STNY-105 Pesticide specific optical rotation tester
The STNY-105 pesticide specific optical 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.
Specific optical rotation: The optical rotation measured by a
specific wavelength of polarized light passing through a 1dm tube
and a 1g/L liquid of light substance at a certain temperature T is
called the specific optical rotation at that wavelength and
temperature.
