Certipur® Secondary Reference Materials in Volumetry

Proper titer determination is an important prerequisite for accurate and comparable analysis in the titration laboratory. Titration results are influenced by the volumetric solution itself, the measuring temperature, the equipment and the handling. Merck’s Certipur® secondary reference materials for volumetry are the perfect choice for reliable titer determination in order to standardize volumetric solutions.and processes.

Our Certipur® product range for volumetric standards comprises high-purity secondary reference materials for acidimetry, alkalimetry, argentometry, complexometry, iodometry, and redox titration. They are manufactured and extensively tested in compliance with the reagents parts of Pharmacopoeias and measured with the highest possible precision by our ISO/IEC 17025 accredited calibration lab. All Certipur® volumetric standards are directly traceable to standard reference material from NIST (National Institute of Standards & Technology, Gaithersburg, USA). A comprehensive, batch-specific Certificate of Analysis prepared for each product.
