Product Description

Visual Polarimeter with Sodium Lamp Auto Polarimeter for Optical Rotation Analysis Optical Disk Polarimeter

Introduction

The Visual Polarimeter is a laboratory instrument used for measuring the optical rotation of substances, which is the ability of a substance to rotate the plane of polarization of light. This rotation is due to the differential absorption of left and right circularly polarized light by the molecules of the substance. Visual Polarimeters are commonly used in education, research, and industrial applications, particularly in the fields of chemistry, biology, pharmaceuticals, and food science.

Applications

1. Chemical Analysis: Used to determine the purity and configuration of organic compounds, especially those with optical activity.
2. Pharmaceutical Quality Control: Ensures the purity and consistency of pharmaceutical ingredients.
3. Food Science: Measures the sugar content and other components in food, such as the purity of honey.
4. Biochemical Research: Studies the structure of proteins, nucleic acids, and other biomacromolecules.
5. Education and Training: Used in teaching laboratories to demonstrate the phenomena of light polarization and optical rotation.

Principle

The working principle of a Visual Polarimeter is based on the rotation of the plane of polarization of light as it passes through an optically active substance. Here are the detailed steps of its working principle:

1. Light Source: The instrument typically uses a stable light source, such as a sodium lamp, to produce polarized light.
2. Polarizer: The light from the source first passes through a polarizer that only allows light waves of a specific direction to pass through, thus producing polarized light.
3. Sample Tube: The polarized light passes through a sample tube containing the substance to be tested. If the sample is optically active, it will cause the plane of polarization of the light to rotate.
4. Visual Observation: The rotated polarized light then passes through a second polarizer (analyzer), which can be rotated to align with the rotated light's plane of vibration. The observer adjusts the analyzer until the light is completely extinguished (i.e., no light is visible) by looking through an eyepiece.
5. Measurement of Rotation Angle: By measuring the angle through which the analyzer is rotated, the optical rotation of the sample can be determined. This angle is usually expressed in degrees (°) and is related to the concentration of the sample and the path length.
