1. The electron microscope is a relatively fragile instrument. The important part of the electron microscope is the lens. The lens should not be dropped. It should be handled with care when putting it, and it should be kept in a safe place after use. To ensure the cleanliness of the laboratory.

2. If conditions permit, it can be placed in a dust-free environment. There should be no dust in the laboratory to prevent dust sticking to the lens and affecting the observation effect. Keep the air dry, ventilate frequently, or use air conditioning. If the laboratory is too humid, the lens of the electron microscope will corrode.

3. Don't place it in a place with vibration. Often in a place with vibration, it will easily lead to inaccurate viewing and affect the observation effect, so try to keep it in a fixed place for observation.

4. The voltage of the electron microscope should also keep the input voltage at 220V and the input voltage at 5V. The fluctuation should not be too large. If it is too large, it may cause the microscope to burn out. The temperature should be between 0 degrees and 30 degrees.

5. Non-professionals cannot disassemble the core part of the scanning electron microscope. The light source of the electron microscope is also very important. Ensure that the brightness is always constant. Do not increase and decrease suddenly, which will affect the observation effect and cause eye fatigue. After using the light source, turn it off. You can't directly turn on the plug. Turn off the switch first, and then turn on the power supply.

6. When the electron microscope is used up, the magnification must be adjusted to a low state, so that it is convenient for the next use, and the second is to ensure the accuracy of the lens.

7. Pay attention to the bracket of the electron microscope, don't move it randomly, don't put the dust cover on immediately after use, let the temperature of the microscope and light source drop, and then put it on the cover (dustproof). I emphasize once again that if there is a technical problem that cannot be solved, it must not be dismantled privately, and it should be solved by a professional. Pay attention to the above points, and the service life of the electron microscope will be prolonged.
