Abbe Refractometer

Our New Abbe Refractometer Model R-4 with Improved Optics and Eye Piece is a reliable and accurate instrument designed for measuring Refractive Index and Dispersion of Liquids and also determining the Brix of aqueous solutions. This instrument has been specially designed with particular regard to its various applications in Pharmaceutical and Sugar Industry in addition to its suitability in Educational Institutions, Chemical Industries, Research and Test Laboratories etc. Accuracy, ease,and convenience of use along with low maintenance is the special feature of this Refractometer used for Scientific Analysis and Industrial Process Control.

The Refractometer method is an easy and quick method. It requires only few drops of the liquid to be tested to obtain a pin point accuracy of the Refractive Index measurements. The introduction of Water Jacketed Prism Box in this design enables the Refractometer to be connected to a Circulating Thermostat Bath for precise temperature control. For measuring the temperature in the Prism box a Thermometer is also provided. The Instrument employs a day light illuminating system requiring only natural day light. However artificial light can also be used and is recommended. The system incorporates a Compensator to compensate for dispersion of the medium under test. This enables Measurement of Refractive Index in White Light.
