Where It's Used

Applications & Industries

Chemicals & sanitising agents

Tested against a list of acids, bases, solvents and oils. The ratings are listed on page 4 of the datasheet. Verify compatibility under actual process conditions before use.

Pharma chemicals →

Cold and hot WFI

0.1 to 1.0 µm PVDF with low extractables — autoclaved filter effluent meets USP <643> and <645> per WFI requirements after a UPW flush.

Pharma water →

Pharmaceutical & biological liquids

0.2 µm sterilising-grade PVDF for antibiotics, blood products, biological agents and ophthalmic solutions.

Pharma industry →

Bioburden reduction

The 0.45 µm grade serves bioburden reduction; diluted preservative solutions are a listed duty.
