How to maintain an optical biological microscope
1. Anti-high heat of biological microscope
Biological microscopes are composed of precise mechanical and optical lenses. Due to the different thermal expansion coefficients of various materials, the microscope cannot be exposed to sunlight, nor can it be placed near the stove and heating. It can only be stored at room temperature, and its working temperature range is generally 5°C to 40°C.
2. Moisture-proof biological microscope
If the biological microscope is damp for a long time, the lens is easy to mold and the surface will be corroded, so it should be stored in a dry environment. exist
The humidity should not be >80% at 31°C, and the relative humidity should be reduced by 10% for every 3°C increase in temperature.
3. Biological microscope dustproof
Biological microscope dust will not only affect the imaging quality, but also often contain corrosive dust particles such as acid and alkali, which are easy to corrode the mirror surface. The hard dust particles may also scratch the mirror surface and damage the lens when wiping the lens. In addition, when dust falls into the mechanical moving parts, it is easy to cause the mechanical parts to rotate inflexibly or even be damaged.
4. Anti-corrosion of biological microscope
Biological microscopes should not be in contact with acids and alkalis, and should not be placed together with highly volatile chemicals and other harmful drugs, so as not to corrode the lens.
5. Shockproof biological microscope
Biological microscopes are precision instruments, and severe vibrations will reduce precision. It should be handled with care, shelving should be stable, and the action should be gentle when using.
6. Biological Microscope Wipe
1. If there is any stain on the cleaning mechanism of the mechanical device, it can be wiped with a clean soft fine cloth; if it cannot be wiped off, it can be wiped with a small amount of xylene with lens cleaning paper or fine silk cloth. It should be noted that alcohol and other chemicals should not be used, so as not to corrode the paint on the surface of the device.
2. The cleaning of the optical lens generally adopts the method of blowing first, then brushing, and then wiping. Blowing means blowing off the attachments on the surface of the lens with a blower (or ear wash ball), but you cannot blow directly with your mouth. When it cannot be blown off, it can be gently brushed with a clean special cleaning brush. If there is still dirt on the surface of the lens after the above two methods, use a lens cleaning paper slightly dipped in xylene to wipe it gently. If you find that the lens is moldy and foggy, you can wipe it with a mixture of lens cleaning paper dipped in a little absolute alcohol, but the liquid should not be too much, and the residence time should be short, so as not to penetrate into the lens and cause corrosion. Oil lens should be wiped in time after each use, first wipe it once or twice with dry lens paper to remove most of the medium oil, then wipe it twice with xylene wet lens paper, and finally wipe it with dry lens paper once.
7. Biological Microscope Others
The surface of the optical lens of the biological microscope cannot be touched by hand to avoid contamination. After using the device with tension effect, let it return to the natural relaxation state. Anything that is adjustable is best left out of its extreme position. Do not switch the power switch frequently in a short period of time. Reduce the brightness of the light when the microscope is in use. Never leave the specimen on the stage for a long time, especially when there are volatile substances.
