Suppliers include Millipore, Sartorius and Membrane Layer Solutions. The filter over here system is attached to a suitable vacuum cleaner source to attract the samples through the filter. This may be a vacuum cleaner line or a stand-alone pump unit. Small pump devices especially made for usage with MF techniques are now available. An instance is the Millipore EZ-Stream unit, which can run the filtered sample directly to drain, hence saving time invested emptying and cleaning the waste sample containers used with conventional lab air pump.
