Spectrophotometer Principle and Intended Use

UV/Visible spectrophotometers measure the transmission of light through a sample. Samples absorb light based on their unique molecular

composition. The amount of absorbance is directly proportional to the sample concentration and the pathlength, which is the distance that

the light travels through the sample.

UV/Visible spectrophotometers are used in a number of different laboratory environments including life science, clinical, healthcare and

industrial laboratories. In a life science laboratory, UV/Visible spectrophotometers are commonly used to measure the concentration of

nucleic acids and proteins.

Hardware

Your spectrophotometer is a simple-to-use UV/Visible instrument with two silicon photodiodes. A 1200 lines/mm aberration corrected

concave grating mounted on a calibrated motor, which is the basis of the quick and accurate scanning operating system.
