Refractometer Uses in Industry and Selection By Angelo DePalma, PHD A refractometer characterizes fluids based on their refractive index –the refraction occurs due to the change in the speed of light as it travels through a material of one density to one of different density. By definition a vacuum has a refractive index of 1, […]

Refractometer Temperature Correction & Control Peter Marriott – Refractometer Product Manager Rudolph Research Analytical Also see video: Refractometer, Temperature Correction & Control with a Rudolph J457 We are going to look at the effects of changing temperature on refractive index measurement and if Temperature Correction can compensate for temperature variances or if actual temperature control […]
The refractometer is easy to use and easy to clean. We are looking forward to many years of trouble free operation.
The lab technicians like it for its ease of use, and the lab supervisors (myself included) like it for its reproducibility from one technician to the next…
