Laboratory Phenolic Casework: Selection, Integration, and Maintenance

Marketing Manager

When you need lab cabinets that stand up to harsh conditions, phenolic casework is a leading choice. It is a high-performance system built from solid phenolic composite panels, earning a reputation for its exceptional resistance to chemicals, moisture, and impact. This makes it an incredibly durable option for the tough environments found in many laboratories.

Unlike traditional wood that can swell or metal that can rust, phenolic material does not delaminate, warp, or corrode when exposed to frequent spills or high humidity.

Key Takeaways

  • Exceptional Durability: Phenolic casework offers superior resistance to a wide range of chemicals, moisture, and impact, making it ideal for wet labs and high-use environments.
  • Low Lifecycle Cost: While the initial investment may be higher than laminate, its long service life and minimal maintenance needs result in a lower total cost of ownership.
  • System Integration: Phenolic casework pairs effectively with various work surfaces like phenolic resin, epoxy resin, and stainless steel, and integrates seamlessly with laboratory shelving systems.

What Is Phenolic Casework?

The process for creating phenolic casework begins with layers of kraft paper saturated in phenolic resin. These layers are fused together under intense heat and pressure. This creates a solid, non-porous panel that is incredibly dense and stable.

It is important to distinguish phenolic casework (the cabinets and drawers) from the phenolic work surfaces it supports. While made from similar materials, the casework forms the structural body of your storage. The countertops, in contrast, are specifically engineered to handle the direct abuse of chemicals, heat, and daily wear. The concept that phenolic tops and casework goes together creates a uniformly resistant workstation.

Modern labs in biotechnology, research, and education are increasingly choosing phenolic over steel or wood. Its ability to resist a wide range of chemicals and constant moisture means it does not break down easily. This toughness translates to a lower total cost of ownership because you avoid frequent repairs or replacements.

The manufacturing process also creates a surface that naturally resists bacterial growth. This is a crucial feature for clinical and biological labs. Phenolic casework delivers a solid foundation for a lab that is safe, clean, and efficient.

Choosing the right laboratory phenolic casework is a critical decision. It depends on a practical assessment of your lab’s daily operations. A correct choice results in a safe, functional, and long-lasting workspace.

To help you make a smart investment, follow these five straightforward steps.

Step 1: Analyze Chemical and Moisture Exposure

First, identify all chemicals used in the lab. List the acids, bases, solvents, and cleaning agents that may come into contact with your cabinetry. Note their concentrations and frequency of contact.

Also, evaluate the moisture levels. Labs with constant wash-downs, high humidity, or integrated sinks create tough environments. You need a material like phenolic that will not swell, warp, or support mold growth.

Step 2: Calculate Load-Bearing and Storage Needs

Next, consider the weight of stored items. Account for everything from heavy benchtop equipment to bulk reagent containers and glassware. Every cabinet and shelf has a specific load rating. Exceeding this limit can lead to failure and safety hazards.

Develop a storage plan. Knowing where items will be stored helps you choose the right mix of base cabinets, wall units, and tall storage. Ensure shelving is adjustable and strong enough to handle its intended load without sagging. Our detailed casework guide for new lab builds provides more specifics.

Step 3: Plan for Systems Integration

Modern labs have complex utility systems. Your casework must accommodate plumbing lines, electrical outlets, data ports, and ventilation ducts. The layout needs to incorporate sink bases, gas turrets, and power outlets without compromising structural integrity.

Remember to account for specialty cabinets, such as those under fume hoods with specific ventilation needs. Proper planning ensures that service lines are accessible for maintenance while remaining safely concealed.

Step 4: Inspect Construction and Hardware Quality

The long-term durability of casework depends on its construction details. Look for solid panel construction and robust assembly methods. Pay close attention to the hardware, such as hinges, slides, and pulls, as these are common points of failure.

  • Hinges: Choose stainless steel five-knuckle or heavy-duty concealed hinges for the best defense against corrosion.
  • Drawer Slides: Full-extension, ball-bearing slides are essential for smooth operation and complete access to drawer contents.
  • Pulls: Select pulls that are easy to grab with gloves and made from a corrosion-resistant material.

Step 5: Evaluate Lifecycle Costs and Maintenance

Finally, look beyond the initial purchase price. Calculate the total cost of ownership, which includes installation, ongoing maintenance, and potential replacement costs. Phenolic casework may have a higher upfront cost than laminate, but its service life is significantly longer in demanding environments.

Its low-maintenance nature is a major advantage, typically requiring only cleaning with mild detergents. By balancing the initial investment against its durability and minimal upkeep, you make a sound financial decision for your lab.

Exhaust Snorkels for Labs: Source Capture, Selection, and Setup

Marketing Manager

When working in a lab, you often deal with fumes, dust, or vapors. An exhaust snorkel is a critical tool for safety. It is a flexible, articulated arm designed to capture airborne contaminants at the source.

This method is called localized exhaust ventilation (LEV). The goal is to stop contaminants from reaching your breathing zone or spreading into the lab. It is not a full fume hood. Instead, it is a targeted solution for smaller tasks on an open benchtop. It offers great flexibility and better energy efficiency.

What Are Exhaust Snorkels?

An exhaust snorkel is based on the principle of source capture. This approach is more effective and energy efficient than general room ventilation. Diluting contaminants after they spread is less effective.

By placing the snorkel’s hood near the emission source, you create a focused airstream. This stream immediately pulls harmful substances away from technicians. Think of it like using a vacuum nozzle directly on a spill instead of a fan from across the room. The targeted method is better.

How Snorkels Differ from Fume Hoods

People often ask about the difference between a snorkel and a fume hood. Both are important ventilation tools, but they have different jobs. A fume hood is a large, enclosed box. It provides a physical barrier for experiments with large volumes of hazardous materials.

An exhaust snorkel offers flexibility. It is the perfect tool for tasks on an open bench that produce smaller, localized fumes or particles. Because it only pulls a small amount of air from the room, it is a more energy conscious choice for the right applications. A detailed localized exhaust snorkel overview can help you see how these systems fit into a total lab safety plan.

How to Choose the Right Exhaust Snorkel

A lab technician carefully adjusts an exhaust snorkel arm over a scientific instrument on a workbench.

Selecting the right exhaust snorkel requires a careful process. You must match the equipment to the specific hazards and your team’s workflow. Following a step-by-step approach ensures you choose a snorkel that meets safety and practical needs.

1. Define the Hazard Profile

First, identify what you need to capture. The type of contaminant is the biggest factor in your choice of material and design.

  • Chemicals and Solvents: If you work with acids, bases, or volatile organic compounds (VOCs), you need a chemical resistant snorkel. These are typically made from polypropylene to prevent corrosion.
  • Particulates and Dust: For fine powders or dust, a standard snorkel is usually sufficient. The main concern is having enough airflow to capture particles effectively.
  • Static Sensitivity: In labs with sensitive electronics, static discharge can damage components. An ESD safe snorkel uses conductive materials to ground static electricity safely.

2. Assess Capture Point Geometry

Next, look at your workstation’s physical layout. The snorkel must reach the fume source without blocking the user or other equipment.

Measure the distance from the mounting point to all possible work spots. Snorkel arms have a specific maximum reach, so ensure your choice can cover the entire work zone. More joints in the arm provide more flexibility for precise positioning.

3. Calculate Required Airflow (CFM)

Airflow, measured in cubic feet per minute (CFM), determines performance. This number relates to capture velocity. Capture velocity is the air speed needed to pull contaminants into the ductwork.

The required CFM depends on the contaminant and the process. Heavier particles or fumes released with force require higher capture velocity. As a rule, place the capture hood as close as possible to the source, usually within one duct diameter. A ventilation engineer can help determine the exact CFM your application needs.

4. Select the Mounting Configuration

How the snorkel attaches to your lab affects usability and stability.

  • Ceiling Mount: Ideal for labs with high ceilings or when bench space is limited. This option offers the greatest range of motion.
  • Wall Mount: Saves space and provides a stable base for benches against a wall.
  • Bench Mount: The most stable option for a fixed workstation, but it takes up some bench space.

Your choice depends on your lab’s construction, exhaust duct locations, and workflow flexibility.

5. Choose Necessary Accessories

Finally, select accessories to optimize the snorkel for your tasks. The capture hood is the most critical accessory.

  • Dome or Bell Hoods: Best for capturing fumes that rise, like from heated processes.
  • Flat Screen Hoods: Use these to capture fumes across a wider, flatter area.
  • Slotted Hoods: Designed to pull fumes horizontally.

Also consider add ons like airflow dampers. These let users adjust the CFM at their workstation. This is useful when multiple snorkels are running at once.

Comparing Exhaust Snorkel Materials and Features

The materials and design of an exhaust snorkel determine its safety, performance, and lifespan. A standard arm perfect for soldering fumes could fail quickly if exposed to acids. Understanding the core differences between the main snorkel types is essential.

Standard (Original) Snorkel Arms

The standard lab snorkel arm is a versatile choice for general purpose fume and dust capture. These arms have anodized aluminum tubes and polypropylene joints. They offer a balance of light weight and strength.

This design is a good match for non corrosive contaminants, such as:

  • Light dust from weighing powders
  • Soldering fumes
  • Mild solvent vapors
  • General odors

Chemical Resistant Snorkels

When processes involve aggressive chemicals, a chemical resistant snorkel for corrosives is necessary. These snorkels are made to withstand chemical attack. The tubes and joints are typically 100% polypropylene. This plastic is known for its resistance to acids, bases, and many solvents.

These are the clear choice for applications like:

  • Acid digestions
  • Work with volatile organic compounds (VOCs)
  • Sample prep with strong solvents

ESD Safe Snorkels

In electronics manufacturing and repair, static electricity can destroy sensitive components. An ESD safe extraction arm for electronics work eliminates this threat.

These snorkels are built with conductive materials and are connected to a ground point. This allows any static charge to dissipate safely. This feature protects microchips and circuit boards from electrostatic discharge (ESD) damage.

Exhaust Snorkel Model Comparison

This table breaks down the key differences between the three main types of exhaust snorkels. Use it as a quick reference to compare specifications.

Snorkel Use Cases and Decision Scenarios

An ESD-safe exhaust snorkel is carefully positioned over a workbench where a technician is soldering a circuit board.

Theory and specifications are one thing. Seeing how snorkels perform in a working lab is another. These arms solve specific safety problems at the bench. A few common scenarios show why choosing the right snorkel is so important.

Scenario 1: Electronics Soldering Station

  • Challenge: Soldering creates harmful flux fumes and poses a risk of electrostatic discharge (ESD) to sensitive components.
  • Solution: An ESD safe snorkel. It captures fumes at the source while its conductive construction grounds static electricity.
  • Placement: Position the hood 4 to 6 inches above the solder joint. A stable bench mount is ideal for repetitive tasks.

Scenario 2: Small Volume Acid Titration

  • Challenge: Working with small amounts of acid on an open bench creates corrosive vapors that are an inhalation hazard.
  • Solution: A chemical resistant snorkel made from polypropylene. It will not degrade from exposure to acid fumes.
  • Placement: Place the hood near the beaker to create a zone of negative pressure that pulls vapors away from the user.

Scenario 3: Pharmaceutical Powder Weighing

  • Challenge: Weighing fine powders can create airborne dust that should not be inhaled. Air currents must be minimized to avoid disturbing sensitive scales.
  • Solution: A standard snorkel with a wide, bell-shaped hood.
  • Placement: Position the hood just above and behind the weighing station. This captures rising dust without creating turbulence near the balance.

Scenario 4: Art Restoration and Solvent Use

  • Challenge: Art restorers often use small amounts of solvents to clean artifacts. These tasks require precise control and fume capture in a non-traditional lab setting.
  • Solution: A standard snorkel with good articulation and a small, targeted hood.
  • Placement: A ceiling or wall mounted arm offers the most flexibility to position the hood near the artifact without touching it.

Scenario 5: University Teaching Lab

  • Challenge: A teaching lab has multiple workstations where students perform various experiments with mild chemicals or biological samples.
  • Solution: Multiple standard snorkels, perhaps one for every two students. They offer a cost effective way to provide source capture for general use.
  • Placement: A combination of ceiling and wall mounts can cover all stations without cluttering the benches.

Integrating Snorkels with Benches and Casework

Proper installation is a critical final step. A snorkel must be integrated into your lab’s space and ventilation system. This requires planning for ductwork, your building’s exhaust system, and snorkel placement. Good integration results in a clean workspace with effective source capture.

Mounting Options for Lab Benches

The mount type directly impacts reach, stability, and bench space.

  • Ceiling Mounts: Best for high ceilings or when bench space is limited. They provide maximum range of motion.
  • Wall Mounts: A good middle ground that saves bench space while offering a stable base.
  • Benchtop Mounts: Offer the best stability for dedicated workstations but take up a small footprint.

Ductwork and System Connection

The snorkel arm must connect to your building’s main exhaust system. Ducting design is important for proper airflow.

The length of the duct run and the number of bends add static pressure. This is the resistance the exhaust fan must overcome. Too much static pressure can reduce the snorkel’s CFM and capture velocity. An HVAC engineer can help balance the system to ensure each snorkel gets its designed airflow. This ensures proper function for all hoods and enclosures in the facility.

Maintenance and Lifecycle Guidance

An exhaust snorkel is a critical safety device that requires regular maintenance. A simple inspection schedule ensures its performance and extends its life. Consistent upkeep prevents small issues from becoming major safety failures.

Routine Inspections and Cleaning

A visual and physical check should be part of your lab’s safety walkthrough.

  • Check Arm Tension: The arm should move smoothly and stay in position. If it drifts, adjust the tension according to the manufacturer’s guide.
  • Inspect Seals: Look at the O-rings and seals in the joints for cracks or wear. A degraded seal can cause air leaks and reduce suction.
  • Clean the Capture Hood: Keep the hood free of dust and residue. A mild detergent and water usually work. For a chemical resistant model, ensure the cleaning agent is compatible with polypropylene.

Periodic Airflow Verification

At least once a year, you should verify the system’s airflow. This ensures it still meets its original design specifications for capture velocity.

This task is typically done by an EHS professional using a calibrated anemometer. They measure air speed at the hood’s face and calculate the airflow in CFM. Low numbers could indicate a clog, a fan issue, or a leak. Keeping records of these checks is a key part of any lab safety program and is fundamental to overall fume hood safety.

Frequently Asked Questions About Exhaust Snorkels

What is the main difference between an exhaust snorkel and a fume hood?

A fume hood is a large, enclosed cabinet that provides a physical barrier for hazardous work. An exhaust snorkel is a flexible arm for capturing contaminants at the source on an open bench. Snorkels are for smaller, localized tasks and are more energy efficient.

How do I calculate the right CFM for my application?

The correct CFM (Cubic Feet per Minute) provides enough capture velocity to pull contaminants into the snorkel. The required velocity depends on the hazard. An industrial hygienist or ventilation engineer can help you determine the precise CFM needed for safety and compliance.

Can snorkels be used in cleanrooms?

Yes, but they must be made from non-shedding materials like stainless steel or electropolished aluminum. The system must capture contaminants without disrupting the room’s laminar airflow.

What chemicals can a chemical resistant snorkel handle?

A chemical resistant snorkel is typically made from polypropylene. This material resists a wide range of acids, bases, and organic solvents. However, you should always check your specific chemicals against a polypropylene chemical compatibility chart to ensure safety.

What is the maximum reach of a snorkel arm?

Snorkel arms are available with a reach from about 3 feet to over 8 feet. Measure your workspace to ensure the arm can reach all emission sources. It is wise to choose a model with slightly more reach than you think you need for added flexibility.

Do I need a separate exhaust fan for my snorkel system?

Yes, in almost all cases. A snorkel arm is a passive component. It needs an external fan to create the suction required to pull air through the system. The fan must be sized correctly to handle the system’s static pressure and deliver the necessary CFM at the hood.

How should the capture hood be positioned for best results?

The capture hood should be placed as close to the emission source as possible. A good rule of thumb is within one duct diameter of the source. This maximizes capture efficiency and prevents contaminants from escaping into the workspace.

Are there any standards that govern exhaust snorkel performance?

Yes. Organizations like the American Conference of Governmental Industrial Hygienists (ACGIH) provide guidelines for local exhaust ventilation systems in their Industrial Ventilation Manual. These guidelines offer recommendations for capture velocities for different types of contaminants.

Biological Safety Cabinet Classes: Class I, Class II, and Class III Explained

Marketing Manager

Biological safety cabinets (BSCs) are enclosed, ventilated workspaces used in laboratories. They are engineered to protect the user, the work product, and the environment from hazardous biological materials. This protection is achieved through specialized airflow patterns and high-efficiency particulate air (HEPA) filters.

Choosing the correct BSC is critical for lab safety and research integrity. The decision depends on the specific biological agents, chemicals, and procedures used in your lab. Understanding the differences between the biological safety cabinet classes is the first step toward a safer, more compliant facility.

Key Takeaways

  • Class I cabinets protect the user and the environment but not the product inside. They are for low-to-moderate risk agents where sterility is not needed.
  • Class II cabinets protect the user, product, and environment. They are the most common type, with subtypes (A2, B1, B2) for different chemical use scenarios.
  • Class III cabinets provide the highest level of containment. They are fully sealed gas-tight enclosures for work with high-risk BSL-4 agents.

Class I Biological Safety Cabinets

A Class I BSC is the simplest type of cabinet. Its primary function is to protect the user and the surrounding lab environment from hazardous aerosols generated during a procedure.

The airflow is straightforward. Room air is drawn into the cabinet through the front opening, flows across the work surface, and is then exhausted through a HEPA filter. This inward airflow prevents contaminated air from escaping the cabinet.

However, a Class I cabinet offers no product protection. Unfiltered room air constantly flows over the samples. This makes it unsuitable for work that requires a sterile environment, such as cell culture. What Class I protects is the operator, making it useful for enclosing equipment like centrifuges or for procedures with low-risk agents where sterility is not a concern.

Class II Biological Safety Cabinets

Class II cabinets are the most common type of BSC found in clinical and research labs. They provide protection for the user, the product, and the environment. This three-way protection makes them the workhorse for most biological research.

These cabinets create an air curtain at the front opening to protect the operator. At the same time, HEPA-filtered air flows downward over the work surface to protect the samples from contamination. All exhausted air is also HEPA-filtered to protect the environment. There are several subtypes of Class II cabinets, with A2 and B2 being the most common. The main difference lies in how they handle airflow and chemical vapors. Our popular Airstream biological safety cabinet line includes these advanced options.

Class II, Type A2

The Class II A2 airflow and applications are suited for most standard microbiological work. In a Type A2 cabinet, about 70% of the air is recirculated back into the work area through a HEPA filter. The other 30% is exhausted through another HEPA filter, either back into the lab or through a thimble connection to the building’s exhaust system.

These cabinets are designed for work with biological agents in the absence of volatile or toxic chemicals. Only trace amounts of chemicals can be used, as the recirculated air could expose the user to chemical fumes.

Class II, Type B2

A Type B2 cabinet is often called a “total exhaust” cabinet. It is hard-ducted directly to an external exhaust system and vents 100% of the air outside after HEPA filtration. No air is recirculated within the cabinet or the lab.

This design makes it the proper choice when a B2 cabinet makes sense: for work involving both biological agents and significant amounts of hazardous or volatile chemicals. The total exhaust system ensures that no chemical vapors are returned to the workspace, protecting the user. Understanding the differences between a BSC and a chemical fume hood is key to making this distinction.

Class III Biological Safety Cabinets

A scientist wearing full protective gear operates within a Class III biological safety cabinet, handling materials through attached gloves.

alt=’A user manipulates materials inside a sealed Class III glovebox, wearing heavy-duty arm-length gloves attached to the unit.’

For work with the highest-risk pathogens (Biosafety Level 4), a Class III cabinet is required. These units provide the maximum level of containment. A Class III BSC is a completely sealed, gas-tight enclosure maintained under negative pressure.

The operator works through heavy-duty gloves attached to ports on the cabinet, providing Class III glovebox level containment. This creates a total physical barrier between the user and the hazardous agent. All air entering the cabinet is HEPA-filtered, and all exhausted air passes through two HEPA filters in series before being discharged outside. This design is similar to a glovebox fume hood but is built specifically for biological hazards.

Comparison of Biological Safety Cabinet Classes

This table provides a side-by-side comparison of the key features, applications, and considerations for each BSC class.

Feature Class I Class II, Type A2 Class II, Type B2 Class III
Airflow Pattern Inward flow, no recirculation. 70% recirculated, 30% exhausted. 0% recirculated, 100% exhausted. Sealed system under negative pressure.
Product Protection No Yes Yes Yes (Maximum)
Personnel Protection Yes Yes Yes Yes (Maximum)
Typical CFM & Filtration Single HEPA on exhaust. CFM varies. HEPA on supply and exhaust. Thimble option. HEPA on supply and exhaust. Hard ducted. Double HEPA on exhaust. Hard ducted.
Best Applications Housing equipment, procedures with non-sterile agents. Cell culture, microbiology with no volatile chemicals. Work with biologicals and volatile toxic chemicals. Work with BSL-4 agents (e.g., Ebola virus).
Considerations Does not protect the sample from contamination. Not for use with significant amounts of chemicals. Requires dedicated building exhaust system. Complex setup, limited user mobility.

How to Choose the Right BSC Class: A 5-Step Checklist

Selecting the right BSC is a critical safety decision. Follow this step-by-step checklist to ensure your choice aligns with your lab’s specific needs.

  1. Assess Biological Risk: First, identify the Biosafety Level (BSL) of every agent you will handle. BSL-1 agents require basic containment, while BSL-4 agents demand a Class III cabinet. This assessment is the foundation of your decision.
  2. Determine Need for Product Protection: Next, decide if your work requires a sterile environment. If you are working with cell cultures or other sensitive materials, you need product protection. This immediately rules out Class I cabinets.
  3. Evaluate Chemical Use: Then, list all chemicals you plan to use inside the cabinet. If your protocol involves volatile toxic chemicals or radionuclides, a Class II, Type A2 cabinet is not appropriate. You must select a Class II, Type B2 or Class III cabinet.
  4. Review Facility Requirements: After that, analyze your lab’s infrastructure. Does your HVAC system support the exhaust requirements of a ducted B2 cabinet? Confirm available space, power, and utility connections before making a purchase.
  5. Consult with EHS and Biosafety Officer: Finally, always consult with your institution’s Environmental Health and Safety (EHS) department. They must review and approve your choice to ensure it meets all safety regulations and institutional policies.

5 Common Scenarios for Selecting a BSC

  • Scenario 1: University Cell Culture Core Facility.
    • Workflow: Researchers work with non-infectious human and animal cell lines (BSL-2). No volatile chemicals are used.
    • Decision: A Class II, Type A2 cabinet is the standard choice. It provides the necessary product protection to prevent contamination and protects users from potential biohazards.
  • Scenario 2: Clinical Microbiology Lab.
    • Workflow: Technicians identify bacterial and fungal cultures from patient samples (BSL-2).
    • Decision: A Class II, Type A2 is also ideal here. It protects staff from infectious aerosols and maintains the sterility of the cultures.
  • Scenario 3: Pharmaceutical Quality Control Lab.
    • Workflow: A procedure requires handling a BSL-2 agent while using small, defined quantities of a volatile solvent like methanol.
    • Decision: This workflow requires a Class II, Type B2 cabinet. The total exhaust system is necessary to protect the operator from inhaling chemical fumes.
  • Scenario 4: Animal Research Facility.
    • Workflow: Staff are changing cages for rodents housed in a BSL-2 containment suite. The goal is to contain allergens and potential pathogens.
    • Decision: A Class I cabinet is often used for this task. Product protection is not needed, but personnel and environmental protection from allergens and aerosols are crucial.
  • Scenario 5: High-Containment Government Lab.
    • Workflow: Scientists are researching emerging infectious viruses like Ebola or Marburg (BSL-4).
    • Decision: This work mandates a Class III cabinet. The gas-tight, sealed environment provides the absolute highest level of protection against deadly pathogens.

Installation, Maintenance, and Certification

Proper installation is essential for a BSC to function correctly. The cabinet must be placed away from high-traffic areas, doors, and air vents to avoid disrupting its protective air curtain. Ducted cabinets, like the Class II B2, require professional integration with the building’s HVAC system. Casework, benches, and service utilities must be planned to ensure ergonomic access and safe operation.

Regular maintenance and certification are mandatory. A certified technician must test and verify the cabinet’s performance at least annually. This includes checking airflow velocities, HEPA filter integrity, and alarm functions. Keeping detailed records is a critical part of lab compliance. Following a proper BSC certification and annual testing schedule ensures the cabinet provides consistent protection.

Frequently Asked Questions (FAQs)

1. What is the main difference between a Class I and Class II BSC?
The main difference is product protection. A Class I BSC protects the user but not the sample. A Class II BSC protects the user, the sample, and the environment.

2. Can I use a Bunsen burner inside a BSC?
It is strongly discouraged. The open flame disrupts the cabinet’s internal airflow, which can compromise both user and product protection. The heat can also damage the HEPA filters.

3. How often do HEPA filters need to be changed?
HEPA filters typically last for several years but should be changed based on the results of annual certification tests. A technician will perform a test to determine if the filter has become too loaded with particles to maintain proper airflow.

4. What is the difference between a HEPA and a ULPA filter?
A HEPA filter is at least 99.97% efficient at removing particles of 0.3 microns. An ULPA (Ultra-Low Particulate Air) filter is even more efficient, removing 99.999% of particles 0.12 microns in size. ULPA filters are often used in Class III cabinets or cleanrooms.

5. What does BSC certification involve?
Certification is a series of tests performed by a qualified technician to verify that a BSC is working correctly. It includes measuring airflow velocity, checking for HEPA filter leaks, and ensuring alarms are functional. It should be done upon installation and at least once a year after that.

6. Do I need a Class II A2 or B2 cabinet?
Choose a Type A2 if you only work with biological agents. Choose a Type B2 if your work involves both biological agents and more than trace amounts of volatile toxic chemicals. Always confirm with your safety officer.
