Polarimeters

Polarimeter

Automatic & Manual Models

Polarimeters 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. Measuring the angle of rotation 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. A.KRÜSS Optronic manufactures a variety of polarimeters to suit your laboratory needs, from industry and R&D to education.
