Sterlitech - Polypropylene Membranes
Sterlitech polypropylene 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. Sterlitech polypropylene 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. Sterlitech filters are available in 0.1, 0.22 and 0.45-micron pore sizes in a wide range of disc diameters.
