MF methods fast and easy to perform, require little incubator room and can take care of very large quantities of water if called for.

In regards to tools, MF techniques require ideal filtration apparatus consisting of a base sustaining a permeable disc, on which the filter is positioned, and a clean and sterile filter channel, which can be secured to the base, clamping the filter in placement. A selection of filtering systems are commercially readily available, consisting of multiple devices in the form of manifolds, so that greater than one sample can be filtered at when.

Distributors consist of Millipore, Sartorius and Membrane Layer Solutions. The filter system is connected to an ideal vacuum cleaner resource to attract the samples via the filter. This might be a vacuum cleaner line or a stand-alone pump unit. Portable pump devices particularly developed for use with MF techniques are now available. An instance is the Millipore EZ-Stream unit, which can run the filteringed system example straight to drain pipes, hence conserving time spent clearing and cleaning the waste example containers used with traditional laboratory vacuum cleaner pumps.
