The Zuzi model 418 automatic digital polarimeter is a high-precision optical analysis instrument, designed for the determination of optical rotation in optically active substances, even in samples with very low transmittance. Equipped with advanced electronic technology and microprocessor control, it allows for automated measurements with high reliability and repeatability.
The equipment executes three consecutive measurement cycles with automatic calculation of the average value, improving the accuracy of the results and reducing operator intervention. Its detection system allows working with samples with a minimum transmittance of 1%, which makes it a particularly effective solution for complex analyses where other equipment presents limitations.
It incorporates a monochromatic light source of 589.3 nm using LED technology, providing spectral stability and long service life. The reading resolution reaches 0.001°, with a measurement range of ±45°, ensuring exceptional precision in demanding analytical applications.
The magneto-optical modulation system based on the Faraday effect optimizes the equipment's sensitivity, allowing precise detection of small variations in optical rotation. The results are displayed on a five-digit digital screen, facilitating direct reading and reducing interpretation errors.
It is compatible with 100 mm and 200 mm measurement tubes, adapting to different types of samples and analysis protocols. Additionally, it has an RS232 interface for data transfer and integration into laboratory management or control systems.
This polarimeter finds application in chemical and pharmaceutical laboratories, research centers, and quality control, being used for the determination of concentration, purity, and composition of substances such as sugary solutions, essential oils, organic compounds, and chemical derivatives.
With dimensions of 620 × 340 × 250 mm, the model 418 combines robustness, precision, and advanced technology, positioning itself as a reference tool for high-demand polarimetric analyses.
