Vacuum Controller V-850/855 - the smart way to regulate a vacuum

The vacuum controllers are the result of close collaboration with customers during development to adapt the controllers even more precisely to the needs of day-to-day work in the laboratory. Only a defined, regulated vacuum will provide controlled conditions for a quick, reliable evaporation process. The integrated aeration valve and the precision pressure sensor is resistant to chemicals - a key feature for a compact Vacuum Controller suitable for numerous applications in the lab.

Reliable and simple to use


Vacuum Controller V-850, designed for standard applications with following functions:

  • Vacuum regulation of set pressure with the  Vacuum Pump V-700 / V-710 by speed regulation or by switching on and off the vacuum valve. The novel speed control allows a hysteresis-free vacuum control with quiet operation
  • Timer function for stopping the process after a preset time
  • LabVac function: intelligent control of the pump in a laboratory system with several consumers
  • Buchi wizard for a quick configuration using simple menu control
  • USB interface for data transfer to PC for storage, evaluation and optimization
  • The solvent library is an integrated library with 43 present solvents that can be expanded by the customer. This function considerably simplify the parameter selection

Vacuum Controller V-855, the top model offers additional features as:

  • Programming function for pressure gradients for special distillation tasks, ideal for difficult to distil products like foaming extracts or those with boiling delay
  • EasyVac function:automatic process control based on vapour pressure detection - it couldn`t be easier. The EasyVac function guarantees the simplified, automatic distillation of individual solvents and complex solvent mixtures, whenever time is the issue during distillation
  • Automatic distillation with a stage probe positioned in the rotary evaporator`s condenser. The stage probe is suitable for foaming substances or for maximum solvent recovery
  • Repeat function: The pressure curve of a manual or automatic distillation can be stored and retrieved anytime as set point values for optimum process conditions
