AGRI-1-2-UV-VIS Spectrophotometer
A UV-VIS Spectrophotometer is a laboratory instrument used to measure the spectrum of light absorption or transmission in the ultraviolet (UV) and visible (VIS) regions. It operates by passing a beam of light through a sample and measuring the intensity of the transmitted or absorbed light, providing insights into the chemical composition, concentration, and physical properties of the material. The device consists of a light source (deuterium lamp for UV and tungsten lamp for visible light), a monochromator to isolate specific wavelengths, a sample holder (often a cuvette), and a detector that converts optical signals into electrical data. Common applications include analytical chemistry for determining concentrations of compounds via Beer-Lambert's law, biochemistry for detecting proteins or nucleic acids, environmental studies for monitoring pollutants, and pharmacology for analyzing drugs and active ingredients. Its advantages include rapid operation, high precision, and the ability to work with small sample volumes, making it an essential tool in scientific research and industrial quality control.
