The filter device is attached to an ideal vacuum source to draw the examples through the filter. An instance is the Millipore EZ-Stream system, which can run the filteringed system sample straight to drain, thus conserving time invested clearing and cleaning up the waste example containers made use of with standard research laboratory vacuum pumps.
