Diaphragm vacuum pumps represent one of several pump designs ideal for creating vacuum conditions in the laboratory. As they avoid the need for pump oil, diaphragm pumps offer much higher corrosion resistance and typically require much less service support than oil-sealed pumps. Operators working in lab environments often choose a diaphragm vacuum pump for applications in which chemical resistance is important. The ultimate vacuum of a diaphragm pump can reach as low as 0.3 Torr, which is sufficient to handle most suction and evaporative applications in the lab. Chemically resistant PTFE pump heads ensure long operating life, allowing these diaphragm pumps to serve corrosion-prone rotary evaporators, or flask and bottle evacuations, all without contaminated aspirator water.

Select from a set of predefined applications, modify The PC 3004 VARIO® select combines the intuitive VACUU·SELECT® touch screen controller with variable motor speed. The VACUU·SELECT controller simpifies your work and allows VARIO select chemistry diaphragm pumps to deliver unparalleled precision. Select from a set of predefined applications, modify an existing process or create your own using the drag-and-drop editor. With automatic evaporation, the pump's motor speed continuously adapts to system demands optimizing process times. The PC 3004 VARIO select delivers exceptional performance in a compact, durable and low-maintenance design. Chemically-resistant wetted materials allow the pump to be used with aggressive gases and vapors. The oil-free design contributes to clean processes and products as well as eliminating the time and expense related to oil-changes. The inlet separator prevents particles and liquid droplets from entering the pump, extending pump life. The exhaust vapor condenser allows for nearly 100% solvent recovery. With high pumping speeds and an ultimate vacuum of 1.5 mbar, the PC 3004 VARIO select supports a variety of larger scale lab applications....
