Sterlitech
Polypropylene Membranes
*Note: Polypropylene is also available as a disposable capsule filter.
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.
