V-850 vacuum controller:
The V-850 vacuum controller with ¼" LCD VGA screen can be used universally for the display, control and adjustment of vacuum. The vacuum controller is a compact unit suitable for many tasks in the laboratory thanks to its integrated vent valve and chemical-resistant pressure sensor. It includes a timer, laboratory vacuum controller (Labvac) and solvent database featuring the 43 most commonly used solvents. The rotation speed control with the V-700 or V-710 vacuum pump enables accurate, hysteresis-free vacuum control with quiet operation.
Users also have the option of reducing their water consumption by adding a cooling water valve.

V-855 vacuum controller:
The V-855 vacuum controller comes with the same features as the V-850, and in addition: gradient and repetition functions for distillation in difficult conditions and the EasyVac function — automatic distillation based on vapour pressure detection.
