RI Fluid - Premium

0.80 LBS
  • Product Description

    Select here for a 10 gram bottle of Refractive Index Fluid with a Refractive Index itself of 1.81, suitable for use with our Refractometer selection and virtually any other Gem Refractometer.

    The reason that RI fluid is used with a Refractometer is to create what is called "optical contact" with the gemstone being measured.

    This bottle's screw cap has a built-in glass rod for dipping just the right amount of fluid on the refractometer glass, as shown in the photo.ristick.jpg 

    This fluid is packaged for safety, with a sealed cap, a copper clad oversized bottle, and a label detailing proper safety procedures.

    This product typically ships within 1 business day.
