TefloGas Filter Cartridges

Hydrophobic PTFE Membrane · Sterile Gas Filter

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

Quality Standards

Integrity Test correlates to ASTM F838-05 Bacterial Challenge Test (BCT)
Each filter is individually Integrity Tested (including Water Intrusion Test) prior to leaving the factory
Each filter is Fully Traceable with a unique serial number
