Drug Rotation Spectrophotometer Touch Screen CHP 0621 Temp Control 15℃-35℃

ST302B Drug rotation spectrophotometer touch screen

The touch screen of ST302B drug optical rotation analyzer is designed and manufactured according to the new version 2025 Chinese Pharmacopoeia 0621 optical rotation analyzer method, mainly used as a specialized instrument for measuring the optical rotation of drugs. Equipped with a touch screen display and cold light sources such as LED, it has a long service life and can detect optical rotation, specific rotation, concentration, and more

Unless otherwise specified, the 2025 Chinese Pharmacopoeia 0621 rotational photometry method uses the D-line (589.3nm) of the sodium spectrum to determine energy intensity, with a measuring tube length of 1dm (if other tube lengths are used, conversion should be made) and a measuring temperature of 20 ℃.

Performance characteristics

Built in Peltier temperature control to improve accuracy and stability.

LED light sources with a lifespan of over 100000 hours compensate for their short lifespan and susceptibility to damage;

To ensure the measurement accuracy of the results, the instrument temperature control technology adopts built-in Peltier instead of traditional flow cells;

The control adopts systematization, high integration, full automation, and is convenient and easy to operate;

Upgrade the measurement range to ± 89 ° (optical rotation), improve the limitations of the measured sample, and enhance the selectivity of the measured sample;

Upgradeable multi-level synchronous retrieval function, which can retrieve historical data based on testing dates, sample numbers, etc.

★ Compliant with 21CFR Part 1 audit trail, pharmacopoeia, and electronic signature (optional)
