Polypropylene membrane filters are composed of pure polypropylene with absolute pore size ratings. Polypropylene 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, consis tent analysis results for sensitive ion chromatography applications while prolonging column life. Polypropylene filters are the preferred filter membrane for HPLC applications where the detection levels are below 230nm. Polypropylene filters also exhibit negligible protein binding which is essential for maximum sample recovery of critical, small volume protein samples. MicroScience polypropylene filters are available in 0.1, 0.22 and 0.45 micron pore sizes in all disc diameters.
