A variety of filtration systems are commercially available, including several systems in the type of manifolds, to make sure that greater than one sample can be filtered at once.


The filter unit is attached to an ideal vacuum source to attract the examples with the filter. An instance is the Millipore EZ-Stream device, which can run the filtered example right to drain, thus conserving time spent clearing and cleaning up the waste sample containers utilized with conventional lab vacuum pumps.
