Abbe refractometers. Abbe refractometers are manually operated instruments that can either come in benchtop or handheld form. Samples are sandwiched between a refracting and an illuminating prism. Light illuminates a portion of the sample, and the user aligns a cross-hair with the shadow line, thus deriving a measurement.
Made of high-grade silicone rubber, the Rubber Armor Jacket is custom fit and will help protect your refractometer from minor bumps and scratches. The form-fitting Rubber Armor Jacket fits the Palm Abbe PA201, PA202, and PA203 refractometers and comes in your choice of black, gray, or safety orange.The Reichert Abbe Mark III is the new standard-bearer of Abbe-style manual refractometers. The Mark III continues the tradition of quality, durability, & reliability established by the Mark II. The Abbe Mark III has many advanced upgrades, including menu-driven operation, LCD display, and internal LEDs for long-life illumination.Hand-held refractometer. A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).The index of refraction is calculated from the observed refraction angle using Snell's law.For mixtures, the index of refraction then allows the concentration to be determined using mixing rules such as the Gladstone–Dale relation and .The model C10 Abbe Refractometer is an excellent instrument for the Refractive Index (nD) analysis of liquids, glass, plastic, and film. Operation consists of placing a sample on the prism; while looking through the eye-piece, the control knob is .
Abbe designed an instrument for measuring the dispersion of light and this became the precursor for the so-called ‘Abbe Refractometer’. Bellingham + Stanley offer a number of Abbe refractometers and a choice can be made in accordance with the measurement requirement and budget availability.

Zeiss began advertising Abbé refractometers in 1881. The inscriptiion on this example reads “N˚ 148 Carl Zeiss Jena” and “Germany.” Zeiss records indicate that it was delivered to J. W. Queen & Co., an important instrument dealer in Philadelphia on July 2, 1890. Queen sold it to the Department of Chemical Engineering at the University .The Abbemat refractometers can be connected to other Anton Paar instruments, e.g. to measure density, optical rotation, or viscosity alongside refractive index and concentration. With the Performance Plus line refractometers you can automate sample filling and measurement of up to 96 samples with a sample changer or use an optional built-in .
Abbe Refractometer This instrument measures the refractive index and mean dispersion values of transparent and translucent liquids or solids. Refractive indices and mean dispersions are important optical constants of a substance and can be used to determine the optical performance, purity, concentration and dispersion etc.
