How to do the maintenance of biological microscope?

How to do the maintenance of biological microscope? These points you need to know Nowadays, microscopes are becoming more and more common in our lives, and how to do a good job in the maintenance of microscopes has become a topic of concern to many people
.

So, how should the biological microscope be maintained? Let’s take a look at the key points with the editor below
.

1.
The placement of the biological microscope should be in a dry and clean room to avoid mold on optical parts, rust on metal parts and dust
.

After the microscope is used, put it back into the box (cabinet), or cover it with a glass cover or a plastic cover, and put in a dry cleaning agent
.

2.
Do not disassemble the parts by yourself; the lens barrel should be plugged into the eyepiece or the shackle cap to prevent dust from entering from the upper part of the lens barrel; the lens surface should not be touched or wiped with your fingers.
If there is dust, first use a soft brush to lightly Flick it off, and then wipe it with a soft cleaning cloth.
You can also try to wipe it with a lens paper dipped in a little xylene or oil, but be careful not to draw streaks on the surface of the lens
.

If there is mild mildew on the lens, if it cannot be wiped off with wiping paper, you can use a cotton swab dipped in a little mixture of 70% ethanol and 30% acetaminophen to gently wipe it off
.

 　　3.
The biological microscope should not be placed together with corrosive acids, reducing or volatile chemicals, so as to avoid corrosion and shorten the service life
.

In principle, when observing specimens containing liquid, a cover glass should be covered; if the liquid contains corrosive chemicals such as acid and alkali, the surrounding area of ​​the cover glass should be sealed with paraffin or Vaseline, and then observed.

.

However, since this type of reagent is often used in microscopic identification, it is impossible to seal it all, so special care must be taken to prevent the liquid from flowing onto the stage and not to get on the objective lens
.

 　　4.
The biological microscope should not be exposed to direct sunlight, nor should it be placed near the stove or heating, to avoid the degumming, deformation or damage of the lens and parts caused by excessive heat and cold changes
.

 　　5.
Cleaning the objective lens is limited to the outer surface
.

After the contact surface is contaminated with medicine, wipe it with a lens paper dipped in a little lens cleaning solution (do not use ethanol); if the back surface needs to be cleaned, use a soft brush to wipe it, or use a leather tip to absorb the dust
.

 　　6.
When turning the thickness adjustment ratio of aluminum focusing, the action should be slow, and do not crush the cover quilt to prevent the objective lens and the concentrator from being damaged by controlled strikes
.

 　　7.
After using the oil lens, the cedar oil on the lens must be wiped clean (you can wipe it with a lens paper dipped in a little xylene, but make sure that the xylene cannot penetrate into the interior of the lens, otherwise the xylene will dissolve the adhesive between the lenses.
, which can cause the lens to fall off)
.

 　　8.
The mirror surface of the reflector should be protected and clean, and do not allow water, xylene or cedar oil to penetrate, so as to prevent the mercury from falling off the reflector
.

 　　9.
The mechanical part is not flexible, you can use a fine silk cloth dipped in xylene: wipe off the rust and greasy (do not use ethanol, because these solvents will corrode the paint), and then lubricate with a little liquid stone clothing; do not force it if the twist is too tight twist to avoid damage
.

 　　10.
Sometimes stains or foreign objects are found in the field of view of the biological microscope.
You can turn the eyepiece first.
If these stains rotate, it can be determined that the stain is on the eyepiece; otherwise, the specimen can be moved.
If the stain moves, the stain is on the specimen sheet
.

If neither, the stain is on the objective lens, pick up the front lens of the food scope first, then check the rear lens
.

Clean according to the situation
.

 　　Sometimes part of the field of view is not clear.
This may be due to fingerprints or dust on the surface of the front lens of the objective lens or eyepiece.
It may also be due to poor specimen preparation or improper use of the microscope.
For example, the lighting system is not properly adjusted.
solved separately
.

 　　11.
After the biological microscope is used, all parts should be wiped clean, the grid-connected objective lens should be turned into a figure-eight shape, then the lens barrel and the light collector should be lowered and fixed, and then the mirror surface of the reflector should be placed in a vertical position
.

 　　The above is the relevant introduction about the maintenance points of biological microscopes.
I believe that everyone has a corresponding understanding of this after reading, and I hope it will be helpful to everyone
