Bellingham and Stanley has published a ‘top tips’ guide to taking refractometric measurements.
These are relevant whether the measurements are Brix, RI, Urea, or any other application specific scale derivatives that have been introduced since Ernst Abbé designed his first refractometer in 1869.
The guide covers the choice of refractometer: dependent on measuring requirements and the environment in which users will be using the instrument, budget and best practice for measuring.
Best practice covers matters such as sample preparation, effects of temperature and application of the right amount of sample.
So whether it’s a simple handheld refractometer for field testing before fruit harvest, or the sort of sophisticated instruments required for a factory environment producing expensive pharmaceuticals, Bellingham and Stanley says the tips will aid users in getting the most from the equipment they choose.
Refractometers are instruments used in both the laboratory and in the field for obtaining a measurement of the index of refraction.
A common application is quality control in a wide variety of industries, from beverages to solvents, in order to ensure product consistency and regulation compliance.
A refractometer therefore has a vital role to play and correct usage can save not just time, but money as well, by preventing the wastage of expensive raw materials or ingredients.
