A variety of filtering systems are commercially offered, including numerous units in the kind of manifolds, to ensure that even more than one example can be filtered at as soon as.


The filter unit is connected to an ideal vacuum cleaner source to attract the samples through the filter. An example is the Millipore EZ-Stream system, which can run the filteringed system sample right to drain pipes, hence saving time spent emptying and cleaning up the waste example containers used with conventional lab vacuum cleaner pumps.
