"This refractometer is super easy to use. It can be set up in a matter of minutes and has customizable methods that can be created for your specific analysis. Getting an extra two decimal places for RI greatly improves our ability to detect very small differences between samples. Also, temperature equilibration is quick and reproduceable. If you are in the market for a user-friendly RI instrument, check this model out!"
