Analysis Note

pH-value (20 °C): 5.00 +/- 0.02Measured after dilution to 500 ml with a combination glass electrode after multiple point calibration (according to DIN 19268) with reference materials for the preparation of standard buffer solutions according to DIN 19266.

Features and Benefits

Traceable to primary standard reference materials from NIST and PTB Analytical standard Grade Uncertainty data and traceability are documented in a comprehensive and batch-specific Certificate of Analysis.

General description

The Titrisol^® reference buffer concentrate [citrate/sodium hydroxide; pH=5.00±0.02 (20 °C)] is analyzed in the ISO/IEC 17025 accredited calibration laboratory with a combined glass electrode and 5-point calibration according to DIN 19268 against a certified primary standard reference material following DIN 19266.The Titrisol^® concentrated buffer material combines ease of use and maximum precision for the routine calibration and monitoring of pH instruments. To prepare the ready-to-use pH buffer solution, simply dilute the Titrisol^® buffer concentrate.
