Do I need to purchase a bottle of refractive index oil for my refractometer? If so can you point me in the right direction to make sure I get the right product that is needed.
Thank you,
Kandace,
Not sure why your message was never answered. Hopefully you have found the R.I. fluid necessary but if not… JTV is currently selling it for $71.12! Which is about $20 dollars less than Amazon!

National industrial supply also has RI fluid at a very reasonable price. $19.99 1.800 12 Gram Gem Gemstone Refractometer Refractive Index Fluid – NISupply
