半岛bd体育手机客户端 说明

一般描述

Sodium chloride (NaCl) is a volumetric standard manufactured under rigorous conditions and analyzed with the highest possible precision. The mass fraction of the standard is determined by potentiometric titration, and it is qualified in a DIN EN ISO/IEC 17025 accredited laboratory.

应用

It finds its use as a certified reference material (CRM) for the standardization of volumetric solutions in argentometric titrations, in accordance with USP and Ph. Eur.

特点和优势

• Available as a solid in a contamination-proof glass bottle to ensure its stability for the entire shelf life until opened.
• Certified reference material according to ISO 17034
• High-purity material traceable to SRMs from NIST
• Analyzed in a DIN EN ISO/IEC 17025 accredited laboratory
• In accordance with the chapter reagents of USP and Ph. Eur
• High-quality offering accurate titer determinations
• Accompanied by a certificate of analysis (CoA)

包装

SKU-pack size numbers ending with a "3" are SmartChemicals with an RFID tag on the label for seamless data transfer to the instrument, e.g. xxxxxx1003 or xxxxxxx 4003. More information on www.sigmaaldrich.com/SmartChemicals
