Mettler Toledo’s Excellence line of density meters, refractometers and titrators coupled with the InMotion autosampler provide a unique, fully automated measuring system for the efficient analysis of beverages. The InMotion autosampler greatly reduces workload and increases efficiency in the quality control laboratory. Using the new InMotion autosampler, allows one to determine Brix (density and/or refractive index) and pH simultaneously, and even acidity of juices and beverages, in a single run. The system can also be combined with an Excellence titrator to measure acidity in parallel and to calculate the acidcorrected Brix value. When working with carbonated beverages, the InMotion autosampler automatically degasses samples prior to measurement. Stirring at different speed levels, air is blown to the bottom of the beaker, ensuring quick, efficient and repeatable degassing. The InMotion autosampler also can perform a variety of testing, cleaning and conditioning processes. Users can reduce sample carry over with the PowerShowe
