Disposable Vent Filter


Disposable vent filters or called gamma stable filters ,gamma compatible vent filters ,are consist of 0.2μm hydrophobic PTFE filter media,features bacteria retention for air venting and gas filtration.Inherently hydrophobic characteristic and high porosity makes the filters perfect resistance to particulates,bacteria and water while with high air/gas permit under very low differential pressure.Stepped hose barb connectors make them very flexible to connect with different size tubes.Very light weight can prevent tubes from bending.They can be either gamma irradiated or autoclavable,which are widely used in single use system and assembling,such like bioreactor,fermenter,cell flasks,carboys etc.
