A range of filtering systems are readily offered, including several units in the form of manifolds, to ensure that more than one example can be filteringed system simultaneously.

Distributors consist of Millipore, Sartorius and Membrane Solutions. The filter device is linked to an appropriate vacuum cleaner source to attract the examples with the filter. This may be a vacuum line or a stand-alone pump system. Compact pump devices especially created for use with MF methods are currently readily available. An instance is the Millipore EZ-Stream unit, which can run the filtered example directly to drain, hence saving Homepage time spent clearing and cleansing the waste sample containers used with typical lab vacuum pumps.
