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’.
Bellingham Stanley offer a number of Abbe refractometers and a choice can be made in accordance with the measurement requirement and budget availability.
Launched in 2006, the Abbe 5 offers direct refractive index and Brix readings at a low price and is ideal for academia as well as for general measurement within industry.
Abbe 60 refractometers are manufactured to extremely high standards and come in a variety of scale ranges to suit particular application requirements including regular single wavelength refractive index and high accuracy dispserion measurements.

Automatic refractometers are used in the food and beverage industry, in chemistry, pharmacy and many other branches for measurements of refractive index (nD) or of refractive index-derived concentrations. Refractive index measurements are fast, non-destructive and require only a small volume of sample. No extensive sample preparation is necessary.
The latest generation of Abbemat refractometers sets new standards regarding accuracy and versatility.
Due to modern data processing and innovative optical design a resolution of 0.000001 nD is achieved. The measuring ranges are 1.32 to 1.56 nD (HP model) and 1.30 to 1.72 nD (WR model), allowing refractive index measurements of organic solvents, perfumes and aromas.
Within an interval of 10-70 °C an internal Peltier thermostat adjusts the temperature of the measuring prism at an accuracy of ±0.03 °C, so that no additional external thermocirculator is required. The stability of the temperature adjustment is ±0.002 °C.
The measuring unit is housed in a water-proof enclosure made of stainless steel containing the optics and the electronics of the instrument. Its small size saves valuable bench space in the laboratory.
A personal computer is used as an intelligent terminal offering easy operation combined with best performance. From a continuously growing number of scales the required scale can be selected or be defined by the user. User management, several measuring modes, easy calibration possibilities as well as GLP-conform data recording round up the features of the Abbemat.
Different types of sample cells are offered, allowing the adaptation of the instrument to every task in the laboratory. |

Pursuing the "easy-to-use" and "easy-to-understand" ergonomic architecture of this new instrument, the achieved result was not only a "palm fitting" design but also a unit with highly hygienic properties. By reducing the number of unnecessary assembly parts such as the grip, we cut down the risks of creating a germ reproductive enviroment.Though our effort to pursue a germ-free unit, it is unavoidable for an instrument to have grooves between each component and shutting completely the way for germs to spread, so we have come up with new concept of making it a completely washable unit. Moreover, it is equipped with the E.L.I. function, which makes the measurement more reliable in bright light area.

Refractometry is an ideal analytical procedure for an accurate and reliable measurement of a liquid's purity, concentration or density. The primary measured quantity is the refractive index of the liquid.
The measurement is independent of the liquid's turbidity and color, nor is it influenced by entrained gas bubbles. No minimum flow rate is necessary.
Refractometers are widely used for monitoring or regulating concentration as well as for quality control. They are a very common in laboratories where for example they are used for quality spot checks.
PIOXR R operates on the basis of the transit-light principle: it measures the refractive index of light transmitted through the liquid, thus not simply by measurement of a thin layer of liquid on a prism, as it is done in the critical angle method. The latter is used by most other common refractometers. The transit-light method has the advantage that the entire liquid serves as a sample. Measurement by the transit-light principle is drift free and can reach a precision which is by a factor 10 higher than that of conventional refractometers.

Optilab® rEX Refractive Index Detector
2005 R&D 100 Award Winner!
The Optilab® rEX (refractometer with EXtended range) is an Refractive Index detector with 256 times the detection power and up to 50 times the dynamic range of every RI detector in existence today. Using a combination of cutting-edge semiconductor photodiode technology and proprietary computer algorithms, the rEX presents a host of instrument firsts.
For example, there are no range or gain settings. The full range of instrument detection is always present, and the full sensitivity exists over the entire range.
The rEX also has a flow cell with a total volume of only 7.4 uL -- 25% less than the leading refractometers available today. This translates into minimized band broadening and better temperature stability.
The Optilab® rEX can also do something no other on-line Refractive Index detector can: it can measure the absolute refractive index of a solution. In addition, it can measure the dn/dc of a solvent at the same wavelength of light as the light scattering instrument. And just to make sure it can't be matched, you can replace the light source in the rEX for other wavelengths (e.g. 690, 633, 488, etc.)!
The new Optilab® rEX shares the ability its predecessor (the Optilab® DSP) to go to below ambient temperatures as easily as above ambient. No hassle temperature control can be programmed down to 4°C or as high as 50°C. Compatible with all HPLC systems. |
