This device features a PTFE membrane which is ideal for chemically aggressive solutions, reagents and organic solvents. This lightweight unit is particularly suitable for protective vents and for in-line filtration and isolation applications. The 1 µm device features a polypropylene prefilter for use with heavily contaminated samples.
Features and Benefits
- Solvent resistant membrane
- Chemical resistant housing
- Hydrophobic PTFE membrane
- Autoclavable (multiple times)
- Integrity-testable (bubble point or water breakthrough pressure ‘in situ’ methods)
- Biosafe
- Lightweight (11.5 g for Polydisc and 17.9 g for ReZist); avoids the collapsing of tubing which can be caused by heavy filter devices
Applications
- Pharmaceutical: vents and in-line applications
- Biotech: sterile vents and exhausts for growth environments, in-line sterilization of gases
- Laboratory: clean or sterile gases. Filtration of solvents and reagents. Drying gases.
- Electronics: photoresists, solvents, gases for research
