Vendors include Millipore, Sartorius and Membrane Layer Solutions. The filter system is linked to an ideal vacuum cleaner source to draw the sites examples via the filter. This may be a vacuum line or a stand-alone pump unit. Small pump systems particularly designed for usage with MF methods are now available.
