The PC 3003 VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. With its high pumping speed and deep ultimate vacuum, this pump is suitable for demanding applications with high boiling point solvents in low temperature conditions. 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 fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary. And the VARIO control algorithm maintains the desired vacuum level without running the motor faster than necessary. This prevents bumping and foaming, makes the pump whisper quiet, and extends maintenance intervals. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection. Typical applications are all evaporation processes. They can be run fully automatically by the integrated vacuum controller CVC 3000 resulting in both shorter process times and extra sensitivity at the same time. The excellent ultimate vacuum allows even high boiling solvents to evaporate at low temperatures. The VARIO® control ensures high process reliability through prevention of superheating or foaming. It detects boiling pressures of solvents fully automatically and adapts continuously the vacuum conditions to changing process parameters. All this without any need of parameter input or the use of a solvent library. In many other applications - like in local vacuum networks - the VARIO® control offers a significant advantage by supplying always the appropriate pumping speed. The VACUU·BUS® interface facilitates an user-friendly configuration of even complex vacuum installations.
