In terms of devices, MF techniques require appropriate filtration apparatus consisting of a base supporting a porous disc, on which the filter is put, and a clean and sterile filter funnel, which can be protected to the base, clamping the filter in position - Bacteria Testing. A variety of filtering systems are commercially offered, consisting of several systems in the kind of manifolds, to ensure that more than one sample can be filteringed system simultaneously

Distributors consist of Millipore, Sartorius and Membrane Solutions. The filter device is linked to an ideal vacuum cleaner resource to draw the examples via the filter. This may be a vacuum line or a stand-alone pump system. Small pump units especially designed for use with MF techniques are now readily available. An example is the Millipore EZ-Stream device, which can run the filtered sample right to drain pipes, therefore saving time invested clearing and cleaning up the waste example containers made use of with typical laboratory vacuum pumps.
