Anderson liquid FL100
This high quality contact solution is z. B. used for measurements with the gemstone refractometer, for direct determination of the specific refraction of light of a stone. It serves as a high-index contact liquid (connecting medium) between the stone to be measured and the measuring surface of the measuring prism.
■ Contact liquid, eg for gemmological refractometers
■ Refractive index: 1.79 nD
■ Content: 10 ml
How to use the contact solution and practical application examples can be found in the article: Determining gemstones with the refractometer
Background information on the use of refractometers and the use of contact liquid can be found in the Refractometry method article.
