Liquid refractive index measurement
Do you want to measure the refractive index of your samples? The Calnesis Laboratory performs these measurements with precision tools in a wide temperature range.
What is the refractive index of a liquid?
A liquid’s refractive index (n) characterizes its ability to deflect light passing through it by changing the direction of light waves from what they were in air. Thus, the greater this index, the more the liquid deflects the light passing through it. This index depends on the temperature, pressure and composition of the sample, as well as the wavelength of the incident light. Its determination allows for example:
- identify a species and check its purity
- determine the composition of a mixture (using a calibration)
The refractive index is a data used in particular for quality control.

Refractive index measurement method
The measurement is carried out using a precision electronic refractometer, the temperature of which is regulated by a thermostated circulating bath.
Other measurements
Measurements of solid/liquid contact angles using a temperature-regulated optical bench.
