The filter is after that moved aseptically to the surface area of an agar plate, or an absorptive pad saturated with an appropriate discerning medium and incubated. Nests are permitted to create on the surface area of the filter and can be counted and examined directly. MF approaches fast and easy to execute, need little incubator room and can take care of huge volumes of water if called for.

In terms of devices, MF techniques require ideal filtering device consisting of a base sustaining a permeable disc, on which the filter is positioned, and a sterile filter channel, which can be safeguarded to the base, clamping the filter in setting. A selection of filtration systems are commercially offered, including numerous devices in the form of manifolds, so that more than one example can be filtered at when.

Vendors include Millipore, Sartorius and Membrane Solutions. The filter system is attached to a suitable vacuum Web Site source to draw the samples via the filter. This may be a vacuum cleaner line or a stand-alone pump unit. Small pump units particularly designed for usage with MF methods are now offered. An instance is the Millipore EZ-Stream device, which can run the filtered example straight to drain, hence conserving time invested emptying and cleaning up the waste example containers utilized with typical research laboratory air pump.
