Potentiometric Titrator - Automatic Touch Screen Titrator - 10/20 mL Burette - ±0.005 pH Accuracy

The Master Science Potentiometric Titrator performs potential titration analysis from a 7-inch colour touch screen. The method, the titration curve and the results are shown live, and a formula editor turns the end point straight into the reported value.

A replaceable high-accuracy burette of 10 mL or 20 mL doses the titrant with 1/50000 resolution. The tubing withstands acids, alkalis, perchloric acid and organic reagents, so non-aqueous titrations can be run as well as aqueous ones.

Common Problems and How This Titrator Helps

How the Master Science Potentiometric Titrator improves on manual titration:

• Colour end points judged by eye: potentiometric detection.
• Coloured or turbid samples: electrode signal instead of indicator.
• Aggressive titrants damaging tubing: corrosion-resistant burette line.
• Hand calculations and transcription: formula editor and file export.
