Buchi V-850/855 Vacuum Contollers
The V-850/855 vacuum controller is an ideal supplement to the Rotavapor. Sitting on top of and directly attached to the Rotovap control panel, the clear digital displays ensure that
all process parameters are visible at a glance. An RS-485 interface provides communication and power supply for the vacuum controller, ensures automatic detection and the intuitive
operating system covers all your requirements, from simple maintenance of the set vacuum to the automatic distillation of complex mixtures.
Features common to both units include
Chemical-resistant precision pressure sensor with capacitive measuring principle
An integrated solvent library with 43 present solvents that can be expanded by the customer.
Integrated ventilation valve which opens in the event of a power failure and prevents over-pressure in the system
Ease of operation though a rotary knob and large graphic display, USB port allows data transfer
Innovative speed regulation in combination with the Vacuum Pump V-700 or V-710 provides a hysteresis free precise vacuum combined and quite operation
LabVac function to allow intelligent control of a Buchi vacuum pump as part of a vacuum system with several other users
In addition to all the above, the V-855 model also offers the following additional features:
Programming function for pressure gradients, ideal for difficult to distil products like foaming extracts or those with boiling delay
EasyVac function – an automatic process control based on vapour pressure detection which guarantees simplified, automatic distillation of individual solvents and complex solvent
Automatic distillation with a stage probe positioned in the rotary evaporator`s condenser.
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
