A range of filtration systems are readily available, consisting of multiple devices in the form of manifolds, to make sure that more than one example can be filtered at the same time.


Vendors include Millipore, Sartorius and Membrane Layer Solutions. The filter unit is linked to a suitable vacuum resource to draw the examples through the filter. This may be a vacuum line or a stand-alone pump system. Compact pump systems especially developed for usage with MF methods are currently readily available. An instance is the Millipore EZ-Stream device, which can run the filtered example straight to drain, thus saving time invested clearing and cleansing the waste sample containers made use of with traditional lab air pump.
