THE WORLD OF REFRACTOMETRY Whether it is the pharmaceutical, chemical, food or beverage industry, the producers of aromas, scents and essential oils, the petrochemical, metalworking or the automobile industry – refractometers play an important role in all of these industries to provide quality assurance. They determine the refractive index of liquid or solid substances from which you can deduce their identity and quality as well as their concentration in binary or quasi-binary mixtures. It also allows you read the progress of reactions and material conversions. Refractometers are used in a number...

FOCUS ON QUALITY WITH REFRACTOMETERS FROM A.KRÜSS

DIGITAL REFRACTOMETERS – DR6000-T MODELS MEASURING ALL LIQUIDS AND PASTES We developed the digital refractometers of the DR6000 model series in close cooperation with well-known partners from industry and research. They deliver highly accurate and reproducible measurement results, offer the option to work semi and fully automatically and are easily integrated into existing processes in the laboratory. There are four different models available for different requirements on accuracy, resolution and measurement range whereby you can access the same operation and functionality. The refractometers...

DIGITAL REFRACTOMETERS – DR6000 MODELS MEASURING SUGARY SAMPLES The DR6000 models are especially suited for highly accurate measurements of products from the sugar industry. All their features are identical with our DR6000-T models but do not feature an internal Peltier temperature control. Instead of temperature control, the temperature compensation according to ICUMSA can be used. With the help of this already implemented conversion function, the concentration level [% Brix] at the measuring temperature is converted (compensated) to the value at a standard temperature of 20 °C. If needed, our...

AUTOMATION OPTIONS – DR6000-TF MODELS SAMPLE SUPPLY OPTIONS MANUAL FULLY AUTOMATIC When working manually with the DR6000 and DR6000-T models, the low-viscous to highly viscous samples are added into the measuring tray with a pipette, syringe or spatula. The measuring tray is then closed with a sample cover. The cleaning is effortless: Apply cleaning agent to the measuring tray and wipe it off using a soft cloth until all sample residues have been dissolved and removed. The semi-automatic operation requires the DR6000-TF models with flow-through function, flow-through measuring cell, drying unit...
