Microlab Scientific’s 50mm Vent Filters are sterilizing filter for Venting and Liquid Solutions. It removes microorganisms, particles, precipitates, and undissolved powders larger than nominal pore size such as 0.22μm. The special construction allows minimal hold-up volume and particle shedding, making Vent Filters ideally suited for the critical needs of the pharmaceutical and biotechnology industries.
Features: Reusable, autoclavable, ideal for use with bioreactors and fermenters Have broad chemical resistance Large surface area provides greater throughput and permits higher air flow rates
Application: Sterile venting of carboys, filling vessels, fermentation tanks, bioreactors Venting of Small product or intermediates tanks Small volume venting and degassing Sterile gas purging of culture vessels Sterile gas delivery to instruments, incubators and culture vessels Protection of laboratory personnel from vacuum pump exhaust contaminants Filter low volumes of aggressive solvents and aqueous solutions Protect pump components from liquid damage by using between a pump and receiving vessel Chromatography solutions
