A variety of purification systems are readily readily available, including several units in the kind of manifolds, so that greater than one sample can be filtered at as soon as

Vendors include Millipore, Sartorius and Membrane Layer Solutions. The filter system is linked to an appropriate vacuum cleaner resource to attract the samples via the filter. This may be a vacuum line or a stand-alone pump device. Small pump units particularly created for usage with MF methods are now readily available.
