Certipur® Volumetric Standards for Acidimetry
Certipur® Secondary Reference Materials
|
Merck’s Certipur® product range of volumetric standards includes two secondary reference materials for acidimetry: sodium carbonate and Tris(hydroxymethyl)aminomethane. Both are very pure and stable solid standards perfectly suitable for your acidimetry applications.
These Certipur® volumetric standards are manufactured and extensively tested in compliance with the reagents parts of the European and/or 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.
