Condition: Brand new
Item Description: 1.8ml Vial of 1.81 Refractive Index for Gem Refractometers (this vial is about HALF full)
American Made and ARSENIC FREE!
THIS IS THE BEST FLUID AVAILABLE FOR GEM REFRACTOMETERS!
This product is the non-poisonous version of the classic Gem Refractive Index Fluid; Diiodomethane (methylene iodide).
This product is also made in the USA!
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 4.0ml vial has an applicator rod inside the cap for easy application and holds 1.8ml of fluid. The "10 Gram Vial" only has about 2.5ml!
This is a better deal on a per ounce basis!
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 by a highly reputable American supplier in bulk and repackaged in an amber glass bottle. The cap has a plastic 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.
