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
