A range of filtering systems are commercially available, consisting of multiple devices in the kind of manifolds, so that greater than one example can be filteringed system at once.

The filter unit is connected to an appropriate vacuum source to draw the examples through the filter. An example is the Millipore EZ-Stream unit, which can run the filtered example straight to drain, hence conserving time invested clearing and cleaning up the waste example containers utilized with traditional lab vacuum pumps.
