We offer the clients a wide range of Laboratory Polarimeter (CPM Series), which is appreciated for its innovative, compact design and long life. We are among the credible Manufacturers, Exporters, and Suppliers of Laboratory Polarimeter (CPM Series).
The polarimeter have 589.44nm sodium lamp. After powered on, the polarized light, beam is immediately radiate to the filter, polarizer etc. You can observed distinct visual fields through eyepiece of instrument. Put the sample tube into measuring field chamber. Rotate the vernier knob again, you can view equal brightness. Read the scale from magnifier that is measured value.
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.
If you want to know sample’s purity, you need only measure it's the angle of rotation and calculate it.
For substance of known specific optical rotation, you can measure it's the angle of rotation and calculate concentration according to formula.
International Sugar Scale
According to international sugar scale, put the 26grams pure sugar in solution, The angle of rotation of solution is 34.626o. By the rules, you can calculate the purity of sugar.
