Distributors consist of Millipore, Sartorius and Membrane Layer Solutions. The filter device is linked to a suitable vacuum cleaner source to attract the samples via the filter. This might be a vacuum line or a stand-alone pump device. Compact pump devices specifically developed for usage with MF methods are currently available. An instance is the Millipore EZ-Stream system, which can run the filteringed system sample directly to drain, hence saving time invested clearing and cleaning the waste example containers utilized with typical lab air pump.
