Calibration Liquids

Refractive Index Certified Water

ACS Reagent Grade Water was measured for refractive index at 589.3 nm on a high precision Pulfrich, standardized with NIST traceable standards

Cat.#: 19400

Refractive Index for 589.3 nm light:
@ 20°C – 1.33297 ±0.00005
@ 25°C – 1.33249 ±0.00005
@ 30°C – 1.33193 ±0.00005

Cargille’s MTCL is very stable and non-toxic. It can be used in forensic identification of glass using a GRIM or similar system.
The refractive index was read on a high precision Pulfrich, standardized at each temperature using NIST Standard Reference Material 1823 I.
Temperature Coefficient dn/dt = -0.000393 °C
