Vendors include Millipore, Sartorius and Membrane Solutions. The filter device is attached to an appropriate vacuum resource to draw the samples with the filter. This may be a vacuum line or a stand-alone pump unit. Small pump devices especially designed for use with MF techniques are now available. An instance is the Millipore EZ-Stream device, which can run the filteringed system example right to drain, therefore saving time spent emptying and cleansing the waste sample containers made use check of with traditional laboratory vacuum pumps.
