Description
COD Standard ROTI®Calipure is a chemical oxygen demand calibration standard at 60000 mg O2/l in water, This aqueous reference material supports calibration and verification in COD determination methods used for water and environmental analysis. With a density of approximately 1 g/cm³ and a boiling point of 100 °C, the solution behaves like a typical aqueous standard under controlled laboratory conditions. Analytical chemists employ high-level COD standards to establish calibration curves, check instrument response, and confirm method performance across demanding measurement ranges. The ROTI®Calipure preparation from manufacturer Carl ROTH provides a defined oxygen-demand value expressed as milligrams of O2 per litre, supporting consistent analytical practice. Packaged in glass, is convenient for repeated sampling while protecting standard integrity. Laboratories performing wastewater, effluent, or process-water testing can incorporate this concentrate into quality-control routines. Clear labelling of the 60000 mg O2/l level facilitates planned dilution when lower working standards are required for routine photometric or titration-based COD assays in daily laboratory operation.

Questions about COD Standard, ROTI®Calipure 60000 mg O2/l in H2O, 100 ml, glass
What is this article?
COD Standard, ROTI®Calipure 60000 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.
