A spectrophotometer is an instrument used to measure the amount of photons (the intensity of light), the transmission or reflection of visible light, UV light or infrared light absorbed after it passes through sample solution. It is determined by measuring the intensity of light detected, measures intensity as a function of light source wavelength.

Used in Used in high requirement for precision measurement in the research, production of organic chemistry, suitable for quantitative determination assays, toxicological assays in environmental, medical testing, food testing, biochemistry, water testing industries, environmental protection, industrial, pharmaceutical field.

Also known as Vis Spectrometer, UV-Vis Spectrometer, Spectrometers, visible spectrophotometer.
