The safety precautions for Room Temperature Vacuum Crystallizer are the key to ensuring the normal operation of the equipment and the safety of personnel. The following is a detailed explanation of the safety precautions for Room Temperature Vacuum Crystallizer:
I. Equipment preparation and inspection
Check the equipment status: Before operation, carefully check whether the vacuum pump, vacuum gauge, hot water bath and other equipment are in normal working condition to ensure that there is no sign of damage or leakage in the equipment.
Storage and cleaning of accessories: Vacuum equipment accessories should be stored in a drying oven and away from corrosive chemical gases or liquids. At the same time, the equipment should be cleaned regularly to avoid contaminating the sample and affecting the normal progress of the next experiment.
II. Precautions during operation
Avoid direct contact: Experimental operators need to wear special operating gloves for vacuum equipment to operate, and cannot directly touch the vacuum equipment to prevent electric shock or equipment damage.
Pay attention to vacuum degree and temperature: During operation, pay close attention to changes in vacuum degree to ensure that it is within a safe range. At the same time, during the heating process, observe temperature changes in time to prevent dangers such as overflow due to excessive temperature.
Slowly add reagents: When adding chemical reagents, they should be added slowly in a dripping manner, and pay attention to adjusting the temperature and vacuum degree to ensure that the crystallization is of good quality.
III. Laboratory environment and safety
Keep dry and ventilated: The laboratory should maintain a certain degree of dryness to avoid damage to the equipment in a humid environment. At the same time, the laboratory should maintain good ventilation to avoid the impact of mechanical pump oil and gas.
Pay attention to the power supply and interface: The operator should pay attention to the loss of the high-voltage ion pump power interface to prevent electric shock accidents. After the ion pump speed drops below the safety line, nitrogen or liquid nitrogen should be put in for cooling.
Follow the operating procedures: When operating, the experimental personnel should strictly follow the operating steps of each vacuum equipment to open and close the valve to prevent the backflow caused by the pressure difference.
IV. Emergency handling
Immediate shutdown and notification: When the equipment is abnormal or fails, it should be shut down immediately and the laboratory manager and maintenance personnel should be notified for inspection and repair.
Evacuation and power off: In case of special circumstances, such as fire or explosion, all on-site personnel should be notified to leave immediately and the power supply of the vacuum equipment should be cut off to ensure the safety of personnel.
In short, the safety precautions for the operation of the Room Temperature Vacuum Crystallizer involve equipment preparation, operation process, laboratory environment and safety, and emergency handling. By strictly following these precautions, the normal operation of the equipment and the safety of personnel can be ensured.
