Selection of temperature control medium for double-layer glass reactor:

According to the required reaction temperature, temperature control media with different properties are selected as the heat transmission medium for the reaction. Low temperature, choose ice ethanol bath; normal temperature, choose water bath; high temperature, choose oil bath. When using low temperature or high temperature, pay attention to choose the appropriate medium, the key is viscosity. If the viscosity of the medium is too large, the circulating pump may not be able to carry it, the medium circulation effect is not good, and the required temperature control effect cannot be achieved. If the high-power circulating pump is rashly replaced, the pressure of the press-in medium is too large, which will easily damage the lining of the buy a glass reactor, and the chemglass jacketed reactor will rupture. Usually, manufacturers will also choose the corresponding heating medium according to their own buy a glass reactor.

 

Insulation medium of double-layer glass reactor:

Due to the small thickness of the interlayer in the middle of the chemglass 20l jacketed reactor, the thermal insulation performance is poor. In the process of using high temperature and low temperature, it is necessary to use thermal insulation materials for thermal insulation protection of the kettle body. The kettle body and the liquid-conducting pipes of the reaction kettle need to be wrapped with thermal insulation materials, and attention should be paid to the thickness of the thermal insulation layer to ensure a good thermal insulation effect.
 
The working principle of double-layer glass reactor:
The double-layer glass reaction kettle controls the temperature of the experimental materials in the inner layer of the kettle by injecting circulating liquid of high temperature or low temperature through its interlayer, and has the function of stirring, which can make the material react more quickly and uniformly. Due to the glass characteristics of the chemglass jacketed reactor and the metal bracket it uses, many details need to be paid attention to during use. It is difficult to understand the problems existing in the double-layer glass reactor without using it. This article makes some brief introductions.
 

Double glass reactor storage location:

The reaction amplification test adopts a double-layer glass reaction kettle, and its volume is generally 50~150L. The specific capacity can be adjusted according to user requirements. Therefore, the scale of the test should not be underestimated. Because the kettle body is made of glass material, stainless steel is used as the bracket, and the feet are made of casters, so the storage location should be selected carefully.
Although the casters can be fixed with foot buckles, the stability is not strong. Therefore, it is necessary to pay attention to the choice of flat laying during storage. When laying flat, keep the midpoint of the reaction kettle and the mechanical stirring consistent, otherwise it will be easy to shake and become unstable and accidents will occur. The height of the chemglass jacketed reactor is about 1.5m, and it is equipped with a vertical upward condenser. The height of the whole chemglass jacketed reactor is about 2m. Ordinary floor ventilation kitchen utensils cannot be placed, but they must be placed in a well-ventilated place.
 

Double glass reactor safety settings:

The double-glass reaction kettle has a large amount of reaction during use, and the concentration of the solvent in the surrounding air is high, so safety settings must be made. The explosion-proof design for the double-layer glass reactor is mainly to set the explosion-proof motor, explosion-proof switch and explosion-proof power controller on the stirring motor. Ordinary manufacturers can provide installation, the price is slightly more expensive, but still worth it. Due to the large amount of reaction solvent and the high concentration of surrounding air, it is very necessary to install a gas alarm in the workplace. Be sure not to stack solvent or debris around the chemglass jacketed reactor, and leave unobstructed safety passages.

 

Precautions for charging of double-layer glass reactor:

The double-layer glass reaction kettle is an independent reaction rack, which is different from the industrial reaction kettle in that the preset feeding port is small, and the feeding process is more difficult. The double-glass reaction kettle should not be charged too much at one time. It should be evaluated according to the reaction temperature, reflux and pressure, and appropriate materials should be added. Generally speaking, the feeding amount should not exceed 2/3 of the kettle body.
 
Recommendation: solid reagents can be added to the kettle together with the solution; liquid reagents can be pumped into the kettle through the matching pump or oil pump. In particular, the reaction material is added to the reaction kettle through a constant pressure dropping funnel or an ordinary dropping funnel, and a moving ladder is required for the staff to add samples.We are jacketed glass reactor manufacturer.Contact us on line.
