YJ-7100J Fully Automatic Constant Temperature Polarimeter

A polarimeter is an instrument used to measure the optical rotation of substances. By determining the optical rotation, it is possible to analyze and ascertain the concentration, content, purity, etc., of substances. It is widely used in industrial sectors such as sugar production, pharmaceuticals, petroleum, food, chemical engineering, as well as in related universities and research institutions. The use of an LED as the light source eliminates the need for frequent replacement of sodium lamps. The built-in temperature control device features both heating and cooling functions. If a temperature-controlled sample tube is used, the optical rotation of the sample can be measured under controlled temperature conditions. The large LCD screen on the instrument provides a user-friendly menu-driven operation interface, making it simple, intuitive, stable, and reliable.
