Print PageWhatman Type WPP polypropylene membrane filters are highly durable, making them suitable for numerous applications in chromatography and biotechnology laboratories.
High chemical resistance to organic solvents including acetonitrile
Uniform strength, meaning the membrane will not crack, tear, break, or distort when picked up by hand or forceps
Temperature resistance results in an autoclavable polypropylene membrane
No need to pre-wet with cytotoxic wetting agents that could be extracted
Chemical resistance for degassing and other applications
Whatman polypropylene membrane filters from Cytiva are compatible with organic solvents, making them highly suitable for degassing, especially acetonitrile, and HPLC mobile phase filtration.
In addition to use as a degassing membrane, these polypropylene membrane filters can be used as a support for cell growth, for filtration of media, or for sterilization of tissue culture media, pharmaceuticals, and other solutions used in biological work.
Looking for a filter paper, membrane filter, or syringe filter? Let whatman help you find the optimal filter for your needs to ensure reliable analysis.
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.
