Spectrophotometer

A spectrophotometer is a scientific instrument that measures the amount of light of a specified wavelength which passes through a medium. According to Beer’s law, the amount of light absorbed by the medium is proportional to the concentration of the absorbing material or solute present. Marshall Scientific always has spectrophotometers in stock made by notable brands such as Agilent, Milton Roy, and Beckman. All of Marshall Scientifics spectrophotometers are tested to perform at factory specifications. Please view our inventory of spectrophotometers and feel free to give us a call or send us an email if you have any questions.
