The Zuzi model 412 digital automatic polarimeter is an optical analysis instrument designed for the precise determination of optical rotation in substances with optical activity, especially in samples with low rotary power. Its photoelectric detection technology allows automatic measurements with high sensitivity and without manual intervention, facilitating the obtaining of reliable and reproducible results.
The equipment uses a monochromatic illumination source based on a sodium lamp with an optical filter at 589.4 nm, which guarantees stable measurement conditions and adequate resolution in the analysis of optically active compounds. Its measurement capacity covers a range of ±45°, with an accuracy of ±0.01°, allowing highly precise work in demanding analytical applications.
The system incorporates direct digital reading and automatic data processing, including multiple measurement functions with average calculation, which improves the reliability of the results. Its sensitivity allows the analysis of samples with a minimum transmittance of 10%, expanding its applicability compared to conventional equipment.
It is compatible with 100 mm and 200 mm sample tubes, offering flexibility depending on the type of analysis. In addition, it has an RS232 communication interface for data transfer and integration into registration or control systems.
This polarimeter is widely used in chemistry laboratories, the pharmaceutical industry, quality control, scientific research, and academic environments, where the determination of parameters such as concentration, purity, or composition of optically active substances is required, including sugar solutions, essential oils, and organic compounds.
With dimensions of 600 × 320 × 230 mm and 220 V electrical power supply, the equipment combines structural robustness with advanced functionality, constituting a reliable solution for high-precision polarimetric analysis.
