The principles of proper use of laboratory equipment are as follows:
1. Mechanical laboratory equipment must be operated under no-load before use to ensure no faults before loading. Lubricate before use, wipe clean after use, pay attention to daily maintenance and maintenance.
2. Laboratory equipment is not allowed to be dismantled or dismantled at will, and it is necessary to develop new functions or upgrades, etc., and it is necessary to implement the approval procedures according to the hierarchical management authority.
3. Frequently carry out maintenance and maintenance of laboratory equipment, and store it in a dry and ventilated place. If the laboratory equipment is too long, it should be powered on regularly to prevent the mold from damaging the parts of the laboratory equipment.
4. Establish regular calibration and standardization of technical indicators for large-scale precision and valuable laboratory equipment, and maintain the necessary technical indicators. Make good use of the original record.
5. When using laboratory equipment, carefully read the technical manual, familiar with the technical indicators, work performance, use methods, precautions, and strictly follow the prescribed procedures of the instrument manual.
6. For the first time, the laboratory equipment personnel must be operated under the guidance of skilled personnel, and they can be independently operated after being proficient.
7. The laboratory equipment and equipment used in the experiment should be laid out reasonably, neatly arranged, easy to operate, observe and record.
8. Before the electronic laboratory equipment is energized, ensure that the power supply voltage meets the input voltage value specified by the laboratory equipment. The laboratory equipment equipped with the three-wire power plug must be inserted into the power supply socket with protective grounding to ensure safety.
9. When using laboratory equipment, its input signal or external load should be limited to the specified range, and overload operation is prohibited.
10. Optical chemical instruments and their accessories should be handled gently to prevent vibration. Do not touch the surface of the optical glass with your hands. When dust or dirt is found, do not wipe it with your hands or a rag. It must be removed with special products or special tools.
11. Some laboratory equipment should not be used in magnetic or electric fields. Screening measures must be taken to prevent damage to laboratory equipment or to reduce measurement accuracy.
