Spectrophotometer Cuvettes

Quantity:

Cuvette is a kind of equipment for spectral analysis. It is mainly made of spectrosil material, there are also micro,semi-micro spectrophotometer cuvettes. It can be cleaned by special ultrasonic wave. When washing spectrophotometer cuvettes the ground side is facing down.Cuvette are filled with samples,usually diluted or suspended in liquid,and placed within a spectroscopy device,such as a colorimeter,fluorometer or spectrophotometer.


Cleaning:

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

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

3.Selection of cleaner,don't use detergents. In order to avoid affecting the measurement.

Spectrophotometer cuvettes are usually cuboids with ground surfaces on the bottom and both sides, and transparent surfaces on the other two sides are made by melting, high temperature sintering of spectrosil powder and glue bonding. 


So we should pay attention to the following points when using:

1. When picking up the spectrophotometer cuvettes, you can only touch the ground surface on both sides with your fingers to avoid contacting the optical surface. At the same time, attention should be paid to light handling to prevent the impact of external forces on the cuvette, resulting in stress and damage.

2. Solutions containing corrosive substances shall not be kept in spectrophotometer cuvettes for a long time.

3. The spectrophotometer cuvettes should not be heated or baked in a drying oven on a flame or electric furnace.

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

5. The transparent surface of the spectrophotometer cuvettes should not be contacted with hard or dirty objects. When filling the solution, the height of the spectrophotometer cuvette is 2/3. If there is any residual liquid on the optical surface, it can be absorbed gently with filter paper, and then wiped with lens paper or silk.


If there is any doubt about the spectrophotometer cuvettes, it can be detected by itself. The method is as follows:

1. Users can set the wavelength selection on the actual wavelength, inject a set of spectrophotometer cuvettes into distilled water, adjust the transmittance of one of them to 100%, and measure the transmittance of the other ones. If the difference of transmittance is not more than 0.5%, it can be used together.

2. Before colorimetric analysis, the spectrophotometer cuvettes were filled with distilled water and compared under the colorimetric wavelength. Four to eight spectrophotometer cuvettes with tolerance within (+0.001) were selected for colorimetric determination, which could avoid the measurement tolerance caused by the difference of spectrophotometer cuvettes.
