A variety of purification systems are commercially readily available, consisting of multiple devices in the type of manifolds, to ensure that more than one example can be filteringed system at the same time.

Providers consist of Millipore, Sartorius and Membrane Solutions. The filter system is connected to an appropriate vacuum cleaner source to draw the examples through the filter. This may be a vacuum cleaner line or a stand-alone pump unit. Small pump devices specifically developed for usage with MF methods are now offered. An instance is the Millipore EZ-Stream unit, which can run the filtered example straight to drain, therefore conserving time invested clearing and cleaning Home Page the waste sample containers utilized with traditional lab vacuum cleaner pumps.
