Buffer concentrate

半岛bd体育手机客户端 说明

一般描述

The Titrisol^?reference buffer concentrate [citrate/hydrochloric acid; pH=4.00±0.02 (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
