Vacuum Controller V-850/V-855

Vacuum Controllers that cover all needs

Innovative features, intuitive operation and a variety of applications

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
