General description

Di-sodium oxalate is a volumetric standard manufactured under stringent conditions and measured with the highest possible precision. Its mass fraction is determined by potentiometric titration, and it is qualified in a DIN EN ISO/IEC 17025 accredited laboratory.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

In our effort to be more sustainable, we′re going digital with COAs-download them directly from our website. Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.

Application

It is used as a certified reference material (CRM) for titer determinations in redox titrations, according to reagents chapters of USP and Ph. Eur.

Features and Benefits

Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
Certified reference material according to ISO 17034
High-purity material traceable to NIST standard reference materials
Qualified in a DIN EN ISO/IEC 17025 accredited laboratory
In accordance with the chapter reagents of USP and Ph. Eur
High-quality offering accurate titer determinations

Packaging

SKU-pack size numbers ending with a "3" are SmartChemicals with an RFID tag on the label for seamless data transfer to the instrument, e.g. xxxxxx1003 or xxxxxxx 4003. More information on www.sigmaaldrich.com/SmartChemicals
