Acid & Base Number
Total Acid Number (TAN) and Total Base Number (TBN) standards are intended for use in the determination of Acid Number and Base Number in petroleum products.
With the CONOSTAN® family of TAN standards, titration curves have more prominent inflection points and higher pH differentials to provide a lower uncertainty for better calibration of titrators and higher precision in test methods.
Each CONOSTAN® TBN standard incorporates unique chemistry to provide a strong levering influence on the titration curve creating dramatic and easy to determine inflection points.
All standards are produced and certified as appropriate to a laboratory quality management system that is accredited to ISO 17025 and ISO 17034.
