November 19, 2025November 19, 2025 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.

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.

A 5-Step Checklist for Selecting Phenolic Casework

alt=’A checklist being reviewed for selecting laboratory phenolic casework’

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.

When outfitting a lab, your choice of casework directly impacts safety, workflow, and your budget. Let’s compare how Laboratory Phenolic Casework performs against painted steel, stainless steel, and wood or laminate.

Phenolic vs. Painted Steel

Painted steel is a strong and cost-effective option for many labs. However, its painted surface can chip or scratch, exposing the steel underneath to moisture and chemicals. This can lead to rust and corrosion over time.

Phenolic resin, in contrast, has a solid composite structure. It is non-porous and will not rust or delaminate, making it a better choice for labs with high humidity or frequent chemical exposure.

Phenolic vs. Stainless Steel

Stainless steel is the top choice for sterile environments, cleanrooms, and areas requiring high heat resistance. It is exceptionally durable and easy to sterilize. However, it is also the most expensive option.

Phenolic casework offers excellent chemical and moisture resistance at a lower price point than stainless steel. For many labs that do not require sterile conditions, phenolic provides a durable and more economical solution.

Phenolic vs. Laminate/Wood

Laminate and wood core casework are the most budget-friendly options upfront. They are suitable for dry labs and areas with minimal chemical use. However, they are highly susceptible to damage from moisture and harsh chemicals.

Water exposure can cause laminate to peel and the wood core to swell, leading to irreversible damage. Phenolic casework is impervious to moisture, ensuring a much longer lifespan in wet or humid conditions.
