General description

Search & download your certificate here.
Sodium oxalate is a volumetric standard produced under stringent conditions and analyzed with the highest possible precision. The content determination and homogeneity assessment of the reductometric standard are carried out using volumetric redox titration as the primary analysis method.

Application

The reference material is used as a reductometric standard for titer determinations in redox titrations.

Features and Benefits

  • Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
  • Traceable to NIST standard reference material
  • 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.
