REFRACTIVE INDEX SOLUTION 1.79
A 2ml bottle of Refractive Index Fluid with a Refractive Index itself of 1.79, suitable for use with our Refractometer selection and virtually any other Gem Refractometer.
RI fluid allows your refractometer to measure within the measuring range of 1.30 to 1.80 Refractive Index.
Perfect for testing ALL of your stones! As the name implies, it is widely used with gem refractometers as a contact medium for the identification of gemstones. RI liquid can also be used to reduce or eliminate glare from a gem's surface, facilitating inspection of the gem's interior for inclusions and other defects.
This refractive index fluid is packed and will be supplied in a special spill resistant bottle.
To guarantee the liquids maximum shelf life, keep this liquid securely sealed after opening, and remember to place the vial in areas which are protected from direct light and in a dry environment with moderate temperature.
RI fluid is toxic and should not be inhaled. If it comes into contact with bare skin or eyes wash thoroughly with plenty of fresh water.
