Metallic Body Abbe Refractometer for Solids

The Abbe Refractometer is a precision optical instrument designed to measure the refractive index (nD) and dispersion (nF–nC) of liquids, solids, and semi-solids with high accuracy. Widely used in chemical, pharmaceutical, food, and petrochemical industries, it operates on the principle of total internal reflection, allowing for accurate determination of purity, concentration, and quality control parameters.

This refractometer typically offers a measuring range of 1.3000 to 1.7000 nD, with a least count or resolution of 0.0001. It includes a built-in thermometer and a water jacketed prism assembly to maintain a constant temperature, generally 20°C or 25°C, using an external circulating water bath. The device consists of a graduated scale with Vernier reading, adjustable mirror system, and collimating lens to provide clear and sharp demarcation for precise readings.

Constructed with a heavy-duty metallic body, the Abbe Refractometer ensures stability and durability during laboratory use. It is particularly useful for quality analysis of sugar solutions, oils, solvents, and other transparent or translucent substances, and remains a trusted tool for research laboratories, academic institutions, and industrial quality control departments.
