Buchi V-855 Vacuum Controller
The Buchi V-855 Vacuum Controller is a stand alone valve unit for operation with external vacuum systems, such as the Buchi V-700 vacuum pump and Buchi V-710, which work with the R-210 rotovap system and R-215 rotovap system. 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. The controller features 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. The integrated aeration valve and the precision pressure sensor are resistant to chemicals, making the controller suitable for numerous applications in the lab. The V-855 offers gradient and repetition function for gentle distillation under strict requirements, gentle autodistillation for varying solvents and mixtures, and the EasyVac function, which provides automatic evaporation based on vapor pressure detection.
All of our equipment is fully tested to perform at factory specifications before being shipped.
