Refractometers are essential instruments in many laboratories, used to measure the refractive index of liquids or solutions. This measurement allows scientists to obtain key information about the concentration of solutes dissolved in a solvent, such as sugars, salts, or other substances. Refractometers are widely used in fields such as the food industry, chemical research, medicine, and the beverage industry, where precision is necessary to ensure product quality and accurate results.

These devices operate on a basic physical principle: the deviation of light when it passes from one medium to another with different density. The refractometer measures how the light angle changes when it passes through the solution, allowing for the calculation of the refractive index, a value that correlates with the concentration of the solute in the liquid. In summary, refractometers are key tools for laboratories that require precise measurements of purity, concentration, or quality of solutions.
