Description
Prepared COD vials (LR) 0 - 150 mg/l are mercury-free, reagent-filled tubes for photometric determination of chemical oxygen demand in the low range. Each vial measures Ø 16 mm × 100 mm and contains 3,3 ml of reagents, of which 2,4 ml is sulfuric acid (CAS 7664-93-9). Ready-to-use dosing simplifies CSB/COD workflows and reduces preparation steps at the bench. The vials are compatible with the PrimeLab 1.0 Multitest WATER-ID photometer as well as LOVIBOND, WTW, MACHEREY-NAGEL, MERCK, HANNA, AQUALYTIC, PALIN, BIOCHROM, HACH and other systems that accept 16 mm vials. Offered in packs of 25 pieces from manufacturer Labbox, the mercury-free approach is preferable from an environmental and health perspective. It does not match the precision and reliability of mercury-based methods, and many supervisory authorities still require mercuric sulfate to remove chloride interference during conformity testing. Well suited to low-range COD monitoring of cleaner waters and process streams in laboratory practice.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about COD (LR) 0 - 150 mg/l prepared vials, mercury-free, 25 pcs
What is this article?
COD (LR) 0 - 150 mg/l prepared vials, mercury-free, 25 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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.
Which category should I open next?
