Providers consist of Millipore, Sartorius and Membrane Layer Solutions. The filter system is linked to an ideal vacuum source to draw the samples with the filter. This may be a vacuum cleaner line or a stand-alone pump system. Small pump systems specifically created for usage with MF techniques are currently available. An example is the Millipore EZ-Stream device, which can run the filtered sample right to drain, thus conserving time spent clearing and cleaning the waste example containers utilized with conventional laboratory vacuum cleaner pumps.
