A tool invented in 1869, Abbe refractometers are a highly useful scientific instrument. First developed to measure the refractive nature of liquids, its inventor, Ernst Abbe, wanted to see just how much light bent within various liquids. Using his newly-invented instrument, he started categorizing various liquids into a refractive index. In the 150 years since
A Bausch & Lomb Abbe-3L Refractometer. Introduction. A refractometer measures the extent to which light is bent (i.e. refracted) when it moves from air into a sample and is typically used to determine the index of refraction (aka refractive index or n) of a liquid sample. The refractive index is a unitless number, between 1.3000 and 1.7000 for .The Abbe Refractometer derives its name from the 19th Century physicist Ernst Abbe (1840-1905). Abbe designed an instrument for measuring the dispersion of light and this became the precursor for the so-called ‘Abbe Refractometer’.9.3 Auto Abbe Refractometer Operation Guide1. 1. Turn on unit from switch on back of instrument. 2. Turn on water pump next to instrument 3. Let instrument warm up for at least 10 minutes 4. Select Mode “nD” or nD-TC (refractive index temperature compensated 5. Calibrate place water on prism using plastic pipette and
Abbe’s Refractometer . The Abbe instrument is the most convenient and widely used refractometer, Fig(1) shows a schematic diagram of its optical system. The sample is contained as a thin layer (~0.1mm) between two prisms. The upper prism is firmly mounted on a bearing that allows its rotation by means of the .ABBE REFRACTOMETER PRECISION MODEL The NAR-3T was developed to give improved measurement accuracy and ease of use. This was achieved by making fundamental improvements to the optical system, utilizing a lager scale, incorporating a high intensity lamp and using a double control knob to give quick and more accurate control. 1 .High accuracy .
In the late 1990s, Abbe refractometers with the capability to read at wavelengths other than the standard 589 nanometers became available. These instruments utilize special filters of the desired wavelength of light, well into the near infrared (though a special viewer is required to see the infrared rays). .

Prudent Practice. Reporting Results. Analyzing Results. Additional Resources. Theory. The speed of light in a vacuum is always the same, but when light moves through any other medium it travels more slowly since it is constantly being absorbed and reemitted by the atoms in the material.
The VEE GEE Model C10 Abbe Refractometer is an excellent instrument for the Refractive Index (nD) analysis of liquids, glass, plastic, & film.
