A range of filtering systems are commercially readily available, consisting of several devices in the type of manifolds, so that greater than one example can be filtered at the same time.

Vendors include Millipore, Sartorius and Membrane Solutions. The filter system is linked to an appropriate vacuum source to attract the examples via the filter. This might be a vacuum cleaner line or official source a stand-alone pump system. Compact pump systems especially created for usage with MF methods are currently available. An instance is the Millipore EZ-Stream system, which can run the filteringed system sample right to drain pipes, therefore saving time invested clearing and cleansing the waste sample containers made use of with standard research laboratory vacuum pumps.
