A hydrophobic PTFE membrane filter candle. The hydrophobic membrane makes the filter ideally suited for the sterile filtration of gases and air.

BorsoPTFE+ cartridges are manufactured using a highly hydrophobic dual-layer ePTFE membrane. Each BorsoPTFE+ module in every cartridge is individually integrity tested using the Diffusive Flow Test, which correlates to the HIMA and ASTM F838-05 bacterial challenge tests.
