Advantages of vacuum controller:

KD-VC-4000 vacuum controller is a high-precision vacuum controller developed by our company. The instrument adopts imported anti-corrosion pressure sensor and high-sensitivity solenoid valve to control the vacuum with high precision. It can be equipped with vacuum concentration equipment and vacuum control equipment such as rotary evaporator, rectification and reaction kettle of various manufacturers. When the vacuum is not suitable, the reagent will suddenly boil and collide. The automatic vacuum controller can be connected in series with the rotary evaporator to obtain the ideal vacuum degree in the rotary evaporator. Especially for the concentration of volatile reagents, the best recovery rate can be obtained.

Features of vacuum controller:

1. The display part adopts 4.3-inch color TFT liquid crystal display, the system data of the operating status (settings, measured values) is clear at a glance, and the program running status, pressure status and other data can be displayed on their respective screens.

2. It can control the opening and closing of the vacuum pump, and can carry out 5-stage gradient program control.

3. Gradually control the degree of vacuum during experimental chromatography under reduced pressure distillation. With a knob to adjust the vacuum degree.

4. The piping material is acid and alkali resistant and has good chemical properties.

5. Pressure measurement range: 0～760mmHg/0～1013mbar.

6. Pressure sensor: corrosion-resistant semiconductor pressure probe.

FAQ:

What is the working principle of the vacuum controller?

The working principle of the vacuum controller is to use the rotary evaporator to concentrate, crystallize, separate, and recover the solvent under the condition of negative pressure in the conventional way. The establishment of negative pressure is completed by a vacuum pump. During the evaporation process, the negative pressure of the system will gradually decrease due to the effect of saturated steam and the trace leakage of the connecting pipe.

What equipment is the vacuum controller generally used for?

Rotary evaporator, vacuum pump, glass reactor, stainless steel reactor, etc.

What is the pressure test range of the vacuum controller?

0~760mmHg, 0~1000hPa(mbar).
