmental Health & Safety (EHS) officer: Always involve your organization’s safety experts. They can provide specific guidance and ensure your choice meets all regulations.
Best Practices for Fume Hood Safety and Maintenance
A fume hood is only as effective as the person using it. Proper use and regular upkeep are essential to ensure the hood provides maximum protection.
Following consistent safety protocols and a simple maintenance schedule is the best way to create a safer lab. It also helps extend the life of this critical piece of equipment.
Essential Safety Protocols
Using a fume hood correctly involves more than just turning on the fan. The airflow that contains fumes is delicate and can be easily disrupted. Every user should follow these guidelines.
Maintain Sash Height: Always work with the sash at the lowest practical position. Most hoods have a sticker indicating the certified working height.
Work Deep Inside the Hood: Keep all chemicals and equipment at least six inches back from the face of the hood. Working too close to the front can pull contaminants out into your breathing space.
Avoid Clutter: An overcrowded workspace is dangerous. Clutter can block airflow slots at the back of the hood, creating dead spots where contaminants can escape.
Minimize Sudden Movements: Quick motions can disrupt the air curtain and pull fumes out into the lab. Always move slowly and deliberately.
Confirm Airflow: Before you start work, verify that the fume hood is drawing air. Most modern hoods have an airflow monitor or an alarm.
A full lab safety plan is also vital. This includes having ready access to emergency shower and eyewash stations to handle accidental chemical exposures.
Routine Maintenance and Certification
Proper upkeep ensures your fume hood performs as designed. A consistent maintenance plan can prevent equipment failure and protect your team. Always check with your facility’s Environmental Health and Safety (EHS) department before performing any maintenance.
A solid maintenance schedule should include daily, weekly, and annual checks.
Daily Visual Checks: Before each use, inspect the sash to make sure it moves smoothly. Check the airflow monitor to confirm it is on and in the safe range.
Weekly Cleaning: Wipe down the interior surfaces and the sash with an approved cleaning agent. This prevents residue buildup.
Annual Certification: A qualified technician must test and certify your fume hood at least once a year. This certification verifies that the performance meets safety standards like ASHRAE 110.
By combining safe work habits with a proactive maintenance schedule, you can be confident that your fume hood remains a reliable part of your lab’s safety program. For more details, review our guide to fume hood safety.
6 Frequently Asked Questions About Fume Hoods
Here are clear answers to the most common questions about fume hoods.
1. What is face velocity and why does it matter?
Face velocity is the speed of the air being pulled into the front opening of the fume hood, measured in feet per minute (FPM). It is a key metric for hood performance. If the face velocity is too low, fumes can drift out. If it is too high, it can create turbulence that also pushes fumes out. Most standards recommend a face velocity between 80 and 120 FPM.
2. Can a fume hood be used for chemical storage?
No. Using a fume hood for chemical storage is a major safety violation. Storing items inside blocks airflow, increases fire risk, and reduces your safe working area. Chemicals belong in approved safety cabinets.
3. What is the difference between CAV and VAV systems?
Constant Air Volume (CAV) systems pull the same amount of air all the time, regardless of sash position. They are simpler but use more energy. Variable Air Volume (VAV) systems adjust the fan speed based on the sash height, saving significant energy while maintaining a safe face velocity.
4. How often do fume hoods need to be certified?
Fume hoods require professional testing and certification at least once every year. This is a safety requirement mandated by organizations like OSHA. A certified technician will measure face velocity and check for proper airflow.
5. Do I need a special fume hood for perchloric acid?
Yes, you must use a specialized perchloric acid fume hood when working with heated perchloric acid. Vapors from this chemical can form explosive crystals. These dedicated hoods are built with specific materials and have an integrated wash-down system to clean away dangerous residue.
6. What should I do if the fume hood alarm sounds?
If the alarm sounds, it means the airflow is too low for safe operation. Stop your work immediately, lower the sash completely, and leave the area. Notify your lab supervisor or EHS officer right away. Do not use the hood until it has been inspected and repaired by a qualified technician.
Conclusion
A fume hood is more than just lab furniture. It is a critical piece of engineering designed to protect you, your work, and your lab from hazardous fumes. Understanding how they work, the different types available, and how to use them properly is essential for lab safety.
Now that you have a clear picture of what a fume hood is used for, you are ready for the next step. You can explore our extensive selection to find the right equipment for your application. If you need help, our experts are here to help you plan the perfect layout for your facility.
A thoughtful lab bench configuration is the foundation of a safe, efficient laboratory. The right layout directly impacts workflow, sample throughput, and staff hygiene. Proper planning ensures your space, equipment, and utilities work together without issues.
Getting the design right from the start avoids costly installation problems. It also creates a workspace that is functional today and adaptable for the future. This guide uses a real project to show how Labs USA helps clients plan every detail, from bench dimensions and sink placement to custom solutions for angled walls. We configure lab workstations and tables and technical workstations to support specific tasks, making every inch of your lab productive.
Key Steps for Lab Bench Configuration
Plan for Workflow: Design C-shape and L-shape benches to match specific tasks like sample processing or blood bank analysis.
Verify Dimensions: Use live measurements of instruments to set bench lengths and depths, not just spec sheets.
Integrate Utilities: Place sinks, DI water spigots, power, and data ports strategically during the drawing phase.
Use Field-Fit Solutions: For angled walls or obstructions, plan to cut countertops on-site for a perfect fit without project delays.
Select Materials Wisely: Choose non-porous surfaces and use integral backsplashes only where needed to control costs and maximize usable space.
1. Area 3 — C-Shape Bench for Sample Processing
For a high-volume sample processing area, a C-shape bench offers an efficient and contained workspace. This layout keeps everything within reach and creates a clear workflow path. A recent project required a custom C-shape configuration that balanced standard tasks with the needs of larger equipment.
Footprint and Depth
The final footprint was a 9 ft by 9 ft by 9 ft C-shape. The side benches were planned at a 24-inch depth, which is ideal for standard tasks where technicians need close access. The back run of the bench was specified at a 36-inch depth. This extra space comfortably accommodates larger instruments and allows for cable management behind them.
Sink Plan and Modularity
A single-bowl sink was placed in the center of the back run. This divided the workspace into a 4-foot surface on the right and a 3-foot surface on the left, specifically for a urine sample workflow. The faucet was chosen to help reduce odors from the drain, a small detail that improves the work environment.
To maintain structural rigidity, the bench was built by combining 3-foot and 4-foot lab workstations and tables. This modular approach creates a strong, unified structure.
Backsplash and Work Surfaces
An integral 4-inch backsplash was included only at the sink area to contain splashes. It is important to note that an integral backsplash reduces the usable depth of a work surface by about one inch. Limiting the backsplash to wet areas preserves the full depth of other surfaces for equipment. To learn more about material options, it is helpful to understand how to choose the right lab work surface to complete your project.
2. Area 2 — Compact DI Sink and Instrument Line
In another area, a long run of analytical instruments required a dedicated deionized (DI) water source. This is a common need in labs performing sensitive procedures where water purity is critical. The design had to integrate a specialized sink and a precise bench length to fit specific equipment.
Compact Sink Design
To save counter space, a compact 2 ft by 2 ft sink was specified. It was equipped with both a standard faucet and a DI spigot. This dual-faucet setup provides flexibility for different tasks without cluttering the workspace. Proper integration of DI plumbing is a key feature of well-planned technical workstations and tables.
Instrument Verification
The initial plan allocated a 7-foot bench for a key analyzer based on the manufacturer’s spec sheet. However, a live measurement of the actual instrument on-site revealed it required exactly 78 inches. This revision was critical. Adjusting the bench length before fabrication ensured a perfect fit and avoided workflow issues.
A consistent 3-foot depth was used for the entire instrument run. This provides ample clearance for cables and service lines behind the equipment. It also creates a uniform and organized appearance.
3. Area 7 — Blood Bank L-Bench with Lighting and Shelves
Blood bank workflows require organized, well-lit spaces. For this project, an L-shaped bench was designed for a room with an angled wall. This situation required a custom solution to ensure a seamless installation without delaying the project timeline.
Layout, Lighting, and Rails
The L-bench layout measured 8 ft by 9 ft with a standard 24-inch depth. The longer 9-foot side was equipped with integrated lighting, uprights, and two shelves. The shelves were 12 inches deep to provide accessible storage for supplies while maintaining adequate headroom for technicians. This type of integrated storage is a core component of modern laboratory casework.
Angled Wall Solution
The room’s corner was not a standard 90-degree angle. One wall had a straight section of 81 inches that transitioned to a 24-inch angled section. Prefabricating a countertop for this unique angle would be risky and expensive.
The solution was to plan for field cutting. A slightly oversized countertop was sent to the site, where installers cut it to match the wall’s exact angle. This practical approach ensures a perfect fit. For guidance on these types of configuration choices, it is helpful to review details on laboratory casework.
4. Materials, Sinks, and Hygiene
Choosing the right materials is essential for maintaining a clean and durable lab environment. Work surfaces must withstand daily cleaning and potential chemical exposure.
How to Choose Materials and Features
Assess Chemical Resistance: Identify all chemicals used in your workflow. Select a non-porous work surface material like epoxy resin or phenolic resin that can tolerate them.
Evaluate Hygiene Needs: Choose smooth, seamless surfaces that are easy to decontaminate. An integral backsplash is ideal for wet areas around sinks.
Plan for Splashes: Place integral backsplashes only at sinks. This controls costs and preserves maximum usable depth on dry work surfaces.
Specify Sink and Faucet: Select sink bowl sizes that accommodate your largest glassware or equipment. Choose faucet types, like gooseneck or sprayer models, that match your sample handling needs.
Confirm Durability: Consider the physical demands of your lab. Will surfaces need to resist scratches, heat, or heavy impacts? Choose a material that meets these requirements.
Successful lab design depends on precise measurements and careful integration of all equipment. Relying on actual dimensions instead of spec sheets is a critical step.
Key Integration Practices
Use Actual Dimensions: Always measure your instruments before finalizing bench spans and depths. This prevents spacing issues and ensures a perfect fit.
Maintain Standard Depths: Use a consistent depth for mobile tables and fixed benches whenever possible. This helps maintain proper clearances and ensures ADA accessibility.
Confirm Utilities Early: Finalize the locations of DI lines, power outlets, and accessory rails in the drawing phase. This avoids costly changes during installation.
Well-planned lab workstations and tables include integrated options for power and accessories, creating a clean and organized workspace.
6. Photos, Drawings, Approvals, and Release
A structured approval process is key to keeping a laboratory installation on schedule, especially for new facilities. Clear communication and phased fabrication prevent delays.
The Approval Sequence
Client Photos: The client provides photos of any non-standard areas, such as the angled wall in Area 7.
Drawing Updates: Labs USA updates the drawings with precise details based on the photos and final measurements.
Client Approval: The client reviews and approves the final drawings, which releases the components for fabrication.
Fabrication can begin on confirmed areas while details for custom sections are finalized. For this project, the client’s payment triggered an immediate order for all materials. This proactive approach ensures the project meets its target schedule. Proper management of laboratory casework from design to installation is crucial. This coordination ensures all casework components arrive ready for a smooth installation.

Labs USA coordinates every step, from drawings and material selection to fabrication release, to meet the strict timelines of new facilities. This detailed approach results in a workspace that is efficient, safe, and built to last.
1. What is the standard depth for a lab bench?
The standard depth is typically 24 inches for manual tasks like pipetting or microscopy. For benches holding larger instruments, a depth of 30 or 36 inches is common to provide space for cables and ventilation.
2. How do you handle an angled wall or column in a lab design?
We use a method called field cutting. A countertop is cut on-site to perfectly match the angle of the wall or fit around a column. This provides a custom fit without the high cost and long lead time of a fully custom-fabricated top.
3. Should I put a backsplash on all my lab benches?
An integral backsplash is most useful in wet areas, such as around a sink, to contain splashes. On dry benches, forgoing a backsplash maximizes the usable work surface depth and offers more flexibility for placing equipment.
4. Can I mix different bench depths in the same room?
Yes. Mixing depths is a smart way to optimize a layout. For example, you can use 24-inch deep benches for general work and a 36-inch deep section for a line of instruments, all within a single C-shape or L-shape configuration.
5. How are utilities like DI water integrated into casework?
Utilities like DI water, gas, and power are planned during the drawing phase. Lines are typically routed through the casework or a dedicated utility chase. Fixtures are mounted on the benchtop or service panels for easy access. Confirming these locations early is critical.
6. How do I choose the right work surface material?
The best material depends on the chemicals and processes used in your lab. Non-porous surfaces like epoxy resin and phenolic resin are popular choices due to their high chemical resistance and durability. Always refer to chemical resistance charts to match the material to your needs.
7. How long does the design and fabrication process take?
The timeline varies based on project complexity. A typical project involves a few weeks for design and drawing approvals, followed by a standard fabrication lead time. We can start fabricating confirmed areas while finalizing custom details to keep the project on schedule.
8. Do you provide installation services?
Yes, Labs USA coordinates with experienced laboratory furniture contractors to provide professional installation services across the country, ensuring your lab is set up correctly and safely.
