Vacuum degree controller is a high-precision vacuum controller developed by our company. The instrument uses an imported anti-corrosion pressure sensor and a high-sensitivity solenoid valve for high-precision control of the vacuum. It can be equipped with a rotary evaporator, rectification, reaction kettle, etc. of various manufacturers for the concentration of vacuum and equipment for vacuum control. When the vacuum is not suitable, the reagent will suddenly boil and bump. By using this fully automatic vacuum controller, it can be connected in series with the rotary evaporator to obtain the ideal vacuum inside the rotary evaporator. Especially for the concentration of volatile reagents, the most optimal recovery rate can be obtained.
