This may be a vacuum cleaner line or a stand-alone pump device. Small pump units specifically made for usage with MF techniques are now readily available. An instance is the Millipore EZ-Stream unit, which can run the filteringed system example straight to drain, hence saving time spent clearing and cleansing the waste sample containers used with traditional research laboratory vacuum pumps.
