In the laboratory, the high-pressure reactor is a commonly used experimental equipment, mainly used for chemical reactions under high temperature and high pressure. However, in the process of using the high-pressure reactor, we must strictly abide by the precautions to ensure the safety of the laboratory and the smooth progress of the experiment.

1. equipment inspection
Before using the high-pressure reaction kettle, be sure to conduct a comprehensive inspection of the equipment to ensure that the equipment is intact. The inspection contents include but not limited to: whether the seal is in good condition; whether the valve, pressure gauge and thermometer are flexible and reliable; whether there is accumulation of sundries around the equipment, etc.

2. Operation Specification
1. When operating the high-pressure reactor, it is strictly forbidden to change any parameters, such as temperature, pressure, etc.;
2. During the experiment, overpressure operation is strictly prohibited to avoid equipment damage or safety accidents.
3. Before the experiment, be sure to read the equipment operation manual carefully and abide by the operation procedures.
4. Be patient and careful during the operation, and it is strictly prohibited to act rashly.

3. safety protection
1. During operation, you must wear protective glasses, gloves and other safety protective equipment that meet the safety standards;
2. Emergency emergency equipment such as emergency eye washer and safety shower is required in the laboratory;
3. During the experiment, keep the equipment clean and tidy to prevent the accumulation of sundries.

4. emergency handling
1. If there is any abnormal situation in the experiment, such as pressure overrun, leakage, etc., do not panic, close the main valve immediately and carry out corresponding emergency treatment;
2. In case of emergency, alarm and start the emergency plan quickly to ensure the safety of laboratory personnel;

5. equipment maintenance
1. Maintain the autoclave regularly and follow the equipment maintenance cycle, regularly replace seals, lubricants and other wearing parts;
When the equipment is not used for a long time, it should be stored and packaged correctly to prevent the equipment from moisture and oxidation.

high-pressure reactor is a very important, but also more dangerous experimental equipment, we must strictly abide by the operating procedures and safety precautions, to ensure the safety of laboratory personnel, to ensure the smooth progress of the experiment. I hope everyone can take the use of high-pressure reactor seriously, safety first, prevention first, to ensure the safety of laboratory work.
