A variety of purification systems are commercially available, consisting of several devices in the form of manifolds, to make sure that more than one sample can be filteringed system simultaneously.

Suppliers include Millipore, Sartorius and Membrane Layer Solutions. The filter system is connected to a suitable vacuum source to attract the samples with the filter. This might be a vacuum cleaner line or a stand-alone pump system. Portable pump systems particularly developed for use with MF techniques are now offered. An example is the Millipore EZ-Stream unit, which can run the filteringed system sample right to drain pipes, therefore saving time invested clearing and cleaning the waste example containers utilized with conventional lab air pump.
