PTFE Membrane Filters

, PT series, are specially manufactured for the bio-pharma, beverage, and fine chemical industries to provide reliable filtration. Its design benefits in the complete removal of bacteria and other undesired particles, even in the presence of humidity and moisture.

The PTFE Membrane Filters are ideal for filtration of solvents in sterile API manufacture, fermenter inlet air and exhaust venting, and sterile venting of tanks and autoclaves. The PTFE Filters have a 0.2 micron

PTFE Filters

membrane validated for absolute bacterial retention, with the challenge data correlated to water intrusion testing.
