Beschreibung

Allgemeine Beschreibung

Sodium chloride (NaCl) is a volumetric standard manufactured under rigorous conditions and analyzed with the highest possible precision. The content of the standard is measured by volumetric argentometric titration and the measurement can be traced back to NIST SRM. Its certified value and uncertainty measurement are in accordance with ISO Guide 35.

Anwendung

It finds its use as a certified reference material (CRM) for the standardization of volumetric solutions in argentometric titrations.

Leistungsmerkmale und Vorteile

• Available as a solid in a contamination-proof glass bottle to ensure its stability for the entire shelf life until opened.
• High-purity material traceable to SRMs from NIST
• High-quality offering accurate titer determinations
• Accompanied by a certificate of analysis (CoA)
