A range of purification systems are commercially readily available, consisting of multiple units in the form of manifolds, to ensure that greater than one example can be filteringed system simultaneously.

Suppliers include Millipore, Sartorius and Membrane Solutions. The filter unit is connected to an appropriate vacuum resource to attract the examples through the filter. This may be a vacuum line or a stand-alone pump device. Portable pump devices particularly made for usage with MF approaches are now readily available. An example is the Millipore EZ-Stream system, which can run the filteringed system example straight to drain pipes, thus conserving time spent emptying and cleaning the waste example containers used with traditional research laboratory air pump.
