A variety of filtration systems are readily offered, consisting of several systems in the type of manifolds, to ensure that greater than one sample can be filtered simultaneously


Suppliers consist of Millipore, Sartorius and Membrane Solutions. The filter system is attached to an appropriate vacuum resource to attract the examples via the filter. This may be a vacuum cleaner line or a stand-alone pump system. Compact pump units especially created for use with MF approaches are currently available. An example is the Millipore EZ-Stream device, which can run the filtered example right to drain pipes, therefore conserving time spent emptying and cleaning the waste sample useful source containers made use of with typical research laboratory air pump.
