Laboratories are important places for experimental teaching and research. Experimental teaching is an important way to cultivate students' scientific literacy and practical ability. So how to maintain laboratory equipment for a long time to ensure the normal use of instruments and equipment?
1. Daily cleaning
The cleaning of laboratory equipment plays a very important role in its normal operation and service life. During long-term use, a certain amount of dust, dirt and stains will accumulate on the surface of the equipment, which will affect the normal operation of the equipment and reduce the accuracy and stability of the equipment. Therefore, it is necessary to clean the equipment regularly and wipe the surface of the instrument with a clean soft cloth regularly to remove dust, dirt and stains. For parts that are prone to dust accumulation, such as the heat dissipation holes and buttons of the instrument, special attention should be paid to cleaning. When cleaning, mild detergents and soft cloths should be used, and rough or corrosive substances should be avoided to avoid damaging the surface of the instrument. At the same time, the laboratory environment should be kept clean to avoid dust, debris, etc. from contaminating the instrument.
2. Regular calibration
The precision and accuracy of experimental instruments have a great influence on the experimental results, so the instruments need to be calibrated regularly. The frequency of calibration should be determined according to factors such as the type of instrument, usage and accuracy requirements. Generally speaking, for instruments with higher accuracy requirements, calibration should be performed once a year; for instruments with lower accuracy requirements, calibration can be performed every two or three years. Calibration should be performed by professional technicians to ensure the accuracy and reliability of calibration.
3. Regular replacement of wearing parts
There are many wearing parts in laboratory equipment, such as filters, rubber tubes, sealing rings, etc. These wearing parts will have aging, wear and other problems during long-term use, affecting the normal operation of the equipment. Therefore, it is necessary to check the condition of these wearing parts regularly and replace them in time.
4. Regular inspection
Regular inspection of experimental instruments and equipment is an important part of maintenance. The inspection content includes the appearance, performance, accuracy and other aspects of the instrument. Through regular inspection, problems with the instrument can be discovered in time, and corresponding measures can be taken for repair and maintenance to avoid the expansion of problems and affect the normal use of the instrument.
5. Regular maintenance
During the long-term use of the equipment, some faults and problems are inevitable, so it is necessary to regularly maintain the equipment to ensure the normal operation and service life of the equipment.
Through regular maintenance and care of instruments and equipment, the normal operation and accuracy of the equipment can be guaranteed, the reliability of experimental results can be improved, and a strong guarantee can be provided for the smooth development of laboratory work. The above simply lists some measures. The specific measures still need to be planned and implemented by school laboratory managers according to the actual situation. Everything is based on reality to ensure the safety of the laboratory.
