effect both taste and shelf life. 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
