Refractometers

A.KRÜSS refractometers measure the refractive index of liquids, pastes and solids with high precision. In close cooperation with well-known partners from industry and research, we have developed refractometers that can be easily integrated into existing processes in the laboratory.

Refactometer applications

Refractometers are used for quality assurance in the pharmaceutical, chemical, food and beverage industries as well as in the production of flavours, perfumes and essential oils or in the petrochemical, metalwork and automotive industries. Generally speaking, the determination of the refractive index helps to examine the purity of a substance quickly and reliably. In addition, the progress of reactions and substance conversions can be read via the refractive index.

Typical applications
 

Automation with refractometers

The DR6000-TF models with through-flow function, flow-through cell, drying unit DS7060, peristaltic pump DS7070 and autosampler AS80 or AS90 allow for semi- or fully automated operation.
