Ultraviolet-Visible (UV-Vis) Spectrophotometer is laboratory equipment used for measuring the absorbance and transmittance of light in the ultraviolet and visible regions of the electromagnetic spectrum. It is commonly used in various scientific fields, including chemistry, biochemistry, and molecular biology.
UV-Vis Spectrophotometers operate by directing a beam of light at a sample, measuring how much of that light is absorbed or transmitted by the sample, and then using that information to determine the concentration of the substance in the sample. The amount of light absorbed or transmitted depends on the chemical composition of the sample, which makes it useful for identifying the presence of a particular substance.
UV-Vis Spectrophotometers have a wide range of applications, including the analysis of DNA and protein samples, the detection of impurities in pharmaceuticals, and the measurement of the concentration of various compounds in solution. They are also commonly used in quality control and research and development in a variety of industries, such as food and beverage, environmental monitoring, and materials science.
Overall, UV-Vis Spectrophotometer is an essential tool for any laboratory that requires accurate and precise measurement of the absorbance and transmittance of light in the UV and visible regions of the electromagnetic spectrum.
