Polarimeter
Polarimeter Description
A polarimeter is a precision scientific instrument used to measure the angle of rotation caused by optically active substances. It is widely used in chemical, pharmaceutical, food, and research laboratories to analyze the concentration and purity of compounds such as sugars, acids, and essential oils. Polarimeters work on the principle of polarimetry, where plane-polarized light passes through a sample and the angle of rotation is measured.
Modern polarimeters combine accuracy, speed, and ease of use, making them essential tools for laboratories focused on quality control, research, and industrial applications.
