In regards to equipment, MF techniques require suitable purification apparatus being composed of a base sustaining a permeable disc, on which the filter is positioned, and a sterile filter channel, which can be safeguarded to the base, securing the filter in placement. A range of filtering systems are readily offered, including numerous systems in the kind of manifolds, to ensure that more than one example can be filtered simultaneously.


Providers consist of Millipore, Sartorius and Membrane Solutions. The filter system is connected content to an appropriate vacuum cleaner source to draw the samples with the filter. This may be a vacuum line or a stand-alone pump device. Portable pump systems particularly developed for use with MF approaches are currently available. An example is the Millipore EZ-Stream device, which can run the filtered sample right to drain, thus conserving time invested emptying and cleansing the waste sample containers used with typical lab vacuum pumps.
