A range of purification systems are readily available, including numerous devices in the kind of manifolds, to ensure that greater than one example can be filteringed system simultaneously.

The filter device is connected to a suitable vacuum cleaner source to attract the examples via the filter. An example is the Millipore EZ-Stream unit, which can run the filteringed system example directly to drain, therefore conserving time spent emptying and cleaning up the waste sample containers used with conventional research laboratory vacuum cleaner pumps.
