This apparatus made in
total 304 S.S
Pharmalab offers
complete systems for aseptically filtering liquid samples. 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. The liquid sample is drawn through this
sterile membrane filter to concentrate any contaminating micro-organisms on the
filter surface. 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.
