一般描述
The Titrisol® reference buffer concentrate [phosphate; pH=7.00±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.
