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.
