PP membrane disc filter

Product / Sample preparation

A hydrophobic membrane of pure polypropylene with broad chemical compatibility for aqueous and organic solvent samples and very low extractables. It is the preferred membrane for HPLC applications with detection below 230 nm, has negligible protein binding and also suits ion chromatography and gas filtration. It contains no halogens.
