TAN & TBN Standards

Conostan total acid number (TAN) and total base number (TBN) standards provide coverage over an extensive range of mg KOH/g concentrations to ensure you always have the right standard available for your application. When compared to alternative available products in the market, the titration curves for the Conostan family of TAN/TBN standards consistently have more dramatic inflection points and wider differences between the starting pH and final pH during the titration making data easier to interpret and improving reproducibility.

• Prominent, easy to determine titration inflection point, even at low concentrations
• Quick equilibration of the potential resulting in faster titrations
• Excellent repeatability and reproducibility for ASTM D664 & ASTM D2896

Total acid number and total base number are important measurements in petroleum products. Achieve the most accurate calibration of your titrator and higher precision when performing test methods with Conostan TAN and TBN standards.
