ZTEC P Sterilizing Grade membrane cartridges are validated
for complete bacterial retention to yield product sterility in
biopharmaceutical final filtration applications. The naturally
hydrophilic and low protein binding characteristics of
polyethersulfone membrane ensure maximum transmission
of active ingredients making it ideal for a wide range of
pharmaceutical and biological liquid applications, including
the filtration of therapeutics, vaccines, antibiotics, bulk
pharmaceutical and other critical biotechnology products.
The double-layer PES 0.2 micron membrane filters are
manufactured in a cleanroom environment, and integrity
tested before shipment to assure consistent performance
and quality.
* The ZTEC P Membrane filter cartridges come standard with Silicone Seals on this site, however, we can also provide, Buna-N, EPDM, Viton and Teflon Encapsulated. Please send us a Request for Quote if you require other seal options.
