产品说明
一般描述
The Titrisol® reference buffer concentrate [phosphate/sodium hydroxide; pH=12.00±0.05 (20 ℃)] 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.
特点和优势
- 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.
分析说明
pH-value (20 °C): 12.00 +/- 0.05
Measured after dilution to 500 ml with a combination glass elektrode after multiple point calibration (according to DIN 19268) with reference materials for the preparation to standard buffer solutions according to DIN 19266.
