Cargille Refractometer Standards - 19400


Cargille refractometer standards come with a letter of NIST traceability certification. Calibrate your refractometer with either oil or water.

Cargille refractive index oil is standardized at 589.3 nanometers (D line) and 25°C and has temperature coefficients and dispersion values listed on the label.

Cargille refractive index certified water uses ACS reagent grade water measured for refractive index at 589.3 nm on a high precision Pulfrich, standardized with NIST traceable standards.
