A refractometer is a laboratory device used to measure the refractometry i.e. index of refraction of liquid samples and to measure the concentration of the liquid such as sugar content, protein content, and salinity. Refractometers also used to calculate serum water concentration. Refractometers are especially used to determine urine specific gravity of veterinary samples as they require relatively small sample volumes. Veterinary refractometers are majorly used for the testing of colostrum ... Read more
