BrandTech’s improved VACUUBRAND PC3001 VARIOPRO is a completely integrated dry diaphragm vacuum system for rotary evaporation. Featuring upgraded software and free air capacity improved 20% over the previous version, this model can find and follow boiling curves without preprogramming. Vacuum levels are continually optimized for virtually bump-free evaporation up to 30% faster than traditional control, with minimal oversight. A powerful 34 L/min (1.2 cfm) free air capacity and 1.5 Torr (2 mbar) ultimate vacuum evaporates high boiling point solvents in even the largest benchtop rotary evaporators. Other control modes include hysteresis-free “single point” control, programmable ramps and control/validation via RS232. The intuitive CVC3000 vacuum controller features multilingual (choose from14 languages) operation, digital and analog vacuum display in selectable units and turn-and-push jogwheel control. An integrated inlet catchpot and outlet condenser complete this compact system. The system is ultra-low maintenance with no oil to monitor or change. Also, no cold trap is required to protect the pump. The typical service interval is well in excess of 10,000 operating hr.
