Buffer concentrate for buffer solution acc. to WEISE

半岛bd体育手机客户端 说明

一般描述

The Titrisol^?reference buffer concentrate for buffer solution acc. to WEISE [for 1000 mL of solution (phosphate), pH=7.20] 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, batch-specific Certificate of Analysis.

分析说明

pH-value (20?°C): 7.20 +/- 0.05
Measured after dilution to 1l at 20 °C.
