A range of purification systems are commercially available, including numerous units in the form of manifolds, to ensure that more than one sample can be filtered at the same time

The filter device is linked to an ideal vacuum resource to draw the samples with the filter. An example is the Millipore EZ-Stream unit, which can run the filtered example right to drain, thus conserving time spent emptying and cleaning the waste sample containers made use of with traditional lab vacuum cleaner pumps.
