PTFE Membrane Filter Cartridges For Pharmaceutics

1. Product Description

   PTFE Membrane Filter Cartridges are sterilizing grade filters manufactured with highly retentive hydrophobic polytetrafluoroethylene (PTFE) membrane.

  The cartridges are designed for critical filtration of aggressive solvents and as compressed gas and vent filters. Each cartridge is individually tested using bubble point method before it is released from manufacture.

   The PTFE Membrane Cartridge in an all-polypropylene construction provides excellent chemical compatibility and superior flow per surface area as compared to other membrane cartridges.
