Rudolph Research Analytical Calibration

Refractometer Calibration Standards

Rudolph Research Analytical works with Cargille Laboratories to provide a range of refractometer calibration standards.

All Calibration standards are:

  • Supplied in 28ml bottles
  • Supplied with a calibration certificate traceable to the National Institute of Standards and Technology (NIST)
  • Shelf life of unopened bottle is 5years
  • Shelf life of opened bottle is 2.5 years
  • Fluids calibrate at temperatures between 20°C and 40°C are accurate to 0.0001 Refractive index
  • Fluids calibrate at temperatures above 40°C are accurate to 0.0005 Refractive index
  • Some fluids available with calculated Brix values
  • Some fluids available with claculated Urine Specific gravity numbers
