Short Path Distillation Apparatus For Sale-Precise Molecular Separation

Short path distillation apparatus is a special liquid mixture that separates the liquid mixture by using the difference in the evaporation rate of the components in the liquid material under the condition of high vacuum, so that the mean free path of the vapor molecules is greater than the distance between the evaporation surface and the condensation surface. - Liquid separation technology. It is not only used in the field of medicine, petroleum, but also widely used in the field of food.

 

1. What are the components of the Short path distillation apparatus?

Heating part (electric heating mantle), evaporating flask, distillation elbow, four-neck flask, receiving flask, cold well.

 

2. What is the function of the cold well of cdu 1000 distillation?

Filter some gases, liquid gases, impurities, and enter the vacuum pump to pollute the vacuum oil.

 

3. What is the role of Short path distillation apparatus?

The evaporative extraction of the material was carried out under vacuum.

 

4. What kinds of film scrapers are there in Short path distillation apparatus and how to choose?

Rolling film type, sliding film type, hinge wiper type, suitable film scraper can be selected according to the viscosity and processing properties of the material.

 

5. What is short path distillation kit thc?

The driving force of the steam flow is the pressure difference between the boiling film and the condensing surface, and a small pressure drop will cause the steam to flow. Operating at 1 mbar and requiring a short distance between the boiling surface and the condensing surface, a still made according to this principle is called a short path still.

 

6. What is the distillation process of 20l short path distillation kit?

Molecules diffuse from the main body of the liquid phase to the evaporation surface, the molecules evaporate freely on the surface of the liquid layer, the molecules fly from the evaporation surface to the condensation surface, and the molecules condense on the condensation surface.

 

7. What is the maximum vacuum degree that Short path distillation apparatus can achieve?

The maximum vacuum degree is 0.098Mpa.

 

8. What are the preparations before the Short path distillation apparatus starts up?

First turn on the cooling water circulation pump, adjust the temperature and pre-condensate, turn on the rotor of the film scraper, and test it to see if it rotates evenly and continuously, and secondly, listen to whether there is any noise in the sound of the scraping film.

  

9. What should I do if the flow rate of the injector is out of control in the Short path distillation kit thc?

At this time, after tightening the control valve clockwise and there is no obvious improvement, remember not to use too much force on the knob, only turn off the vacuum pump, do not perform other operations, and promptly contact the person in charge of the instrument or full-time personnel for handling.

 

10. What should I do if the sound of the wiper of the Short path distillation apparatus is abnormal or the rotation speed is not uniform and continuous?

First, turn off the heating, rotation and vacuum pumps, and contact the person in charge of the instrument or professional personnel for processing.

 

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

Select the appropriate evaporation temperature, the material flow rate is too high, affecting the separation efficiency, there are impurities in the material, the thinner and more uniform the evaporation liquid film, the larger the summer cover area, the better the distillation effect.

 

12. What are the precautions for using Short path distillation apparatus?

It is not advisable to run at high speed with no load, keep the speed regulation and the motor dry, because the life of the electrical box and the surrounding humidity and temperature have a great influence, please avoid the impact damage to the glass by hard objects such as watches and rings when operating the instrument.

 

13. What materials are mainly used in the Short path distillation apparatus?

The main raw materials produced by the short-path distillation kit are borosilicate glass, polytetrafluoroethylene, 304 stainless steel and other materials. They all have good chemical resistance and are very good laboratory distillation equipment.

 

14.What is the heating form of Short path distillation kit thc?

The short-path distillation unit uses an electric heating mantle to provide the heat source for the entire short-path distillation system. The electric heating mantle can be heated up to 250°C under the condition that the whole equipment is under negative pressure. This heating mantle has a magnetic stirring function, which helps the contents of the reaction flask to be distilled out more quickly.

 

15. What are the models of your Short path distillation kit thc?

SPD-2L, SPD-5L, SPD-10L, SPD-20L. Customization is acceptable.

 

16. What are the applications of short path distillation?

As a hot product of our company, short-path distillation is committed to high efficiency and low cost. At the same time, this short-path distillation unit is widely used in pharmaceutical, laboratory fractionation and purification, food and beverage, essential oil and other industries.

  

17. What is laboratory short path distillation?

Short path distillation is a distillation technique that involves the flow of distillate over a short distance, usually just a few centimeters, usually under reduced pressure.

18. What are the characteristics of the magnetic stirring heating mantle?

Provides a large heating area, uniform heating, and rapid heating. PAPST series brushless DC motors have stable performance, low noise, long life and no sparks.

 

19. How does Short path distillation kit thc work?

In a short path distillation unit, a liquid solution or emulsion is suspended in an evaporating flask, which is connected by a short feed to a condenser or cooling device. The evaporating flask is placed in a heating mantle which gradually increases the temperature of the solution to a predetermined boiling point, thereby promoting the evaporation of the different compartments of the solution.

 

20.What are the application scope of Short path distillation kit thc?

It can replace the conventional falling film evaporator for distillation, purification, concentration and decolorization of petrochemical and chemical products;

It is especially suitable for distillation and refining of heat-sensitive and easily oxidized chemical industrial products;

It can also be used for distillation separation of high boiling point products.
