Whatman cellulose acetate filter paper.

Whatman cellulose filters are manufactured from high quality cotton liners which have been treated to achieve a minimum alpha cellulose content of 98. These cellulose filter papers are used fro general filtration and exhibit particle retention levels down to 2 5 μm. They are hydrophilic making them suitable for aqueous and alcoholic media. Qualitative filter paper grades are based on various properties including particle retention thickness and weight.

Cellulose acetate membrane filters exhibit very low protein binding capacity. Additionally the highly heat resistant whatman cellulose acetate membranes can filter hot liquids and hot gases. A pore size of 0 2μm is the filter of choice for sterile filtration and clarification of aqueous solutions ph 4 8 such as nutrient media buffers and sera. 2 and are available in the common pore sizes.
