The membrane can then be aseptically transferred in the medium. The membrane filtration system is recommended for accommodating huge volumes of test material or when the test content has substances which may inhibit expansion of microorganisms, for instance antibiotics.
Sterility testing is often done working with amongst two techniques, membrane filtration or direct inoculation. For immediate inoculation, the test substance is just aseptically additional to inoculate the media. For membrane filtration, the test materials is passed through a dimensions exclusion membrane effective at retaining microorganisms.
