Description
COD Standard ROTI®Calipure 50 mg O2/l in H2O is an aqueous calibration standard for chemical oxygen demand determination, prepared at 50 mg O2/l in water. The preparation shows a density of about 1 g/cm³ and a boiling point of 100 °C, reflecting its water-based matrix and supporting familiar handling in analytical chemistry suites. Offered within the ROTI®Calipure range from manufacturer Carl ROTH, the standard addresses routine needs in environmental monitoring, wastewater laboratories, and industrial process control where COD values must be traced to defined reference solutions. The compact limits excess volume while still providing enough material for multiple calibration runs or proficiency checks. Users can incorporate the 50 mg O2/l level directly into multi-point calibration curves or as an independent check standard alongside other COD concentrations. Documented physical properties and unit size simplify registration in laboratory information systems and support consistent application across photometric and classical COD procedures.

Questions about COD Standard, ROTI®Calipure 50 mg O2/l in H2O, 100 ml, glass
What is this article?
COD Standard, ROTI®Calipure 50 mg O2/l in H2O, 100 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.
