A variety of filtering systems are readily readily available, consisting of numerous devices in the type of manifolds, so that greater than one example can be filtered at the same time.

Suppliers include Millipore, Sartorius and Membrane Solutions. The filter device is linked to a suitable vacuum cleaner source to draw the examples through the filter. This may be a vacuum cleaner line or a stand-alone pump device. Small pump systems particularly developed for usage with MF approaches are currently available. An example is the Millipore EZ-Stream system, which can run the filtered example straight to drain, hence conserving time invested clearing and cleansing the waste sample containers used with standard laboratory air pump.
