Used is in daily use in thousands of labs throughout North America. The material is a combination of Portland cement and fillers. Charcoal gray color. Colorlith has excellent heat, abrasion, and chemical resistance to a wide variety of chemical reagents.

Preferred in departments where tops are likely to be wet and dirty. Nevin stainless steel tops are seamless; sinks and backsplashes are welded into an integral unit. A raised marine edge keeps water on the top and prevents dripping on floors or cabinet fronts. The underside is sound deadened, and the top surface has a satin luster to minimize glare, resist scratches, and make maintenance easy.

Corian is a solid, non-porous homogeneous material composed of natural minerals and high-performance acrylic. Corian® is hard, stain resistant, and easy to keep clean. Because of its solid composition, color and pattern go all the way through. Surface abuse can usually be easily cleaned or repaired. Corian® is very stain resistant, but strong acids will damage the surface. Corian® should also be protected from high heat.

An attractive top material in low stress work areas, Nevin high-pressure plastic laminate tops are post formed; tops and backsplashes are seamless with a raised rolled front edge. Post forming construction is more sanitary; seams that harbor microorganisms are eliminated. A wide variety of colors is available.

Epoxy Resin tops are also in daily use in labs throughout North America. Epoxy resin is desirable for surfaces that must have excellent resistance to a wide variety of chemical reagents. Heat and abrasion resistance of epoxy resin is good to fair.
