WebThe refractometer works by shining a beam of light through a sample of liquid. The device measures the amount of light that is refracted (or bent) from the light path due to the constituents in the sample. In blood, proteins will cause light to bend. The greater the protein, the more light is bent from the light path. WebThe refractometer is a measuring device for determining the refractive index of transparent substances in liquid or in some cases also in solid state. It is used to observe the …

WebA 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 to determine the concentration using mixing rules such as the Gladstone–Dale relation and ...
