Ahlstrom Munksjö 4002-9250 LabSorb Fluid Barrier and Bench Protector. 92cm x 50-meter rolls are 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. A smooth, firm surface does not inhibit the 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, easy, and ashes readily upon incineration. 50-meter roll.
