A spectrophotometer is an instrument used to measure the amount of light that a sample absorbs. It works by passing a light beam through a sample to measure the light intensity of a sample. These instruments are used in the process of measuring color and used for monitoring color accuracy throughout production. In analytical laboratories, a spectrophotometer is used for the identification and quantifying microscopic samples such as matching colors, kinetics, qualifying gems and minerals

Wear a lab coat, safety glasses, gloves, etc. as required for the experiment. students are required to wear safety equipment

Instruction: 

1. Please bring your own cuvette, tissue, apparatus and glassware.
2. Get permission from PIC before use.

The uses of a spectrophotometer are as follows:

• A spectrophotometer is used for the quantitation of nucleic acid (DNA or RNA).
• It determines the concentration of color and colorless compounds by measuring the absorbance of the solution. ...
• Similarly, it determines the phase of reaction by measuring the formation and disappearance rate of the light-absorbing compounds in the range of the visible and UV region of the electromagnetic spectrum.
