General description

Calcium carbonate volumetric standard is manufactured under stringent conditions and measured with the highest possible precision. The standard is qualified by volumetric complexometric titration with photometric endpoint detection. 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 complexometric titrations.

Features and Benefits

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