Beschreibung
CSB 09773 Hg-free is a mercury-free chemical oxygen demand (COD) reaction cuvette test for quantitative determination of COD in water and wastewater samples. The measuring range is 100 to 1500 mg/l COD, with a defined sample volume of 2 ml. Each pack supplies 25 ready-to-use 16 mm round cuvettes and applies chromosulfuric acid oxidation as the analytical method. Results correspond to DIN ISO 15705, EPA 410.4, APHA 5220 D and ASTM D1252-06 B, supporting standardised laboratory practice. The cuvettes are intended for use with PhotoLab® and pHotoFlex® photometers. From manufacturer WTW - a Xylem brand, the kit includes Combicheck CC20 compatibility and a batch certificate for traceability. The mercury-free formulation offers laboratories a practical route to COD measurement without mercury-containing reagents, suited to routine organic-load monitoring, process control and environmental analysis. Fixed cuvette geometry and a clear sample volume help integrate the test into established photometric workflows for aqueous matrices in analytical and quality-control laboratories.
This article is part of Cuvette tests (Nanocolor), in Test kits & water analysis.

Questions about COD 09773 Hg-free, COD Chemical Oxygen Demand (mercury-free) Reaction
What is this article?
COD 09773 Hg-free, COD Chemical Oxygen Demand (mercury-free) Reaction is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in Cuvette tests (Nanocolor), inside Test kits & water analysis, in Labor- und Industriechemikalien.
A cuvette test is a ready optical cell containing the reagents for one water or one chemical determination. The sample is added, the cell goes into a photometer, and the range printed on the box is the range of the answer. It is a method, packaged, not a bottle of reagent to assemble.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
