Description
Compatibility

Whatman cellulose acetate membranes are made from pure cellulose acetate making them ideal for biological and clinical analysis, sterility tests and scintillation measurements.

Cellulose acetate membrane filters exhibit very low protein binding capacity. They are hydrophilic making them suitable for aqueous and alcoholic media.
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 180º C, are suitable for hot gases, and can be sterilized by all methods without sacrificing the integrity of the membrane.

Guide to…Membrane Filter Properties

Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate.
