How to Maintain the Dilun Optical Biological Microscope
1, Biological microscope for preventing high heat
A biological microscope is composed of precision mechanical and optical lenses. Due to the different coefficients of thermal expansion of various materials, the microscope cannot be exposed to sunlight or placed near a furnace or heater. It can only be stored at room temperature, and its working temperature range is generally 5 ℃ to 40 ℃.
2, Moisture proof biological microscope
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. at
At 31 ℃, the humidity should not exceed 80%. For every 3 ℃ increase in temperature, the relative humidity should be reduced by 10%.
3, Dust prevention of biological microscope
Dust from biological microscopes not only affects imaging quality, but also often contains corrosive dust particles such as acids and alkalis, which can easily corrode the mirror surface. Dust particles with high hardness may also scratch the mirror surface and damage the lens when wiping it. In addition, dust falling into mechanical moving parts can easily cause the mechanical parts to rotate inflexibly or even be damaged.
4, Corrosion prevention of biological microscope
Biological microscopes should not come into contact with acidic and alkaline substances, and should not be placed together with highly volatile chemicals or other harmful drugs to prevent lens corrosion.
5, Shock resistant biological microscope
Biological microscopes are precision instruments, and severe vibrations can cause a decrease in precision. Handle with care, place steadily, and use gently.
6, Biological microscope wiping
If there are stains on the wiping device of the mechanical device, a clean soft cloth can be used to wipe it off; If it cannot be wiped off, you can use mirror paper or a fine silk cloth dipped in a small amount of xylene to wipe it off. Attention should be paid not to use chemicals such as alcohol to avoid corroding the paint on the surface of the device.
The wiping of optical lenses generally adopts the method of blowing first, then brushing, and then wiping again. Blowing refers to using a balloon (or an ear wash ball) to blow off the attachments on the surface of the lens, but not directly blowing air through the mouth. When it cannot be blown off, a clean specialized cleaning brush can be used to gently brush it. When there are still dirt on the surface of the lens after the above two methods of treatment, gently wipe it with a lens wiping paper dipped in a little xylene. If the lens is found to be moldy and foggy, it can be wiped with a mixture of wiping paper dipped in a small amount of anhydrous alcohol, but the liquid should not be too much and the residence time should be short to avoid penetrating into the interior of the lens and causing corrosion. After each use, the oil lens should be wiped in a timely manner. First, use dry wiping paper to wipe once or twice, remove most of the medium oil, then wipe twice with xylene dripping wet wiping paper, and finally wipe once with dry wiping paper.
