A range of filtration systems are commercially available, consisting of several systems in the form of manifolds, so that greater than one sample can be filtered at the same time.


Vendors include Millipore, Sartorius and Membrane Layer Solutions. The filter system is connected to a suitable vacuum cleaner source to attract the samples via the filter. This might be a vacuum line or a stand-alone pump system. Compact pump devices especially developed for use with MF techniques are now readily available. An example is the Millipore EZ-Stream device, which can run the filtered example directly to drain pipes, therefore conserving time spent clearing and cleaning up the waste sample containers made use of with conventional laboratory air pump.
