General description
Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.
Potassium hydrogen phthalate, also known as KHP, is a volumetric standard produced under stringent conditions and measured with the highest possible precision. The content of the standard is measured using volumetric acid-base titrations. Its certified value and uncertainty measurement are in accordance with ISO Guide 35.
Application
It finds its use as a reference material for the standardization of volumetric solutions in alkalimetric 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-purity material traceable to NIST SRM
- High-quality offering 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.
