Overview
The 20L jacketed glass reactor adopts frequency conversion speed regulation, AC induction motor, constant speed, no brush, no spark, safe and stable, and can work continuously. The whole set of glass instruments is made of high borosilicate glass, which has good chemical and physical properties. The glass interlayer interface is connected to hot oil and circulated, which can be used for heating reaction. It can react at room temperature, and the reflected heat can be quickly taken away by tap water.
Working principle of 20L jacketed glass reactor:
Through the interlayer of the 20L jacketed glass reactor, a constant temperature (high or low temperature) hot solution or cooling liquid is injected to heat or cool the materials in the 20L jacketed glass reactor, and agitation can be provided. The materials are reacted in a 20L jacketed glass reactor, and the evaporation and reflux of the reaction solution can be controlled. After the reaction, the materials can be released from the outlet at the bottom of the tank, which is very convenient to operate. It is an ideal equipment for modern chemical sample, petrochemical, medium sample experiment, biopharmaceutical and new material synthesis. It is clear at a glance for the pharmaceutical reaction process, and it is convenient to control the reaction process.
How to use the 20L jacketed glass reactor:
1. Check whether the power supply voltage is consistent with the specifications provided on the machine nameplate.
2. Plug in the power plug, turn on the power switch on the inverter, and use the speed control knob to select a suitable speed.
3. The flow of materials and the power of the motor speed may resonate at a certain point, please change the speed of the motor to avoid resonance.
4. After the stirring rod is installed, it must be rotated by hand. Pay attention to whether the concentricity is good. If the concentricity is not good, loosen the heavy clamp, and then turn on the power after clamping. Adjust gradually from slow to fast.
5. Using the stirring rod regulator, the stirring blade can be moved up and down by 5cm as required.
6. If the sealing performance of the kettle is found to be reduced, please check the rotating bearing in the agitator sleeve.
Experiments that can be done with 20L jacketed glass reactor:
1. Vacuum stirring reaction;
2. High temperature, low temperature reaction;
3. Mix and react at a constant speed;
4. It can be distilled, refluxed and concentrated;
5. Negative pressure operation, liquid separation function;
6. Carry out rectification by assembling the rectification column;
7. Assemble into a glass reactor production line according to specific requirements;
8. For plant extraction, concentration has a good process effect;
9. Stirring and separation, equipped with liquid separation device, the effect is obvious;
10. Carry out the reaction production of ultrafine powder;
11. It can replace the rotary evaporator for high-purity material concentration, equipped with ultrasonic stirring, and double the reaction time;
12. Regardless of separation or synthesis, it is convenient to add materials and easy to operate.
Features
Features of 20L jacketed glass reactor:
1. It is sealed with PTFE material and special rubber composite sealing ring, which is resistant to various solvents and maintains high vacuum, which is very convenient to use.
2. Condenser to ensure high recovery rate.
3. The standardized connection method makes disassembly very convenient.
4. Equipped with a discharge switch, it is very fast to recover the solvent.
5. Equipped with a vacuum gauge, the highest working vacuum degree can be selected for materials with low boiling point.
6. Reasonable structure and exquisite materials. The whole machine is made of stainless steel, aluminum alloy and new synthetic materials, which have the advantages of anti-corrosion, anti-rust and resistance to various solvents.
7. The glass parts are all made of high temperature resistant borosilicate glass material, which has good physical and chemical properties.
8. The electrical components are carefully selected, and the main components are all imported original parts.
How to maintain the 20L jacketed glass reactor:
1. Check the instrument carefully before using the 20L jacketed glass reactor to see if the glass bottle is damaged and whether the interfaces are consistent. 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 connectors should not be screwed too tightly, but should be loosened regularly to avoid the connectors being seized by long-term locking.
4. Turn on the power switch of the 20L jacketed glass reactor 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 off 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. The 20L jacketed glass reactor must 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 20L jacketed glass reactor, be sure to cut off the power supply and water source first.
The 20L jacketed glass reactor can be combined with circulating water multi-purpose vacuum pump, diaphragm vacuum pump, circulating cooler, constant temperature circulator, low-temperature cooling liquid circulating pump, closed refrigeration and heating circulation device, etc. to form a system device.
