• Host:integral vacuum control system with high control precision, anti-corrosion and long service life.
• Big color LCD touch screen displaying the detected vacuum degree and set vacuum degree.Vacuum degree can be adjusted easily on the LCD screen.
• Can be connected with vacuum pumpand use with rotary evaporator,to achieve precise control of the vacuum degree of rotary evaporator. So the collection rate of low boiling point materials(such as methylene dichloro, benzene, trichloroethane and ethanol) can be increased. Inert gas can be injected to avoid inner material from pollution and oxidation.
• The process control of 5 stages gradient distillation (with time and vacuum set at certainj figures) can be carried out during the vacuum distillation of synthetic experimental chromatography,with vacuum degree controlled step by step.
• Menu operation: English and Chinese operation menu can be switched easily.
• Operation vacuum degree and operation pressure can be switched easily.
• Vacuum degree change can be checked in graphic form, which is vivid.
• USB interface can be used for data output.
• The vacuum pump with controller and solvent recovery consisits of a vacuum controller, a diaphragm pump,

A coil condenser, a S35 receiving flask500ml and a waste absorption equipment. Apart from vacuum control, it also improves the collection rate, reduced environment pollution. The self circulating purification system also prevent waste leakage from going into disphragm and cause breakage.
