Protects lab and prep area work surfaces from spills, stains, and wear. Makes cleanup easy since the mat can simply be gathered up and disposed of-spill and all! Mat consists of a plastic-backed absorbent paper. The absorbent upper layer traps water, dye, and corrosive chemical(s), but won't allow liquids to soak through. The surface is ribbed to hold the lab vessel slightly above the surface. The plastic backing makes the mat non-skid. This mat material is 20" wide and is packed in a dispenser box containing a 50-foot roll. Pull the required length from the dispenser and, using scissors, cut off the amount you need.
