A selection of purification systems are commercially readily available, consisting of numerous devices in the kind of manifolds, so that more than one example can be filteringed system at once.


The filter unit is connected to an appropriate vacuum source to draw the examples with the filter. you could look here An instance is the Millipore EZ-Stream unit, which can run the filteringed system example Home Page directly to drain pipes, therefore conserving time spent emptying and cleaning the waste sample containers made use of with conventional laboratory vacuum pumps.
