Optical Polarimeters

Polarimeter instruments measure the angle of rotation of optically active substances. The measurement of the angle of rotation is an important quality control measurement and is commonly used in the pharmaceutical, chemical, cosmetic and food & beverage industries. Optical rotation measurement allows you to ascertain the identity and quality of substances as well as their concentration in mixtures. It can also indicate the progress of a reaction and conversions. For more information about optical rotation Polarimeter technology and applications, click here to visit the KRÜSS Optronic Campus.
