General-purpose hydrophilic polypropylene membrane filter for most analytical filtration requirements. Compatible filter for both aqueous solutions and aggressive organic solvent solutions. Low protein binding. HPLC certified for low levels of UV-absorbing extractables. Maximum operating temperature 55°C (131°F).

Durapore sterilizing-grade 0.1 µm and 0.22 µm hydrophilic polyvinylidene fluoride (PVDF) membranes are low protein binding and provide sterility assurance, high flow rates and throughputs. The Durapore membrane contributes to clean processes due to low extractables, broad chemical compatibility, and its non-fiber releasing properties. Benefits
