Ideal for use in air/gas and vent applications with proprietary, low- pressure-drop, hydrophobic polyvinylidene fluoride (PVDF) Emflon II membrane

• Emflon II membrane filters have a removal rating of 0.2 µm in liquid service and less than 0.02 µm particulate for air/gas applications.
• Connects easily to hoses of various sizes in-line or as a final filter.
• Light weight (< 27 grams), prevents crimping of tubing.
• Stable with gamma irradiation.
• Excellent for disposable systems.  Eliminates cleaning validation.

• Venting of bioreactors, fermentation tanks, and carboys.
• Sterile gas purging of culture vessels.
• Ideal for attachment to disposable systems that need to undergo gamma irradiation.
