Item Description: 10 Gram Vial of 1.81 Refractive Index for Gem Refractometers
American Made and ARSENIC FREE!
The most important aspect of the Refractometer is the quality of the fluid and its Refractive Index.
This product has a Refractive Index value of 1.81RI and is THE best product for accurate GEM Identification.
The 10 Gram Vial holds about 2.5ml of product
The Gem Refractometer Liquid has a refractive index of nD = 1.810, the highest of any liquid not containing arsenic. As the name implies, it is widely used with gem refractometers as a contact medium for the identification of gemstones. This light yellow 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 liquid is supplied in an amber glass bottle. The cap has a glass applicator rod attached to it on the inside, designed to deliver a small droplet.To ensure the liquids maximum shelf life, keep this liquid tightly sealed after opening, store it away from direct light and in moderate temperatures.
