Other water testings
142 mm diameter polyamide membranes
of 0.2 µm or 0.45 µm pore size are specified
in a method for the collection of legionella
organisms (see page 22).
A method using a Sartocon Crossflow system
with 100,000 cut-off polyethersulfone
cassettes for the recovery of bacteriophages
in water has shown very good results.
Airborne bacteria and viruses
Gelatine membrane filters are routinely used
to quantitatively collect airborne microorganisms
for clean room and isolator monitoring.
Their effectiveness for the collection of viruses
has also been demonstrated. The gelatine
appears to have a protective effect on the
captured viruses and can be dissolved in buffer
or medium for subsequent virus detection.
A recent publication describes their use for
the routine monitoring of bacteriophages in
the ambient air of milk processing facilities.
For quicker and simpler sample filtration
Sterile, single-use funnels and monitors
replace stainless steel funnels of vacuum
holders.
Biosart 250 funnels
250 ml funnels which eliminate the need
for time-consuming sterilization between
samples. Their large inner base diameter
ensures the shortest filtration times.
Biosart 100 monitors
100 ml capacity units with filters available
in different pore sizes, filter colours and
diameters. The completely sterile units must
be used in connection with various culture
media. Lid and base form a Petri dish after
the culture medium has been added.
