PC 611 select, US

This chemistry vacuum pumping unit is an economic space-saving solution for simultaneous operation of two independent vacuum applications with one single pump. Based on our popular MD 4C NT three-stage chemistry diaphragm pump, the PC 611 select is frequently used for vacuum applications involving even high boiling point solvents. This pump has sufficient capacity for parallel operation of two demanding applications. One application is controlled by the VACUUSELECT vacuum controller an electronic solenoid valve. The second application is controlled by a manually controlled diaphragm valve. Both vacuum ports have integrated check valves to protect against cross contamination and interference. The integrated VACUU·SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, it detects the boiling pressure and switches to 2 point control mode to hold the pressure stable when a boiling point is detected. The inlet separator, made of
