A selection of filtering systems are commercially readily available, including numerous systems in the form of manifolds, so that greater than one example can be filtered at when.


Providers consist of Millipore, Sartorius and Membrane Solutions. The filter device is linked to an ideal vacuum cleaner source to attract the samples via the filter. This may be a vacuum line or a stand-alone pump device. Compact pump systems specifically made for use with MF techniques are now readily available. An example is the Millipore EZ-Stream unit, which can run the filteringed system sample directly to drain pipes, thus saving time invested clearing and cleaning the waste example containers utilized with conventional laboratory air pump.
