Ancient Rome, the state centered on the city of Rome from 753 BC through its final eclipse in the 5th century AD. In the course of centuries Rome grew from a small town on the Tiber River in central Italy into a vast empire that ultimately embraced England, most of continental Europe, and parts of Asia and Africa.

Compared to many other instruments in the laboratory or factory, using a refractometer is a very simple process. In most cases you apply a small sample to a cleaned refractometer and take a reading. That’s it! As easy as that is, and as rugged as a refractometer can be, regular verification is always recommended to maximise the accuracy of any readings .The VEE GEE Model C10 Abbe Refractometer is an excellent instrument for the Refractive Index (nD) analysis of liquids, glass, plastic, & film. . The MA886 digital refractometer uses the refractive index to determine sodium chloride concentration in aqueous solutions used in food preparation. The MA886 is not designed for measuring salinity in .
A Refractometer works because light travels at different velocities in different mediums, the light beam is bent at the interface between two adjoining materials.This is called “refraction”. There is an angle of light propagation at which refraction no longer occurs, the light beam instead being reflected back into the original material.
Correction values for sucrose solutions measured on the Brix (% Sucrose) scale are shown in the table below. The correction values should be added to the scale reading. Example: An Abbe 5 gives a reading of 35.4° Brix at a temperature of 32° C Scale reading of instrument = 35.4 Correction = 0.99 Equivalent value at 20°C = 36.39 which should beUnless otherwise noted, the Palm Abbe refractometer is temperature compensated for aqueous (water-based) sucrose solutions.The temperature coef ficient of most aqueous solutions is generally close to that of sucrose; howeve, the temperature coer ficient of oils, f hydrocarbons, and other non-aqueous solutions is generally large. r

In the Abbe' refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism (Figure 2). The refracting prism is made of a glass with a high refractive index (e.g., 1.75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism.
High accuracy may be achieved with both Abbe and Digital Automatic refractometers. The latter are generally more expensive instruments and tend to be favoured by quality control laboratories. Bellingham+Stanley offers a wide range of refractometers covering all the types described above. The RFM Automatic Digital Refractometers are used by manyThe Palm Abbe refractometer has a wider range and twice the accuracy of the Pal-1. Compare the Palm Abbe to refractometers costing more than ,000. Digital Accuracy Digital refractometers remove the subjectivity associated with reading traditional refractometers.

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 The refractometer readout shown above is measuring 30 degrees Brix. Other Types of Refractometers. Digital refractometers require a drop of the tested solution to be placed in a well. That well is illuminated by a light source, usually an LED light, and the meter interprets the light transmission into refractive index or whatever unit of measure the .

Digital refractometers often feature built-in temperature compensation and user-friendly interfaces, making them suitable for laboratory use and quality control applications. Abbe Refractometers. Abbe refractometers utilize a prism and a collimated light source to measure refractive indices across a wide range of wavelengths.The initial version of the Abbe refractometer was upgraded by the German company Carl Zeiss [14]. In latest version of automatic Abbe refractometer, water bath has been replaced by in-built Peltier to heat or cool. Temperature control, refractive index reading display and export of data can be easily controlled through a computer.
