What Is Cuvette

Dec 03, 2021

A cuvette is an equipment used for spectroscopic analysis. It is mainly a quartz cuvette fired from quartz powder, but also cuvettes for trace, semi-micro, fluorescent, etc.

Cleaning method

1. Wash with a mixture of ether and absolute ethanol (50% each).

2. If it is too dirty, it can be cleaned with a special lotion. But the time should be short (10 minutes), and then rinse with clean water.

Precautions

The cuvette is generally a rectangular parallelepiped, the bottom and both sides of which are ground glass, and the other two sides are made of optical glass. The light-transmitting surface is made of fusion, glass powder high-temperature sintering and glue bonding. Therefore, pay attention to the following points when using::

1. When taking the cuvette, you can only touch the ground glass on both sides with your fingers, and avoid touching the optical surface. At the same time, pay attention to handle with care to prevent the influence of external force on the contrast plate and damage after stress.

2. Any solution containing substances that corrode glass should not be stored in a cuvette for a long time.

3. Do not place the cuvette on a flame or electric furnace for heating or baking in a drying box;

4. When it is found that the inside of the cuvette is contaminated, clean it with absolute ethanol and wipe it clean in time.

5. Do not touch the light-transmitting surface of the cuvette with hard or dirty objects. When holding the solution, the height is 2/3 of the cuvette. If there is residual liquid on the optical surface, it can be lightly absorbed with filter paper, and then wiped with lens paper or silk.
