This may be a vacuum cleaner line or a stand-alone pump unit. Small pump units specifically designed for use with MF techniques are currently have a peek here readily available. An instance these details is the Millipore EZ-Stream unit, which can run the filteringed system example right to drain, therefore saving time spent emptying and cleaning up the waste example containers made use of with typical laboratory vacuum pumps.
