In terms of tools, MF techniques require suitable filtering apparatus containing a base sustaining a permeable disc, on which the filter is placed, and a sterile filter channel, which can be secured to the base, clamping the filter in placement - Bacteria Testing. A selection of filtering systems are commercially available, including multiple systems in the form of manifolds, to make sure that greater than one example can be filtered at the same time

The filter device is attached to an appropriate vacuum cleaner resource to attract the examples via the filter. An instance is the Millipore EZ-Stream unit, which can run the filtered example straight to drain pipes, hence saving time invested emptying and cleaning up the waste example containers used with typical laboratory vacuum cleaner pumps.
