Classic Abbe refractometer

Classic Abbe refractometer is the article on this page. Luminix Health distributes Krüss for laboratory use. It sits in Refractometers & polarimeters, inside Spectroscopy & photometry, in Instrumenten.

A refractometer reads the refractive index of a liquid, often expressed as Brix for sugar. A polarimeter reads the rotation of polarised light. Both depend on temperature. A handheld refractometer and a thermostated benchtop instrument are different accuracies.

A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.

The category is Spectroscopy & photometry. The sub-category is Refractometers & polarimeters. The catalogue is Instrumenten.

Shelves beside this one are Photometers & spectrophotometers and Lamps, cuvette holders & accessories.
