Type of Laboratory Worktops & Their Selection Criteria

WORKTOP MATERIALS

A worktop is constructed of a wide range of materials. Factors such as material of construction, durability influence the cost of the worktops. Common worktop materials include:

• Natural stones
• Wood
• Stainless steel
• Plastic laminate
• Epoxy resin
• Phenolic resin
• Ceramics

CHOOSING A LABORATORY WORKTOP

Depending on the need, every laboratory has a choice of which type of worktop is best suited for them. Every lab planner must factor in the type of lab and the nature of experiments carried out, to select the worktop. The most important factors to consider are:

• Chemical resistance
• Abrasive resistance
• Heat resistance
• Impact resistance
• Moisture resistance
• Bacteria
• Type of use
• Furniture style
• Costs

While choosing a laboratory worktop it should be considered that a high-quality laboratory worktop should be selected that will provide the best return on investment. For the best return on investment, we will have a closer look at different worktops that are highly recommended for the best quality.

TYPES OF WORKTOPS

Epoxy Resin Lab Worktop

Epoxy resin is one of the most familiar and practical materials for lab use. Epoxy resin is well suited under harsh and extreme conditions. With many applications, epoxy is extremely compatible with fixed casework. Since the cabinetry isn’t intended to be moved, the worktop seams are often filled and joined to form a more monolithic surface. The thickness of epoxy worktops is one inch, which is very heavy. One inch thickness of epoxy resin weighs 11 pounds per square foot. Epoxy resin is formed from the mixing of different compounds in the liquid form and then poured into molds to cure and harden. Most commonly, epoxy in labs is in black. The salient features of epoxy resin are that it is heat resistant, bacterial resistant, corrosive resistant, chemical resistant, and flame retardant. It is easy to clean and maintain.

Phenolic Resin Worktops

Phenolic Resin is another worktop material which has been around for decades. Phenolic resin is lighter as compared to epoxy resin. Multiple layers of partially recycled paper are soaked into phenolic resin, and then placed under extreme heat. After that it appears as a solid material. The top of the layer has different colors while the core is typically black. Lab planners usually prefer monochromatic top. One inch thickness of phenolic resin weighs 7.2 pounds per square foot. The features of phenolic resign include bacterial resistant, chemical resistant, moisture resistant, moderate to high corrosive resistance, continuous heat exposure up to 350 °F and scratch resistance. It is mainly used in biological, chemical, clinical, and analytical labs.

Stainless Steel Worktops

Stainless Steel worktops are best in hygienic and anti-microbial properties. It is made up of chromium and nickel that protects from rust and corrosion and makes it heat resistant. Commonly used in biomedical labs, pharmaceutical labs, food testing labs, and hospitals. It has a non-porous surface. It can handle high temperatures above 1500 °F. It is easily cleanable and long-lasting.

Chemical Resistant Laminate Worktops

Chemical Laminate worktop is made by applying a synthetic resin over a decorative surface paper which is attached to the core of the kraft paper coated with phenolic resin that gives a decorative worktop that is highly resistant to chemicals. The heat exposure is up to 275°F. It is preferred in those labs where the results depend on non-contamination like in dental labs, pathology labs, urology labs, photographic darkrooms, and product testing labs.

Wood Worktops

Hardwood surfaces comprise rock maple that is sturdy and long-lasting. True woods are made with the end grain of the wood by gluing together smaller woodblocks. It has poor moisture resistance and bacterial resistance. It gives a warm and rich look. It is mostly used in mechanical labs.
