A selection of filtering systems are commercially readily available, consisting of several units in the form of manifolds, to make sure that greater than one sample can be filtered at when.

Providers include Millipore, Sartorius and Membrane Layer Solutions. The filter system is connected to a suitable vacuum cleaner resource to draw the samples with the filter. This may be a vacuum line or a stand-alone pump system. Small pump devices specifically made for use with MF approaches are now offered. An example is the Millipore EZ-Stream device, which can run the filteringed system sample right to drain pipes, hence saving time invested clearing and cleansing the waste example containers utilized with conventional research laboratory vacuum pumps.
