Thermo Scientific Orion Star T940 All-in-One Titrators

The Thermo Scientific Orion Star T940 All-in-one Titrators are designed to increase laboratory productivity by automating titrations. This core electrochemistry technology is integrated with a state-of-the art reagent dispensing system to create modern, simplified automated titrators designed to make performing titrations easier, more reliable, and more reproducible. Use the titrator for flexible acid-base, redox, or ion concentration titrations including: titratable acidity of juices and wines, acidity of food products, alkalinity of waters, sulfite/SO2 in juice and wine, ascorbic acid (vitamin C) in food products, chloride/salt in food products.

Titration techniques include equivalence point titrations, preset pH or mV endpoint titrations plus MKA mode for automated known addition of various ions for versatile sample analysis. The automated titrant delivery system with high-accuracy burette and dispenser provides consistent results. Automatic results calculations simplify analysis and reduces computational errors.
