Certipur® Secondary Reference Materials for Complexometry


Merck’s Certipur® product range of volumetric standards includes two secondary reference materials for complexometry: zinc and calcium carbonate. Both are very pure and stable solid substances perfectly suitable for your complexometry applications. These Certipur® volumetric standards are manufactured and extensively tested in compliance with the reagents parts of the U.S. Pharmacopoeia and measured with the highest possible precision by our DIN EN ISO/IEC 17025 accredited calibration lab. They are directly traceable to standard reference materials from NIST as documented in the comprehensive, batch-specific Certificate of Analysis prepared for each product.
