Buchi V-850 Vacuum Controller


The Buchi V-850 Vacuum Controller is a stand alone valve unit for operation with external vacuum systems, such as the Buchi V-700 vacuum pump which works with the R-210 rotovap systems. The easy-to-operate V-850 units are equipped with a single control knob and a large graphic display screen with intuitive menu guidance and six selectable language options. Both controllers feature a solvent database, a timer function for process termination, and a LabVac function for control of laboratory vacuum systems. Units are equipped with a USB port and RS-232/RS-485 interfaces.


All of our equipment is fully tested to perform at factory specifications before being shipped.
