Cargille Labs Refractive Index Certified Water
NIST/ASME uses as the authority for the properties of water, the publication issued by IAPWS ( The International Association for the Properties of Water and Steam ). The IAPWS has published the "absolute" refractive index of water, that is relative to a vacuum. We have calculated its refractive index, relative to air, by dividing the Absolute Refractive Index of water by the Absolute Refractive Index of air ( references available ).
ACS Reagent Grade Water was measured for refractive index at 589.3 nm on a high precision Abbe type refractometer standardized with NIST traceable standards.
*Note refractive index of water at 589.3 nm +/-0.00005 is equivalent to 0.000 % Brix +/-0.035
|Temperature Degrees Celsius +/-0.01
||Absolute Refractive Index of Water +/-0.00005 at 589.3 nm
