How to maintain biological microscope
7 ways to maintain a biological microscope:
High heat, moisture, dust, corrosion, shock, wipe, other
1. Anti-high fever of biological microscope
The biological microscope is composed of precise mechanical and optical lenses. Due to the different thermal expansion coefficients of various materials, the microscope cannot be exposed to sunlight or placed near the stove and heating. It can only be stored at room temperature. The working temperature range is generally 5 ℃ ～ 40 ℃.
Second, the biological microscope moisture
If the biological microscope is exposed to moisture for a long time, the lens is prone to mold and the surface will corrode, so it should be stored in a dry environment. in
Humidity must not be greater than 80% at 31 ° C. When the temperature increases by 3 ° C, the relative humidity must be reduced by 10%.
3. Dustproof of biological microscope
Biological microscope dust not only affects the imaging quality, but also often contains corrosive dust particles containing acids, alkalis, etc., which is easy to corrode the mirror surface. The dust particles with high hardness may also scratch the lens surface and damage the lens when wiping the lens. In addition, when dust falls into the moving parts of the machine, it is easy to cause the machine parts to rotate inflexibly or even be damaged.
4. Anti-corrosion of biological microscope
Biological microscopes should not be exposed to acids and alkalis, and should not be placed with highly volatile chemicals or other harmful chemicals to avoid corroding the lens.
5. Shockproof biological microscope
Biological microscopes are precision instruments, and severe vibration will cause a decrease in precision. It should be handled gently and placed on a stable surface, and the movement should be gentle when in use.
6. Wiping with biological microscope
1. If there are stains on the mechanical device, it can be wiped with a clean soft cloth; if it cannot be wiped off, it can be wiped with a small amount of xylene with lens paper or fine silk cloth. It should be noted that alcohol, ether and other chemicals should not be used to avoid corrosion of the paint on the surface of the device.
2. The wiping of the optical lens generally adopts the method of first blowing, then brushing, and then wiping. Blowing is to blow off the attachment on the surface of the lens with a balloon (or ear wash), but you cannot blow it directly by mouth. When you can't blow it off, you can gently brush it with a clean special cleaning brush. When there are still dirt on the surface of the lens after the above two treatments, use lens cleaning paper slightly dipped in a little xylene to gently wipe. If you find that the lens is moldy and foggy, you can wipe the lens paper with a little mixture of absolute alcohol and ether, but the liquid should not be too much, and the residence time should be short to prevent it from penetrating into the lens and causing corrosion. The oil lens should be wiped in time after each use. First wipe the lens with dry lens paper once or twice to remove most of the medium oil, then wipe the lens paper twice with xylene wet wipes, and finally wipe it again with dry lens paper .
7. Biological Microscope Other
Do not touch the surface of the optical lens of the biological microscope to avoid contamination. After using the device with tension, let it return to its natural relaxed state. It is best not to let it be in an extreme position for any adjustable part. Do not switch the power switch frequently within a short time. Decrease the brightness of the light during use of the microscope. Never leave specimens on the stage for a long time, especially when volatile substances are present.
