BorsoPTFE

BorsoPTFE cartridges are manufactured using a highly hydrophobic ePTFE membrane. Available in 0.2 micron.

BorsoPTFE cartridges are recommended for sterile gas filtration and venting applications, such as fermenter air feed. 

Each BorsoPTFE cartridge is individually integrity tested using the Diffusive Flow and validated for bacterial removal in liquids in accordance with PDA, HIMA guidelines and ASTM F838-05, with a log reductionvalue >7.

Integrity testing

Each BorsonPTFE module of every cartridge is individually integrity tested using the diffusive flow test, which correlates to the HIMA and ASTM F838-05 bacterial challenge test. Non-destructive integrity test, such as pressure hold, Diffusive flow and Bubbel point, can be performed by costumers. Procedural details are available from Van Borselen Filter the Netherlands.
