Computer Controlled Three Dimensions (31) Physics
If you’re doing manual titration, it’s time to switch gears
Manual titrations are time consuming and can be inaccurate at times due to human error. Not to mention, important data can get easily lost due to improper tracking methods. The Thermo Scientific Orion Star T900 series automated titrators are designed to make performing titrations easier, more reliable and more reproducible than manual titrations. These automated titrators expand the number of ions and compounds that can be measured beyond direct electrode analysis and offer dynamic process controls that adjust the titration to optimize analysis results.

Best practices using automated titrators. Achieving speed and accuracy in your lab.
