A selection of filtration systems are readily readily available, consisting of multiple devices in the form of manifolds, to make sure that greater than one example can be filteringed system simultaneously.


Suppliers consist of Millipore, check this site out Sartorius and Membrane Layer Solutions. The filter unit is attached to a suitable vacuum cleaner source to draw the examples through the filter. This might be a vacuum line or a stand-alone pump system. Portable pump systems especially developed for usage with MF approaches are now offered. An instance is the Millipore EZ-Stream unit, which can run the filtered example right to drain, thus conserving time invested clearing and cleaning the waste sample containers used with conventional lab vacuum pumps.
