Manual Polarimeter 404

The Zuzi model 404 manual polarimeter is an optical measuring instrument designed for determining the rotation of polarized light in substances with optical activity. Its manual operation and intuitive design make it a versatile solution for laboratories in the chemical, pharmaceutical, food, and academic sectors.

The equipment has two graduated scales with a range of ±180° and a resolution of 1°, complemented by a vernier system that allows a reading accuracy of up to 0.05°. This system reduces eccentricity errors and improves accuracy in interpreting results.

It incorporates a light source based on a low-pressure sodium lamp with a wavelength of 589.4 nm, providing optimal conditions for measuring optical rotation. The sample compartment is inclined and accommodates tubes up to 220 mm in length, offering flexibility for different types of analyses.

The optical system includes an eyepiece with dioptric adjustment and 4x lateral magnifying glasses that facilitate reading the scales, improving ergonomics and precision during use. Zero calibration is performed using macrometric and micrometric controls, allowing fine adjustments before each measurement.

The equipment is supplied with 100 mm and 200 mm sample tubes, covering typical laboratory analysis needs. Its robust structure, with a weight of 7.5 kg and dimensions of 480 × 135 × 325 mm, ensures stability during operation.

This polarimeter allows determining parameters such as concentration, purity, and composition of optically active substances, being especially useful in the analysis of sugar solutions, essential oils, organic compounds, and industrial products.

Thanks to its reliability, precision, and ease of use, the model 404 is a fundamental tool for optical analysis work in environments where control and accuracy are required without the need for automation.
