Lab Casework Material Selection by Lab Type: A Buyer’s Guide

October 2, 2026October 9, 2026 Labs USA Team

A facility manager gets told to “order new lab casework” and opens a catalog with dozens of cabinet lines. The hard part is not the door style. It is matching each room to the chemicals, water, cleaning routine and wear that the cabinets will face every day for years.

This guide is for lab managers, facility teams, buyers, architects and contractors planning a new lab, a renovation or a refresh. The main idea is simple: pick the casework material room by room, not building by building. Start with the lab type, then choose the cabinet material and the work surface together.

Why Lab Casework Material Selection by Lab Type Matters

Picture a contractor waiting on a casework decision before rough-in. Purchasing has found a cheaper cabinet. The finish schedule says nothing about disinfectants or wash-downs. The person signing the order may never touch the chemicals at the bench. If the cabinet fails at an edge or joint two years later, replacing it shuts down the room and costs far more than choosing the right material up front.

A general research room, a pharma processing area, a university teaching lab and a vivarium each face a different mix of chemicals, humidity, cleaning and impact. A cabinet that works fine in a dry write-up area can be a poor choice next to a sink or in a room that gets wiped with disinfectant several times a day.

The Scientific Equipment and Furniture Association (SEFA) gives everyone a shared vocabulary. It publishes a separate lab-grade casework standard for each material family: SEFA 8M for metal, SEFA 8W for wood, SEFA 8PL for plastic laminate, SEFA 8PH for phenolic and SEFA 8P for polypropylene. You can see the current editions on the SEFA standards page. Each standard covers tests such as cabinet load and, for finishes, chemical resistance. Our guide to SEFA standards for laboratory furniture explains how to use them in a spec.

Start with a room-by-room list

Before you ask for a quote, list every room and answer four questions:

• What chemicals are used or stored? Include acids, bases, solvents, stains, disinfectants and cleaning products.
• How much water reaches the casework? Note sinks, wet processes, hoses, wash-downs, humidity and likely spill spots.
• How is the room cleaned? A daily wipe-down is very different from repeated wet cleaning or sterilization.
• What must the casework carry? Note heavy instruments, carts, waste, stored supplies and access needs.

This list keeps new-build teams from paying for the toughest material in every room. It also helps renovation teams decide which cabinet runs can stay and which need to go. For wider project planning, see how labs find the right lab equipment and furniture.

The Four Factors That Decide the Material

Score each room against these four factors before you shortlist any material.

1. Chemical exposure

Chemical exposure is more than the reagent on the bench. Cleaning products, disinfectants, stains, waste containers and spills all reach cabinet faces, edges, joints and hardware.

Phenolic resin and stainless steel are strong starting points for broad chemical contact. Polypropylene fits acid storage and very corrosive spots. Painted steel works in most general labs, but deep scratches or harsh chemicals can break through the finish. Wood and laminate belong in dry, low-risk rooms.

Use the Safety Data Sheets (SDS) and your EHS team to check the real chemical list. A general material label does not prove a material will hold up to a specific reagent.

2. Moisture and humidity

Water is a daily fact in wet chemistry, analytical, aquatics, glass wash and wash-down rooms. It also shows up in rooms that seem dry until a sink, hose or mop cart changes the pattern.

Phenolic resin and stainless steel lead the list for rooms that stay wet. Wood and laminate tend to fail where water gets into joints and edge banding. This guide to lab casework materials and applications describes the same split between wet rooms and dry rooms.

3. Cleaning and sterilization

Ask how the room is actually cleaned, not just whether it is called “sterile.” Teams may use disinfectant wipes, repeated wet cleaning, heat or other methods. The casework has to handle those exact products without turning rough, porous or damaged.

Pharma, biotech, cleanroom and vivarium spaces need smooth, non-porous surfaces that clean easily. Stainless steel is the usual default where sterilization, hygiene and wash-down happen together. Phenolic can work in some of these rooms, but the final call should follow the facility’s cleaning protocol and EHS review.

4. Hygiene, impact and load

Contamination risk affects seams, corners, handles, undersides and storage access. A cabinet that does well in a dry teaching room can be a poor fit where staff must clean every surface often. Strength matters too. Carts hit cabinet fronts, students lean on counters and heavy instruments sit on tops for years.

Rule of thumb: If cleaning is frequent, harsh or wet, move the spec toward stainless steel or phenolic. A finish upgrade on the wrong material is not a substitute for the right material.

Comparing Painted Steel, Stainless, Phenolic, Wood and Polypropylene

Each material family solves a different problem. Painted steel is the all-around workhorse. Stainless steel is for hygiene, water and sterilization. Phenolic handles wet and chemical-heavy work. Wood and laminate suit dry, low-risk rooms. Polypropylene is a specialist choice for corrosive storage.

Use the table below to screen options. It is not a chemical compatibility approval. Confirm the exact reagent, strength, temperature, contact time and cleaning product before you finalize.

Material	SEFA standard	Chemicals	Water	Cleaning	Best-fit rooms	Watch out for
Painted steel	SEFA 8M	Good for general lab use; depends on the finish	Good while the finish is intact	Easy routine cleaning	General research, QC, teaching, mixed-use labs	Chips and deep scratches expose bare steel
Stainless steel	SEFA 8M (metal)	Very good; depends on grade and chemical	Excellent	Excellent for frequent cleaning and sterilization	Cleanroom, pharma, biotech, vivarium, healthcare	Higher first cost; chlorides can attack Type 304
Phenolic resin	SEFA 8PH	Broad resistance	Excellent	Very good	Wet chemistry, histology, glass wash, humid rooms	Some strong acids and oxidizers; direct high heat
Wood or plastic laminate	SEFA 8W / 8PL	Limited; depends on finish	Limited	Fine in dry rooms	Dry teaching, write-up, office-like support rooms	Water at joints and edge banding
Polypropylene	SEFA 8P	Very strong against acids and bases	Excellent	Good	Acid storage, under-hood storage, corrosive wet benches	Use where needed, not as a default

Painted steel

Painted steel fits rooms that need strength, durability and good value. It is the usual choice for general research, QC and teaching labs, and it works in mixed-use rooms where the chemical list is under control. Lab-grade steel casework typically uses a baked powder coat finish, and SEFA 8M includes a chemical spot test for that finish.

The weak spot is the coating. A deep scratch, chip or harsh chemical can expose the steel underneath. Check sink areas, high-traffic fronts and storage under acid work. If the room gets frequent wash-downs or strong disinfectants, compare stainless and phenolic before you lock in painted steel. Browse our steel lab casework, or see a multi-room painted steel and epoxy resin fit-out we supplied in Birmingham, Alabama.

Stainless steel

Stainless steel leads when cleanability, sterilization, humidity and wash-down drive the spec. It is common in cleanrooms, pharma, biotech, vivarium and healthcare spaces.

Grade matters. Type 304 is the standard for most lab use. Type 316 adds molybdenum, which gives better resistance to chlorides, salts and some harsh corrosives. Rooms with bleach-based cleaning, saline or other chloride exposure are where 316 earns its higher cost. Our stainless steel casework page compares the two grades. Your facility team should still sign off on grade and chemical fit. For a head-to-head look, read painted metal vs stainless steel lab casework.

Phenolic resin

Phenolic is the stronger choice for rooms that stay wet, see broad chemical contact or run humid. It does not rust, and SEFA 8PH even includes a test that checks whether a floor-standing cabinet wicks up water. That makes it a good fit for wet chemistry, histology and glass wash rooms.

It has limits. Our phenolic lab casework page notes that concentrated sulfuric acid, chromic acid and some oxidizers can damage phenolic with long contact. Direct, long exposure to high heat or open flame is also a concern. Weber State University chose phenolic tops for a busy teaching lab; see the Weber State teaching lab project.

Wood and plastic laminate

Wood or laminate can make sense in dry teaching rooms, write-up areas and low-moisture support spaces. Wood also gives a warmer look in public-facing rooms. Keep them away from sinks, wash-downs and heavy chemical use. Water that gets into a joint or edge band swells the core, and that damage usually cannot be repaired.

Some institutions limit wood and laminate in certain labs. Stanford’s lab design guidelines, for example, say wooden bench tops are not right for biological labs because unfinished wood can absorb liquids, and that laminate bench tops are not suitable where seamless, easy-to-clean tops are required. This lab casework buying guide is a useful checklist for comparing first cost with long-term upkeep. To learn more, see how laboratory wood casework compares to steel or browse our wood lab casework.

Polypropylene

Polypropylene is a specialist. Solid polypropylene cabinets have no exposed metal to rust, which is why they often sit under acid work stations, inside wet benches or anywhere a corrosive drip is a daily event. SpaceX used one for exactly this reason; see our polypropylene base cabinet project in Hawthorne, California.

Use it where it is needed, not everywhere. Polypropylene is a plastic, so it is not a substitute for a rated flammable storage cabinet. Work with EHS on chemical separation, ventilation and fire rules. Stanford EHS, for instance, recommends not storing solvents under a fume hood. Our guide to furniture for cleanrooms and corrosive areas covers more options.

Matching Material to Lab Type and Work Surface

The fastest way to a sound choice is to give each room a default material, then adjust it for the real chemicals and cleaning. Do not pick a cabinet first and add a top later. The top can change how the whole station performs.

Use this table as a starting point. The final spec should follow your SDS review, EHS direction, local code and the surface maker’s compatibility data.

Lab type	Casework to start with	Work surface to start with	Why
General research and QC	Painted steel	Epoxy resin or phenolic	Durable, flexible and good value
University chemistry teaching	Painted steel	Phenolic or epoxy resin	Handles heavy daily use and student spills
Wet chemistry and analytical	Phenolic or stainless steel	Epoxy resin or phenolic	Water and chemical resistance
Pharma and biotech	Stainless steel	Stainless steel or epoxy resin	Cleanability, hygiene and sterilization
Cleanroom	Stainless steel	Stainless steel, or phenolic if the cleaning plan allows	Non-shedding, smooth, easy to disinfect
Vivarium and animal care	Stainless steel (Type 316 where chlorides are routine)	Stainless steel	Humidity, frequent wash-down and disinfectants
Clinical, pathology and histology	Painted steel, phenolic or stainless	Epoxy resin or phenolic	Stains, water and constant cleaning
Acid digestion and corrosive work	Polypropylene under the hood; phenolic or steel elsewhere	Epoxy resin or polypropylene	No metal for acid fumes to attack
Electronics and semiconductor	Painted steel or stainless steel	Surface chosen for ESD and static control	Static control and cleanliness
Dry teaching or write-up	Wood, laminate or painted steel	Laminate or another dry-use surface	Lower first cost where risk is low

Match the room, not the building

A pharma plant may need stainless steel in a processing area and painted steel in the QC lab next door. A university may use painted steel in chemistry rooms and wood in dry support rooms. Even one room can mix materials, with stainless at the sink and phenolic or steel along the rest of the run. Mixed specs control cost without putting wet or sterile rooms at risk.

For specific lab types, see our pharmaceutical lab furniture, environmental testing lab furniture and semiconductor cleanroom furniture pages. For cleanrooms, you can sketch the room in the cleanroom configurator.

Treat the work surface as part of the casework

Never approve a cabinet without reviewing the top, sink, backsplash, edges, joints and service cutouts. Stanford’s laboratory design guidelines say all bench tops and counters must be impervious to the chemicals used, and that tops should have a lip to help keep spills off the floor. Where a lab must be easy to decontaminate, the same guidelines call for seamless one-piece tops with sealed penetrations and a backsplash or cove at the wall. SEFA 3 covers lab work surfaces the way SEFA 8 covers cabinets.

Epoxy resin is a common pick for heavy chemical use and heat. Phenolic is lighter and very durable. Stainless steel suits wash-down and sterile work. Compare them in our epoxy resin vs phenolic countertop guide, browse laboratory work surfaces, and price tops in the lab countertop configurator.

A Five-Step Checklist for Specifying Lab Casework

Run this checklist before the cabinet schedule is set.

Step 1. List chemicals, cleaners and water exposure for each room

Write down the reagents, stains, solvents, disinfectants, sterilants, sinks, hoses, wash-down areas, humidity and likely spill spots in every room. Have EHS review the list and flag anything that needs special storage, separation or protection.

“General lab” is not a material spec. Two rooms with the same name can have very different needs. Record what touches the casework, how often it gets cleaned and where water will reach edges and joints.

Step 2. Rank hygiene, impact and load

• Hygiene: use smooth, cleanable materials where contamination control drives the room.
• Impact: favor steel where carts, equipment or students will bump cabinets.
• Load: note the weight and footprint of benchtop instruments, glassware and stored supplies.
• Access: confirm drawer, door, shelf and service access before the schedule is final.

A chemical-resistant panel cannot make up for weak construction or poor access. Judge the whole cabinet against daily use, not just its surface.

Step 3. Match the material family to the room

Use painted steel for general and teaching rooms, stainless steel for hygiene-focused or wash-down rooms, phenolic for wet and chemical-heavy rooms, wood or laminate for dry support rooms and polypropylene for targeted corrosive storage. Use the tables above as a starting point.

Step 4. Pair the cabinet with the top and check the site

Approve the cabinet, top, edge, joints, backsplash, sink, fittings and utility cutouts as one assembly. Confirm chemical compatibility and cleaning instructions for each part.

For renovations, start with the rooms that show damaged edges, swollen joints, failed finishes or tops that no longer match current chemicals. Field-measure walls, floors, utilities, doors and delivery routes before ordering. Existing conditions can change cabinet depth, sink location, fillers and the install sequence. Our laboratory renovation cost planning guide covers the budget side.

Step 5. Compare total cost, not sticker price

For each material that fits the room, add up purchase, installation, expected upkeep, facility changes and the cost of downtime if a run has to be replaced early. Then divide by the service life you expect in that room. A cheaper cabinet that fails at the sink in a few years can cost more per year than a tougher one. Ask suppliers for warranty terms in writing, and use the lab furniture cost guide for budget ranges.

Standards, Planning and Working With Labs USA

A lab-type-first process gives your team a clear reason for every material choice. Start with the SEFA standard for each casework family. Then coordinate the work surface, storage, utilities, accessibility and installation details. Where seated or accessible stations are needed, check ADA reach and knee clearance with your design team.

Do not approve a generic cabinet schedule and hope the finish fixes the problem. The material affects shop drawings, top details, sink cutouts, service openings, cleaning instructions and submittals. Ask for product data, SEFA test results, warranty limits and chemical resistance data before you issue a purchase order.

Labs USA supplies laboratory casework, work surfaces, fume hoods and lab furniture, along with layout help, specs, quotes and installation coordination. Send us a room list and we can return a room-by-room take-off that compares material families. Start early. Waiting until after rough-in can limit your material choices and cause layout conflicts, especially when one building holds several lab types.

Frequently Asked Questions About Lab Casework Materials

What is the best lab casework material?

There is no single best material. Painted steel suits most general labs. Stainless steel suits cleanrooms, pharma and wash-down rooms. Phenolic suits wet chemistry and humid rooms. Wood or laminate suits dry support rooms. Polypropylene suits acid storage. Match the material to each room’s chemicals, water and cleaning.

Can phenolic casework replace stainless steel in a cleanroom?

Sometimes, but not by default. Phenolic may work if it meets the room’s chemical, moisture, cleaning and contamination needs. Stainless steel is the safer starting point for repeated wash-down and sterilization. Confirm the choice with your cleanroom and EHS teams.

Should I choose Type 304 or Type 316 stainless steel?

Type 304 is the standard for most lab casework. Type 316 contains molybdenum, which improves resistance to chlorides and salts. Choose 316 where bleach, saline or other chloride exposure is routine, such as some vivarium and wash-down rooms.

Which material suits an autoclave or sterilization room?

Start with stainless steel when heat, moisture, sterilization and cleanability dominate. Review the full cleaning process, nearby tops, joints and equipment clearances before approval.

Can one lab use more than one casework material?

Yes. Many labs use painted steel in general areas, phenolic or stainless in wet zones and wood or laminate in dry write-up spaces. Mixing materials controls cost while protecting the rooms that need it.

Does SEFA affect the material choice?

Yes. SEFA publishes a lab-grade casework standard for each family: 8M metal, 8W wood, 8PL plastic laminate, 8PH phenolic and 8P polypropylene. These standards set test methods for things like load and finish chemical resistance. They do not replace your own chemical compatibility or EHS review.

Should a renovation replace every cabinet run?

Not always. Replace runs with water damage, failed finishes, poor chemical fit or a cleaning routine they cannot handle. Keep sound casework only after checking its material, size, utilities and future workflow.

How should buyers compare total cost?

Add purchase, installation, upkeep, facility changes, replacement needs and downtime. Divide that total by the service life you expect in that room instead of comparing sticker prices alone.
