Calibration Standards

Calcium Carbonate, Chelometric Standard, Powder, ACS - A Primary Standard manufactured by Spectrum is an analytical reagent of exceptional purity and is specially manufactured for standardizing volumetric solutions and preparing reference standards . As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
