Sterile Gas PTFE Membrane Filters
When validated membrane retention is required for sterile gas or vent applications
Our SurePore Highflow and SurePore Sterile Gas PTFE membrane filter ranges utilize a hydrophobic PTFE membrane renowned for its exceptional flow capacity. This feature ensures minimised clean differential pressures and prolonged service life. The SurePore Highflow cartridge hardware is engineered with wide bore polypropylene core and endcaps to increase cartridge flow and reducing cartridge differential pressure.
