Vacuum controller for Buchi^® evaporators and vacuum pumps 

Ideally suitable for the V-700/710 vacuum pumps, but is compatible with all older models. When used with the pump or the Rotavapor, a separate power cord is not required. However, if the vacuum controller is to be used as a stand-alone device it will require a power cord.

V-850 features:
• Regulation to a specified setpoint
• Library with 43 pre-determined solvents
• Timer function
• Control of jack and rotation on the Rotavapor

V-855 features:
• EasyVac function when used with V-700/710 vacuum pump provides automatic process control based on vapor pressure detection
• Automatic distillation with the unique stage probe
• Programming for pressure gradients in specialized distillation
