Abbe Refractometers

It offers easy handling with minimal sample quantities. Krüss offers three models in the Abbe refractometer AR series. They are characterised by their easy handling and minimal sample quantities. These devices allow samples in the form of solids or pastes to be measured just as easily as liquids.

  • These are easy to use and require only a small sample volume.
  • These devices allow samples in the form of solids or pastes to be measured just as easily as liquids.
  • Colouration or clouding scarcely affect the measurement result.
  • Besides the refractive index, the solid content can be determined in %Brix.
  • To determine the refractive index of solids, a contact liquid with an average refractive index is required.
  • Abbe refractometers have thermostat connections on both the illumination prism as well as the measurement prism.
