Whatman Group offers Cellulose Acetate Membranes with Pure Cellulose Acetate. Whatman Group manufactures English mill making fine, handcrafted paper. The Cellulose Acetate Membranes with Pure Cellulose Acetate are hydrophilic making them suitable for aqueous and alcoholic media. The Cellulose Acetate Membranes are made from pure cellulose acetate making them suitable for biological and clinical analysis, sterility tests, and scintillation measurements. The Cellulose Acetate Membranes filters exhibit very low protein binding capacity. The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols and increased heat resistance. With high physical strength, the membrane filters can be used up to 180° C, are suitable for hot gases, and can be sterilized by all methods without sacrificing the integrity of the membrane.
