A selection of filtering systems are readily offered, including numerous systems in the kind of manifolds, to ensure that even more than one sample can be filteringed system at the same time.


Vendors include Millipore, Sartorius and Membrane Solutions. The filter system is attached to a suitable vacuum source to attract the samples with the filter. This may be a vacuum cleaner line or a stand-alone pump unit. Portable click for more info pump units particularly designed for use with MF approaches are now offered. An instance is the Millipore EZ-Stream unit, which can run the filteringed system sample directly to drain pipes, thus conserving time invested clearing and cleaning the waste sample containers utilized with traditional lab air pump.
