LWXG-5 semiautomatic polarimeter used to measure angle of rotation, specific optical rotation of optically active substance. You can calculate its purity, concentration and percentage by measured value.
Microprocessor-Based The angle of rotation is digitally displayed Simple push-button adjustment of visual fields
Zero indicator light confirms accurate calibration
Specific Optical Rotation Measurement:
Specific optical rotation is constant of substance, you can measure it by 100mm glass tube when temperature of solution at 20oC.
The polarimeter is ideal for determining purity of sample. If you want to know its purity, you need only measure its the angle of rotation and calculate it.
For some substance of known specific optical rotation, you can measure its the angle of rotation and calculate concentration according to formula.
International Sugar Scale:
According to international sugar scale, put the 26g pure sugar in solution, The angle of rotation of solution is 34.626o. By the rules, you can calculate the purity of sugar.
