Suppliers consist of Millipore, Sartorius and Membrane Solutions. The filter device is attached to an appropriate vacuum cleaner source to attract the samples with the filter. This may be a vacuum cleaner line or a stand-alone pump device. Small pump systems particularly developed for usage with MF methods are now offered. An instance is the Millipore EZ-Stream device, which can run the filteringed system sample directly to drain pipes, hence conserving time spent emptying and cleaning the waste sample containers used with typical laboratory vacuum cleaner pumps.
