A variety of purification systems are commercially available, including multiple systems index in the type of manifolds, to make sure that greater than one sample can be filtered simultaneously.

The filter unit is connected to an appropriate vacuum cleaner resource to draw the examples via the filter. An instance is the Millipore EZ-Stream unit, which can run the filtered example right to drain pipes, therefore conserving time spent emptying and cleaning the waste sample containers made use of with traditional lab vacuum pumps.
