General description

Arsenic(III) oxide is a volumetric standard produced under rigorous conditions and measured with the highest possible precision. Its content determination and homogeneity assessment are carried out using volumetric redox titration as the primary analysis method.

Application

The reference material is to be 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
  • Offers accurate titer determinations
  • Accompanied by a certificate of analysis (CoA)

Analysis Note

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