Vacuum Pumps for Filtration and Solid Phase Extraction

In March 2010 Vacuubrand launched the diaphragm pumps ME 1 and ME 1C. They complete the range of compact vacuum pumps for applications like filtration and sample preparation in chemistry, microbiology, wastewater control and other analytical processes. The ultimate vacuum of 100 mbar obtains 90% of atmospheric pressure that is doing the work of forcing the media through the filter. For aqueous filtration, the ME 1 is the optimal choice; however, for more aggressive solvents, the ME 1C with its chemical resistance properties is the right solution.

The new top mounted power switch and the space saving design offers an easy-to-use functionality even with gloves and requires minimal bench top space. An optional manual control valve with dial gauge enables variable fine adjustment of the pumping speed (max. 0.7 m³/h). Both pumps allow an almost maintenance-free use. New designed from the established technology of the three-stage model line MD 1 and MD 1C they stand out due to a proven long diaphragm life.
