A selection of filtering systems are readily offered, including multiple units in the kind of manifolds, so that even more than one sample can be filtered at the same time.


Distributors include Millipore, Sartorius and Membrane Layer Solutions. The filter system is attached to a suitable vacuum cleaner resource to draw the examples through the filter. This may be a vacuum cleaner line or a stand-alone pump unit. Portable pump units particularly made for use with MF approaches are now offered. An instance is the Millipore EZ-Stream unit, which can run the filtered example right to drain, therefore conserving time spent emptying and cleaning up the waste example containers used with standard research laboratory air pump.
