Five operating points of Abbe refractometer, what do you know?

Five operating points of Abbe refractometer, what do you know? Abbe refractometer is an instrument that can measure the refractive index and average dispersion of transparent, translucent liquids or solids (mainly for measuring transparent liquids).
the index of refraction
.

The following are the precautions for the Abbe refractometer shared with you.
Let's take a look
.

 Matters needing attention 1.
Pay attention to protect the prism when using it, and only use lens paper instead of filter paper when cleaning
.

When adding the sample, the mouth of the dropper should not touch the mirror surface
.

Abbe refractometer should not be used for corrosive liquids such as acid and alkali
.

2.
During each measurement, the sample should not be added too much, generally only 2 to 3 drops can be added
.

3.
Pay attention to keep the instrument clean and protect the dial
.

After each experiment, add a few drops of acetone to the mirror and wipe it dry with lens tissue
.

Use two layers of lens cleaning paper between the two prism mirror surfaces to avoid damage to the mirror surface
.

4.
When reading, sometimes the clear dividing line between light and dark cannot be observed in the eyepiece, but it is deformed.
This is because the prisms are not filled with liquid; if there is an arc-shaped halo, it may be because the light does not pass through the prism and is directly irradiated.
on the condenser lens
.

5.
If the refractive index of the sample to be tested is not within the range of 1.
3 to 1.
7, the Abbe refractometer cannot measure it, and the dividing line between light and dark cannot be seen
.

The above is the relevant introduction about the precautions of the Abbe refractometer.
I believe that everyone has a corresponding understanding of it after reading it.
After understanding it clearly, it is necessary to operate it to ensure the accuracy of the test.
I hope it will be helpful to everyone
