A range of filtering systems are commercially readily available, including numerous systems in the kind of manifolds, so that greater than one sample can be filtered simultaneously.


Distributors include Millipore, Sartorius and Membrane Layer Solutions. The filter device is linked to an ideal vacuum like it source to attract the examples through the filter. This might be a vacuum cleaner line or a stand-alone pump unit. Small pump devices particularly designed for use with MF approaches are now available. An instance is the Millipore EZ-Stream device, which can run the filtered sample directly to drain pipes, hence saving time spent emptying and cleaning up the waste example containers made use of with conventional lab vacuum cleaner pumps.
