Polypropylene(PP) membrane filters are composed of pure polypropylene with absolute pore size ratings. These filters offer broad chemical compatibility allowing its use with aqueous and organic solvent samples. The polypropylene filter has extremely low extractable levels designed to provide accurate, consistent analysis results for sensitive ion chromatography applications while prolonging column life.

Polypropylene(PP) membrane filter is the preferred filter membrane for HPLC applications where the detection levels are below 230 nm. The filters also exhibit negligible protein binding, which is essential for maximum sample recovery of critical, small volume protein samples. Because of their hydrophobic nature, the polypropylene membrane are best suited for industrial processes such as gas filtration, chemical processes and photo-resist production as well as for application in the automotive industry. Since polypropylene is a pure hydrocarbon material, there are no disposal problems relating to halogen content with PP membrane in contrast with other hydrophobic membranes such as PVDF or PTFE.
