PFL Filter Cartridges are composed of hydrophobic PTFE membrane. Its features include exceptional organic & inorganic corrosion resistance and inherently hydrophobicity. They are highly recommended for the pre-filtration and sterile filtration of strong solvents, highly corrosive fluids and strong oxidant fluids.

Features and Benefits
Inherently hydrophobic
Wide chemical compatibility
High resistance of aggressive acids and bases
Low extractables
100% integrity test

Typical Applications
Organic-based antibiotic liquids
API
Solvents
