Polyshield Fluid Barriers
Ahlstrom’s Polyshield Fluid Barrier is a super absorbent, pure cellulose paper with an impermeablepolyethylene 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.

Extraction Thimbles
Ahlstrom‘s high purity cellulose extraction thimbles are most commonly used in Soxhlet extraction units for the separation of individual components from a mixture of solids and semisolids by solvent extraction. The use of a Soxhlet extractor provides a safe method of extraction with toxic or other noxious solvents. Ahlstrom extraction thimbles are recommended for the estimation of fats in food, analysis of lacquer and binder in paints, vitamin A and carotene extractions, and extraction of organic compounds from reaction mixtures. Thimble walls are approximately 1.5 mm thick and have been found to perform satisfactorily in applications requiring either a single or double wall thickness.
