In regards to tools, MF approaches require suitable purification apparatus including a base supporting a porous disc, on which the filter is positioned, and a sterile filter funnel, which can be secured to the base, clamping the filter in placement. A variety of filtration systems are readily readily available, consisting of numerous systems in the type of manifolds, so that more than one example can be filteringed system at when.

Providers include Millipore, Sartorius and Membrane Layer Solutions. The filter unit is linked to an appropriate vacuum cleaner source to draw the examples via the filter. This may be a vacuum cleaner line or a stand-alone pump system. Small pump units specifically created for usage with MF approaches are currently available. An example is the Millipore EZ-Stream system, which can run the filtered example right to drain pipes, hence conserving time spent emptying and cleansing the waste sample containers used with traditional research laboratory air pump.
