Optiseal-M filters with Aervent membrane are 0.2 µm hydrophobic cartridges. They are designed for sterilizing applications, removing particles and microorganisms from gases and solvents. They are made with PTFE membrane and polypropylene components for broad application compatibility. Optiseal-M filters with Aervent membrane are designed to be used with Millidisk housings.
Each unit is 100% integrity tested during manufacturing to guarantee integrity.
The sterilizing grade rating is based on ASTM liquid bacterial retention challenge. In gases this filter will remove contamination down to 0.01 µm. Optiseal-M Aervent hydrophobic cartridges will remove particles and microorganisms from gases and liquids for low flow rates.
- Sterile tank venting
- Fermentation air applications
- Bioreactor inlet and outlet filtration
- Sterile process gases
Cartridges will also sterilize alcohol streams.
