The utilization of the full potential of vacuum pumps is achieved with a vacuum controller. The V-850 and V-855 vacuum controllers have been developed in close collaboration with customers, making them even better suited to the needs of everyday laboratory work. The intuitive operation caters to a wide range of applications, from simple vacuum level adjustment to the automatic distillation of complex mixtures, leaving nothing to be desired.
The advantages of the new vacuum controllers are compelling:
- Reliable and easy handling
- Speed control through individual stroke control of the V-700/710
- Compatible with both the pump and rotary evaporator
The V-850 and V-855 vacuum controllers are universally applicable for the display, control, and regulation of vacuum. The integrated vent valve and chemical-resistant precision pressure sensor make the vacuum controller a compact unit suitable for numerous laboratory applications. The innovative speed control, in combination with the V-700 or V-710 vacuum pump, enables hysteresis-free, precise vacuum operation with quiet performance.
