Microsart® mini.vac
Microsart® maxi.vac
Two electric neoprene membrane pumps, oil- and maintenance-free with a low noise level.
Microbiological analysis by the membrane filtration method allows large sample volumes with low microbial count to be tested. Growth inhibitors can be rinsed out after filtration, before incubation.
Membrane Filtration Method
A gridded membrane filter is placed on a filter support and on top a funnel is fitted on. The sample is filtered. In this process microorganisms in the test sample are retained on the filter surface by the screening action of the membrane filter.
Finally, the membrane filter is placed on a culture medium and incubated.
Nutrients and metabolites are exchanged through the pore system of the membrane filter. Colonies, which have developed on the membrane filter surface during incubation, are counted and related to the sample volume.
