BorsoPTFE+

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 makes the BorsoPTFE+ Plus filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed.

The construction of the BorsoPTFE+ cartridge has design features that allow 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 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: 

• Sterileprocess 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 tabletting
  The removal of ultrafine powder particles from compounding environments.
