SPP units contain Polypropylene (PP) membranes. Due to their broad chemical compatibility, these CHM® ready-to-use syringe filters can be used with aqueous and organic solvents. They have low extractable levels to provide accurate and consistent analysis results for sensitive ion chromatography applications. These polypropylene syringe filters are used in HPLC where detection levels are below 230 nm. They are supplied in two pore sizes 0.2 and 0.45 μm, and in two diameters 13 and 25 mm.
