Description générale
Potassium dichromate is an oxidimetric standard produced under stringent conditions and measured with the highest possible precision. Its content determination and homogeneity assessment are performed using volumetric redox titration as the primary analysis method.
Application
It finds its use as a reference material for the standardization of volumetric solutions in redox titrations.
Caractéristiques et avantages
- Available in a neat format in a secure glass bottle to ensure its stability for the entire shelf life until opened.
- Traceable to NIST SRMs
- High-quality offering accurate titer determinations
- Accompanied by a certificate of analysis (CoA)
Remarque sur l'analyse
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.
