Providers include Millipore, Sartorius and Membrane Layer Solutions. The filter device is attached to a suitable vacuum resource to draw the examples via the filter. This might be a vacuum cleaner line or a stand-alone pump system. Portable pump devices especially developed for use with MF approaches are now offered. An example is the Millipore EZ-Stream device, which can run the filtered sample directly to drain pipes, thus conserving time invested emptying and cleansing the waste sample containers utilized with conventional laboratory vacuum cleaner pumps.
