Fluorofil™ Junior

ePTFE Membrane Cartridge Filters for Small-Scale Applications

Fluorofil™ Junior cartridges are manufactured using a highly hydrophobic ePTFE membrane and are designed for retrofitting into existing Junior-style housings. The enhanced ePTFE membrane offers exceptionally high gas flow pressure differentials (see graph).

Features and Benefits

  • Guaranteed microbial ratings in a liquid challenge
    Fluorofil™ cartridges are validated for bacterial removal in liquids in accordance with PDA, HIMA guidelines and ASTM F838-05, with a log reduction value >7. This test is stringent in comparison to an airborne particulate challenge test.

Applications

Fluorofil™ Junior ePTFE membrane cartridges meet the demanding filtration requirements of pharmaceutical, semiconductor and fine chemical manufacturers. They are suitable for a wide range of small-scale sterile venting and gas filtration applications, including the filtration of wet gases. They can also be used for the small-scale fine filtration of aggressive chemical solutions including acids, alkalis, solvents and etchants.

  • Sterile vents
    The safe sterile venting of processing vessels in pharmaceutical, fermentation, and food and beverage processes.
  • Small-scale sterile process gases
    The supply of sterile gas for critical applications in the pharmaceutical, biotechnology, food and beverage markets.
  • Small-scale fine chemicals and solvents
    The removal of submicronic particles from processing chemicals and solvents.
  • Small-scale photoresists and developers
    The microfiltration of photoresists and developer solvents, susceptible to contamination and precipitation during manufacture, storage and processing.
