The Abbe refractometers have a wide range of applications in the chemical, petro-, oil- and fat industries, in the food industry, in hospitals, pharmacies and research offices, as well as in research and teaching. The special feature is the possibility to measure not only liquid and viscous samples but also solids and foils.

Main application fields are:

  • Identity test, purity control and concentration determination of raw materials, semi-finished products and end products
  • Determination of the sugar concentration
  • Incoming and outgoing goods inspection
  • Purity control
  • Testing of food and pharmaceutical products
  • Testing of the compliance with national and international standards
  • Training
