Definition : Refractometers used for determining the specific gravity and the amount of solute in a solution by measuring the index of refraction. These instruments usually include a monochromatic light source. Laboratory refractometers are mostly used in the field of medicine to measure the concentration of analytes, such as total proteins in plasma and total solids in urine. Some laboratory refractometers include temperature-compensation chambers to make corrections in the refractive index according to the room temperature.
