|Aerex® 0.22 μm Hydrophobic Cartridge Filters|
|What is the difference between Aerex and Aervent?||Aervent cartridges have a 0.2µ PTFE membrane and are used in pharmaceutical applications where it is critical to use a phobic filter that has proven bacterial and viral retention capabilities. Common applications for Aervent are fermentation air applications, bioreactor inlet and outlet filtration and sterile process gases. Aervent filters have a liquid bacterial retention claim as well as a virus aerosol retention claim.
Aerex filters also have a 0.2µ PTFE membrane but they do not come with a liquid bacterial retention claim. Common applications for Aerex include bulk intermediate manufacturing and non-pharamaceutical applications such as industrial fermentation. Aerex filters do have a virus aerosol retention claim.
Aerex hydrophobic cartridges are sterilizing-grade filters manufactured from PTFE membrane and polypropylene components for broad chemical compatibility and low gravimetric extractables. Cartridges are 100% integrity tested during manufacturing to guarantee filter integrity and sterility assurance. The Aerex filter production process has been validated and the manufacturing plant meets ISO® 9001 standards.
Millipore's qualification of Aerex membrane filters includes a challenge regime designed to test virus and bacterial retention by three challenge mechanisms: aerosol, and grow through. Aerex filters have been validated to withstand at least 150 steam cycles at 145 °C, the equivalent of over two years use.
Aerex hydrophobic cartridges will remove particles and microorganisms from gases and solvents. In gases this filter will remove contamination down to 0.01 µm.
- Sterile tank venting
- Fermentation air applications
- Bioreactor inlet and outlet filtration
- Sterile process gases
Cartridges will also sterilize alcohol streams.
