Introduction
Manual Disc Polarimeter is a basic scientific instrument used to measure the optical rotation of optically active compound solutions with an accuracy of 0.05 degrees. It has a sample chamber tube with a length of up to 200 mm and sealing rings. A high performance 589 nm sodium lamp with a long service life is used as a light source. It is a simple manual polarimeter with a measuring range of -180 to +180° that requires little maintenance.
Applications
It is an ideal device for measuring the concentration of liquid samples in various fields of research and teaching, pharmaceutical and chemical industries, food and sugar industry and other industry applications.

FAQs
1. How does a Manual Disc Polarimeter work?
It passes polarized light through a sample, and the user manually adjusts a rotating disc to determine the angle of rotation, which indicates the optical activity of the substance.
2. What is the difference between a Manual and Digital Polarimeter?
A Manual Disc Polarimeter requires manual adjustment of the disc to measure optical rotation, while a Digital Polarimeter provides automated readings with digital display and higher accuracy.
3. Can a Manual Disc Polarimeter be used for sugar analysis?
Yes, it is commonly used in the sugar industry to measure the optical rotation of sugar solutions and determine their concentration.
4. Does a Manual Disc Polarimeter require calibration?
Yes, periodic calibration with standard solutions ensures accurate and reliable measurements.
5. What light source is used in a Manual Disc Polarimeter?
Our Manual Disc Polarimeter uses a sodium lamp for consistent and precise optical rotation measurements.
