  • Check the compatibility of the polarimeter with other laboratory instruments and data systems.

Frequently Asked Questions

What is a polarimeter used for?
A polarimeter is used to measure the angle of rotation of polarized light passing through a substance, often used in chemical analysis.
How does a polarimeter work?
A polarimeter works by passing polarized light through a sample and measuring the resultant angle of rotation.
What industries use polarimeters?
Polarimeters are commonly used in the pharmaceutical, chemical, food, and beverage industries for quality control and research.
What is optical rotation?
Optical rotation refers to the rotation of the plane of polarized light as it passes through certain substances.
