STNY-105B Pharmaceutical Testing Instruments State-of-the-Art Instrument for Measuring Specific Rotation

The STNY-105B pesticide specific rotation meter is designed and manufactured in accordance with the NYT 1860.18-2010 Guidelines for Testing the Physical and Chemical Properties of Pesticides Part 18: Specific Rotation Method. It is a specialized instrument for measuring the specific rotation of pesticides. Using touch screen display and LED or other cold light sources, it has a long service life and can detect optical rotation, specific rotation, concentration, etc
Specific optical rotation
At a certain temperature T, the specific rotation of polarized light at a specific wavelength passing through a 1dm light tube and a 1g/L liquid of light substance is called the specific rotation at that wavelength and temperature.
