Description
COD Standard ROTI®Calipure 5000 mg O2/l in H2O is an aqueous calibration standard intended for chemical oxygen demand (COD) work at elevated reference levels. The 5000 mg O2/l concentration suits calibration points, span checks and quality-control samples where higher oxygen-demand values are required. Density is approximately 1 g/cm³ and the boiling point is 100 °C, reflecting the aqueous formulation. Environmental, municipal and industrial laboratories use such COD standards to align photometers, titrators or kit-based systems with a known oxygen-demand value expressed in milligrams per litre. This ROTI®Calipure grade from manufacturer Carl ROTH supports analytical chemical workflows focused on water and wastewater characterisation. The clearly marked 5000 mg O2/l level helps operators choose the correct standard among a concentration series. As part of dedicated COD Standards within calibration reagents, it integrates into established method protocols without on-site preparation of the stock reference.

Questions about COD Standard, ROTI®Calipure 5000 mg O2/l in H2O, 100 ml, glass
What is this article?
COD Standard, ROTI®Calipure 5000 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.
