产品说明

一般描�?/p>

The Titrisol^?reference buffer concentrate [boric acid/potassium chloride/sodium hydroxide; pH=11.00��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.

特点和优劾�/p>

• 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.
