SPD-20L short path distillation

SPD-20L short path distillation

The vacuum pressure of SPD-20L short-path distillation is 0.098Mpa, and it is equipped with cold wells, condensers and vacuum pumps to make the equipment safer and more efficient.


The short-path distillation series equipment uses high borosilicate glass, which is corrosion-resistant and durable. The glass parts are connected with frosted ports, which has good sealing performance. Uniquely designed independent cold well and collection bottle. This equipment has a simple structure, a small footprint and high evaporation efficiency.


1. Intelligent temperature control, heating accuracy is ±1°C.

2. Electric heating jacket heating, heating speed is fast.

3. The liquid surface evaporates freely without bulging.

4. High-precision transmission and mechanical seal design ensure long-term stable operation of the equipment.

5. The surface of the cylinder is smooth and not easy to stick.

1. What should I do if the flow rate of the injector is out of control in short-path distillation?

Tighten the control valve clockwise at this time. If there is no obvious improvement, remember not to use excessive force on the knob, just turn off the vacuum pump, do not perform other operations, and contact full-time personnel for processing in time.


2. What should I do if the sound of the film wiper for short-path distillation is abnormal or the rotation speed is uneven and continuous?

Turn off the heating, rotating and vacuum pumps first, and contact the person in charge of the instrument or a professional person for processing.


3. What should I do if the separation effect of short-range molecular distillation is not good?

Choose the appropriate evaporation temperature, the thinner the evaporation film, the more uniform, and the larger the coverage area, the better the distillation effect.

High material flow rate and impurities in the material will affect the separation effect.


4. What are the applications of short-path distillation?

Short-path distillation devices are widely used in pharmaceutical, laboratory fractionation and purification, food and beverage, essential oil and other industries.
