Laurent's Half Shade Polarimeter
Item Code : SK018
Principle and Working:
Laurent’s Half-Shade Polarimeter is an optical instrument used to measure the optical rotation of chiral substances. It improves accuracy with a half-shade plate, which enhances brightness comparison for precise readings. Commonly used in chemistry, pharmaceuticals, and the food industry, it helps determine the concentration and purity of optically active solutions.
- Polarimeter function can be carried out precisely in an economical unit.
- Sturdy metal housing and modular construction.
- Sodium source can be used in vertical & horizontal positions
- Modern and user friendly design.
- Least count 1°
- To study the principle of operation of a Half-shade polarimeter.
