What is a spectrophotometer?
A spectrophotometer is an analytical instrument used to measure the absorption and transmission of light by a sample. It operates in the ultraviolet, visible and infrared ranges and enables the precise determination of the concentration of substances in solutions.
What a spectrophotometer measures: the intensity of light before and after it passes through the sample. Based on this data, the optical density and the concentration of the analysed components are calculated.
What is a spectrophotometer used for: quantitative and qualitative analysis in chemistry, biology, pharmaceuticals and medicine. A spectrophotometer in the laboratory is an essential instrument for routine and research tasks.
