    Overview

    This liquid is required for use with the Eickhorst® Standard Refractometer and the System Eickhorst® GemLED Refractometer. It eliminates air between the stone and glass so that optical contact is established between the two surfaces. Such contact is necessary to obtain a reading from the instrument.
