Description
COD Standard ROTI®Calipure 20 mg O2/l in H2O is an aqueous chemical oxygen demand calibration standard intended for analytical laboratories that verify or calibrate COD measurement systems. The solution is prepared at a nominal level of 20 mg O2/l in water and is supplied in a 500 ml glass pack, giving ample volume for repeated calibration points, control charts, and instrument checks. Physical data list a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with a water-based matrix that integrates readily into routine wet-chemistry workflows. As part of the ROTI®Calipure line from manufacturer Carl ROTH, this standard supports quality assurance in environmental, wastewater, and process laboratories where reliable COD reference values are required. The glass bottle format helps maintain sample integrity during storage and dispensing, while the defined 20 mg O2/l concentration enables straightforward preparation of working checks at the lower end of many COD working ranges. Analysts can use the material within established calibration protocols for photometric or titrimetric COD methods without altering the stated composition. Clear unit and physical specifications facilitate inventory control and method documentation in regulated or accredited testing environments.

Questions about COD Standard, ROTI®Calipure 20 mg O2/l in H2O, 500 ml, glass
What is this article?
COD Standard, ROTI®Calipure 20 mg O2/l in H2O, 500 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reagents for analysis (Ph. Eur., ASTM, DIN), inside Analytical standards & reference materials, in Lab chemicals.
A reagent for analysis is a chemical whose impurities are limited so they do not become a signal in a titration, a digestion or a photometric method. Pharmacopoeia, ASTM and DIN names point at different limit lists. The grade, not only the identity, is the purchase.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
