Description
COD Standard 500 ppm, 500 ml is a chemical oxygen demand reference solution supplied at a concentration of 500 ppm in a 500 ml pack. Offered as 1 pc, it provides a defined standard for calibration, verification, or quality-control checks in COD photometric and related spectroscopic workflows. Net weight is 0,57 kg and gross weight is 1,57 kg, keeping the bottle practical for laboratory handling and storage. This COD standard from manufacturer Hanna Instruments is produced in Romania and sits within the spectroscopy accessories range used for water and wastewater analysis. Laboratories that run chemical oxygen demand methods can use the 500 ppm level to support instrument checks and method consistency across analytical batches. The liquid format allows straightforward dosing into cuvettes or preparation vessels according to the laboratory’s established COD procedure. Clear concentration labelling at 500 ppm helps operators select the correct standard for the intended measuring range. The product is suited to environmental, industrial, and municipal laboratories that maintain COD photometry as part of routine monitoring programmes.

Questions about COD standard 500 ppm, 500 mL, regular bottle
What is this article?
COD standard 500 ppm, 500 mL, regular bottle is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in Lamps, cuvette holders & accessories, inside Spectroscopy & photometry, in Lab instruments.
A spectrophotometer's lamp, deuterium for UV and tungsten for visible, is a consumable with a life in hours. A cuvette holder sets the path. A 10 mm holder does not correctly read a 1 mm cell unless the software is told. The accessory has to fit that optical bench.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
