Overview
The 2L jacketed glass reactor passes through the interlayer of the double-layer reaction kettle, injects constant temperature (high or low temperature) heating or cooling liquid, and performs constant temperature heating or cooling on the reaction kettle. In the closed reaction kettle, stirring and reaction are carried out under normal pressure or negative pressure, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the material can be discharged from the outlet at the bottom of the kettle, and the operation is very convenient. It is an ideal equipment for modern chemical sample experiments, biopharmaceuticals and new material synthesis.
Working principle of 2L jacketed glass reactor:
The 2L jacketed glass reactor mainly uses its double-layer glass characteristics, we can place the reaction materials (some are called reaction solvents) in the middle interlayer, and pass them under normal pressure or negative pressure. The reaction was carried out with stirring.
The use of 2L jacketed glass reactor can be summarized into the following aspects: high temperature reaction (maximum G temperature can reach 200°C), low temperature reaction (low temperature can reach -80°C), vacuuming for negative pressure reaction, constant temperature reaction Solvent synthesis reaction, distillation reflux reaction, vacuum distillation reaction, separation and extraction reaction, purification reaction, concentration reaction, stirring reaction, etc. According to different use conditions and requirements, users can adjust the use temperature and pressure to adapt to different experimental environments.
2L jacketed glass reactor is suitable for the following experiments:
1. Processes requiring high temperature and low temperature conditions;
2. The process of depressurization and stirring at the same time;
3. Dispersion process;
4. Distillation and reflux, concentration;
Jacketed Reaction Vessel, the liner is for reaction solvent, and the jacket for heating or cooling resource(cool liquid,hot water or hot oil), to achieve circulating heating or cooling experiment. And its ancillary equipment-High and low temperature machine which can satisfy functional high & low temp reaction experiments.
Features of 2L jacketed glass reactor:
1. Frequency conversion speed regulation, geared motor, constant speed, no brush, no spark, safe and reliable, and can work continuously.
2. All glass is made of GG173.3 high borosilicate glass, which has excellent chemical and physical properties.
3. The overall stainless steel column type mobile frame structure, six-port reaction kettle cover. Large mouth design, easy to clean, the standard mouth can be equipped with distillation and synthesis devices such as reflux, liquid addition, and temperature measurement.
4. The 2L jacketed glass reactor has a stainless steel-coated PTFE stirring paddle, which is suitable for mixing liquids with low viscosity.
5. The flange of the lower discharge port and the PTFE valve, inside the container, the lower discharge material can be disassembled, which is convenient for the safe and fast discharge of solid materials.
6. Alloy steel mechanical seal, PTFE connection port, maintain high-precision sealing during work.
7. The Pt100 sensor probe has high temperature measurement accuracy and small error.
Optional Equipment:
Circulating water vacuum pump:To provide a vacuum source.

What should be paid attention to when using the 2L jacketed glass reactor？
1. Before using the 2L jacketed glass reactor, check the instrument carefully, whether the glass bottle is damaged, whether the interfaces are consistent, and handle with care.
2. Wipe each interface with a soft cloth (you can replace it with a napkin), and then apply a little vacuum grease. Vacuum grease must be covered after use to prevent lime sand from entering.
3. The joints of the 2L jacketed glass reactor should not be screwed too tightly, and should be loosened regularly to avoid long-term tight locks that cause the connectors to bite dead.
4. Turn on the power switch first, and then let the machine run from slow to fast. When stopping, make the machine stop, and then turn off the switch.
5. The PTFE switches everywhere should not be tightened too hard, as it is easy to damage the glass.
6. After each use, you must use a soft cloth to wipe off all kinds of oil stains, stains, and solvent residues left on the surface of the machine, and keep it clean.
7. Unscrew each PTFE switch after stopping the machine, and the PTFE piston will be deformed if it is still in the working state for a long time.
8. Clean the sealing ring regularly. The method is: take off the sealing ring, check whether there is dirt on the shaft, wipe it clean with a soft cloth, then apply a little vacuum grease, and reinstall it to keep the shaft and the sealing ring smooth.
9. The electrical part must not enter the water, and it is strictly forbidden to be damp.
10. It is necessary to purchase authentic accessories from the original factory. Random use of other accessories will cause fatal damage to the machine.
11. When doing any repair or inspection on the 2L jacketed glass reactor, be sure to cut off the power supply and water source first.
