PTG Series Filter Cartridges feature hydrophobic polytetraflu-oroethylene (PTFE) membrane which offers excellent chemical compatibility and is an ideal choice as an air/gas vent filter. Specialty-grade polypropylene hardware and support layers offer enhanced resistance to oxidation. Is well-suited as an air vent filter for fermentation processes. Integrity testable by water intrusion (WIT).
Features
- Absolute 0.2µm filtration efficiency.
- 100% integrity tested.
- Receives a final rinse with 18MΩ ultrapure water to assure cleanliness.
- Excellent chemical compatibility.
- Tolerates pH 1 to 14. Hydrophilic membrane resists wetting.
Applications
- Sterile process air
- Aseptic packaging
- Tank air vents
- Fermentation process feed air
- Compressed gases
- Tolerates aggressive fluids: solvents, strong acids, & bases
