BorsoPTFE+

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.

Description

chevron-down

BorsoPTFE+ cartridges are manufactured using a highly hydrophobic ePTFE membrane. The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials (see graph). BorsoPTFE+ cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the ePTFE membrane make the BorsoPTFE+ filter cartridge particularly suitable for wet gas sterilizing applications, such as fermenter air feed.

The construction of the BorsoPTFE+ cartridge features design elements that allow for a higher membrane surface area, lower pressure drops, and incorporates a stainless steel core for greater mechanical strength when operated at higher temperatures.

Applications

BorsoPTFE+ ePTFE membrane cartridges meet the demanding filtration requirements of the pharmaceutical, biotechnology, food, and beverage industries. They are suitable for high-flow sterile venting and gas filtration applications, including the filtration of wet gases.

Typical applications include:

  • Sterile process gases: The supply of sterile gas for critical applications in the pharmaceutical, biotechnology, food, and beverage markets.
  • Sterile vents: The safe sterile venting of processing vessels in pharmaceutical, fermentation, and food and beverage processes.
  • Biotechnology: The sterile filtration of exhaust gases from biological fermenters.
  • Powder handling and tableting: The removal of ultrafine powder particles from compounding environments.
