The filtration media of Polytetrafluoroethylene cartridge is hydrophobic PTFE membrane.
Polyflo cartridgee bears excellent operation features, and its safety and thermal control specifications conform to the requirements of USP of the USA. Each polyflo cartridge has passed 100% integrity testing of bubble point and expanison flow so as to ensure to reach the bacterial retention requirements of USA HIME.
PTFE pleated filter cartridge Main Features:
1. Inherently hydrophobic more resistant to water intrision than commonly used PVDF membrane.
2. Withstand shocks, back pressures and repeated sterilizations.
3. 100% bacterial retention and effective filtration to 0.02um pastical (in gas).
4. constructed of two materials PTFE and PP to meet high standards of pharmaceutical industry.
PTFE pleated filter cartridge Applications:
1. Sterile tank vents
2. Sterile filtration of solvents: esters acetone, carbon tetrachloride, DMSO methanol, ethanol and isopropanol.
3. Sterile filtration of compressed gases: air, nitrogen, fermentation bioreactor feed.
