TeflonFlow^® Filter Cartridges

Hydrophobic PTFE membrane · Sterilizing Grade

TeflonFlow^® Filter Cartridges are composed of hydrophobic PTFE membrane. It’s features include exceptional organic & inorganic corrosion resistance and inherently hydrophobicity. They are highly recommended for the pre-filtration and sterile nitration of strong solvents, highly corrosive fluids, strong oxidant fluids and critical air venting applications.

Features and Benefits

Inherently hydrophobicity
Broad chemical compatibility
High tolerance of aggressive acids and bases
High flow rates
Low extractables
100% Integrity Test

Typical Applications

Organic-based Antibiotic Liquids
API
Solvents
Air Venting
