TefloGas Filter Cartridges
Hydrophobic PTFE Membrane · Sterilizing Grade

TefloGas Filter Cartridges are composed of a hydrophobic PTFE membrane and a thick thermal-resistance polypropylene core. They are characterized by a high filtration area and non-metallic ion release and are easy to clean when compared to filters with a stainless steel core. As a result, they are highly recommended for air and gas sterile filtration of biological liquids and fermentation and pharmaceutical industries.



Features and Benefits

  • Inherently hydrophobic

  • Exceptionally high flow rates with low pressure drops
