Vendors consist of Millipore, Sartorius and Membrane Layer Solutions. The filter device is linked to an ideal vacuum source to attract the samples via the filter. This may be a vacuum cleaner line or a stand-alone pump device. Small pump units specifically made for usage with MF methods are currently readily available. An instance is the Millipore EZ-Stream device, which can run the filteringed system example directly to drain pipes, therefore conserving time invested clearing and cleaning the waste sample containers made use of with traditional lab vacuum pumps.
