Ahlstrom's Polyshield® Fluid barrier is a super absorbent, pure cellulose paper with an impermeable polyethylene backing that absorbs splatters and spills, and protects work areas from contamination and damage by toxic, infectious, corrosive, radioactive or staining materials.

Polyshield's smooth, firm surface does not inhibit stability of bottles or tubes and allows recovery of dry spills. Liquid samples can be recovered by washing the absorbed spill from the inert surface with the appropriate buffer. Disposal is safe and easy and Polyshield ashes readily upon incineration.
