Certipur® Secondary Reference Materials for Alkalimetry
Merck’s Certipur® product range of volumetric standards includes two secondary reference materials for alkalimetry: benzoic acid and potassium hydrogen phthalate. Both are very pure and stable solid standards perfectly suitable for your alkalimetry applications. These Certipur® volumetric standards are manufactured and extensively tested in compliance with the reagents parts of the European and U.S. Pharmacopoeias and measured with the highest possible precision by our DIN EN ISO/IEC 17025 accredited calibration lab. They are directly traceable to standard reference material from NIST as documented in the comprehensive, batch-specific Certificate of Analysis prepared for each product.
