Sterilizing-grade Durapore 0.1 µm and 0.22 µm Hydrophilic Cartridge Filters
A trusted name in the industry for over 25 years, 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.
Can Durapore 0.22 micron cartridges be used in the reverse direction?
» Answer
Durapore filters are bidirectionally supported. If the filter is inadvertently used in the reverse direction, a post-use integrity test will identify whether or not the filter cartridge was integral during processing. The specification for theis filter is > 50.0 psi for a water bubble point test and < 13.3 ml/minute per 10"element for a diffusion test. If the filter passes this test, no damage occured during use. Please note that the maximum allowable pressure specification is different in the reverse direction - 50 psid vs. 80 psid in the forward direction.
