Gas Filtration Membranes


Cobetter hydrophobic ePTFE, with excellent gas flow rate and optimized water & bacterial resistance, is therefore used in a wide range of medical gas filtration applications, involving in-line insufflations, negative pressure suction filter, and drug preservation. 

The excellent retention efficiency of porous ePTFE membrane ensures microorganism & particle be controlled for sterile air exchange. A wide range of backing (support) materials support multiple sealing technologies.
