Description
- General description: The certified buffer solution (boric acid/sodium hydroxide/hydrogen chloride) is gravimetrically prepared using high-quality reagents following DIN EN ISO/IEC 17025. Its pH value of 8.00 at 20°C is measured following a 5-point calibration method, using a combined glass electrode. The measurement is made following DIN 19268 using reference buffer solutions compliant to DIN 19266, NIST, IUPAC, Ph. Eur, and USP. Its pH value is strongly dependent on the temperature and therefore a constant temperature must be maintained during its use.Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.
- Application: The buffer solution is meant to be used as a calibration standard in analytical procedures for pH measuring instruments or pH electrodes and as a control for measuring the pH of solutions.
- Features and Benefits: Measured and qualified at an ISO/IEC 17025 and ISO 17034 accredited laboratoryTraceable to secondary reference standard from NIST and primary certified reference standard from PTB Ready-to-use solution Available in a sealed plastic bottle and sustainable Titripac® packaging for a reduced waste generationAccompanied with a detailed and batch-specific certificate of analysis (CoA) for an effective auditProduct label follows the ISO Guide 31 and contains information about ordering number, article description, lot number, safety data, and expiry date Packaging material subjected to comprehensive stability studies as per ISO Guide 35
