Fisher Scientific Abbe Bench-Top Refractometer for Effective Measurement of Refractive Indices

The Fisher Scientific™ Abbe Bench-top Refractometer measures refractive indices of liquid and solid samples at D-line (589nm), featuring a combination of the Brix and refractive index (nD) scales.


Abbe refractometers are named after Ernst Abbe, who invented the first refractometer in the 19th century. Despite the emergence of modern-day digital models, these original refractometers remain irreplaceable due to their unique ability to measure solid samples, such as film, glass, and other transparent materials.
