ST302 Drug polarimeter (with constant temperature)

The ST302 drug optical rotation analyzer is designed and manufactured according to the new version 2025 Chinese Pharmacopoeia 0621 optical rotation measurement method, mainly used as a specialized instrument for measuring the optical rotation of drugs.

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 ℃.

Characteristic:

1. Use light-emitting diodes with a lifespan of over 20000 hours as the light source, replacing the previously low lifespan and easily damaged sodium lamps. This greatly eliminates the inconvenience caused by frequent replacement of sodium lamps for users.

2. Adopting photoelectric detection and microcomputer control technology, with a large backlit LCD display, the data is clear and intuitive.

3. Can test optical rotation, specific rotation, concentration, and sugar content

4. Automatic retesting (1-6 times optional), and automatically calculate the average and root mean square.

7. The traditional process of using copper worm gears and counting discs will not result in missing characters during long-term use.
