In terms of devices, MF techniques call for suitable filtering apparatus containing a base supporting a permeable disc, on which the filter is positioned, and a sterilized filter channel, which can be secured to the base, securing the filter in position. A range of purification systems are commercially available, consisting of numerous units in the type of manifolds, so that greater than one example can be filteringed system at as soon as.


Suppliers include Millipore, Sartorius and Membrane Layer Solutions. The filter unit is connected to an appropriate vacuum cleaner source to draw the samples with the filter. This may be a vacuum cleaner line or a stand-alone pump system. Portable pump systems especially made for use with MF methods are now offered. An instance is the Millipore EZ-Stream unit, which can run the filtered sample directly to drain pipes, thus conserving time spent clearing and cleaning the waste sample containers made use of with conventional research laboratory air pump.
