A variety of filtration systems are readily readily available, including numerous devices in the type of manifolds, to ensure that more than one example can be filtered at the same time.


Distributors include Millipore, Sartorius and Membrane Solutions. The filter device is attached to an appropriate vacuum cleaner source to draw the examples through the filter. This may be a vacuum cleaner line or a stand-alone pump system. Small pump devices especially designed for use with MF techniques are currently offered. An instance is the Millipore EZ-Stream system, which can run the you can look here filteringed system example right to drain, thus saving time spent emptying and cleansing the pop over here waste sample containers made use of with standard lab air pump.
