In regards to tools, MF techniques require suitable filtration device containing a base supporting a permeable disc, on which the filter is put, and a sterilized filter channel, which can be protected to the base, clamping the filter in setting. A selection of purification systems are readily readily available, consisting of numerous units in the kind of manifolds, so that greater than one sample can be filteringed system at the same time.

Suppliers consist of Millipore, Sartorius and Membrane Layer Solutions. The filter unit is connected to an ideal vacuum source to attract the samples with the filter. This might be a vacuum cleaner line or a stand-alone pump device. Small pump units especially made for usage with MF techniques are currently offered. An example is the Millipore EZ-Stream system, which can run the filteringed system example straight to drain pipes, hence conserving time spent clearing and cleaning the waste example containers made use of with typical lab vacuum pumps.
