General description

The amount of sugar in an aqueous solution is measured in degrees Brix (symbol °Bx). One gram of sucrose in 100 grams of the solution equals one degree Brix, which measures the solution′s strength as a percentage of its weight (%w/w).


  • Refractive index standard for use as a calibration standard in determination of Brix value by refractometers
  • The use of this standard for determining sugar content is also possible in the wine and beer, sugar, fruit juice, honey, starch, and sugar manufacturing industries.

Features and Benefits

  • Each product has five ampoules, and each ampoule contains an 8ml solution
  • Accompanied by technical data sheet that includes information about extended measurement uncertainty calculated according to ISO 17025
  • Traceable to recognized national standards, and to units of measurement recognized at the National Institute Standards and Technology (NIST) and Physical Technical Institute (PTB)
  • Solutions that are stable, ready to use, and have long minimum shelf lives.
