A variety of purification systems are commercially offered, including multiple devices in the type of manifolds, to ensure that greater than one example can be filteringed system simultaneously.


The filter unit is attached to a suitable vacuum source to draw the samples with the filter. An example is the Millipore EZ-Stream unit, which can run the filteringed system example straight to drain, hence conserving time invested clearing and cleaning the waste example containers made use of with typical research laboratory vacuum pumps.
