A range of purification systems are commercially offered, consisting of several systems in the form of manifolds, to ensure that more than one example can be filtered at the same time.

Vendors consist of Millipore, Sartorius and Membrane Solutions. The filter device is attached to a suitable vacuum resource to draw the examples with the filter. This may be a vacuum cleaner line or a stand-alone pump unit. Portable pump systems particularly created for use with MF techniques are currently readily available. An example is the Millipore EZ-Stream device, which can run the filteringed system sample straight to drain pipes, thus conserving time invested emptying and cleaning the waste example containers made click this link use of with conventional laboratory vacuum cleaner pumps.
