A variety of filtration systems are readily offered, including multiple devices in the type of manifolds, so that even more than one sample can be filteringed system simultaneously.


Vendors include Millipore, Sartorius and Membrane Layer Solutions. The filter system is connected to an ideal vacuum source to attract the examples with the filter. This may be a vacuum line or a stand-alone pump system. Compact pump devices particularly made for use with MF methods are currently available. An example is the Millipore EZ-Stream system, which can run the filtered example straight to drain, hence saving time invested emptying and cleansing the waste sample containers this article made use of with conventional research laboratory air pump.
