Description and Specification for Lab Tenders
Sterility Test Apparatus.
The liquid sample is drawn through this sterile membrane filter to
concentrate any contaminating micro-organisms on the filter surface. The
sterility tests in these systems are done by the bacteria-retentive
membranes filter method. A 47 mm membrane filter is installed in a
suitable holder. After filtration is completed, sterile flushing fluid
is passed into the funnels, rinsing all sample residues through the
filters so that is cannot possibly inhibit growth of the retained
micro-organisms. After this, the filter is sectioned and aseptically
transferred to media for culturing. If growth is not visible after the
incubations period, the sample passes the text.
