Tidi® Ultimate Lab Countertop Paper, 18 x 20 Inch

18 x 20 inch sheets offer versatile protection: Cushioning decreases the likelihood of breakage of glass labware while also absorbing spills of potentially hazardous liquids. Pebble-embossed side soaks up spills and residual liquids; one side has a polyethylene layer which serves as a barrier to liquids. There are 400 white, 18 x 20 inch flat sheets in a case.
