Description

General description

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.

Application

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

Features and Benefits

• 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)

Analysis Note

Exact concentration, expiry date, traceability and detailed information on certification can be found on the certificate and certification report, included in each package. Content and expiry date on label.
