A variety of filtering systems are readily readily available, including several devices in the kind of manifolds, to ensure that greater than one example can be filteringed system simultaneously


Distributors include Millipore, Sartorius and Membrane Layer Solutions. The filter device is linked to an ideal vacuum cleaner resource to attract the samples through the filter. This may be a vacuum line or a stand-alone pump unit. Small pump systems particularly made for usage with MF methods are currently offered. An example is the Millipore EZ-Stream system, which can run the filtered example right to drain, therefore conserving time invested emptying and cleaning up the waste sample containers made use of with conventional lab vacuum pumps.
