Description
Prepared COD vials (LR) 0–150 mg/l are ready-to-use reagent vials for chemical oxygen demand determination in water and wastewater analysis. Each vial measures Ø 16 mm × h 100 mm and contains 3,3 ml of pre-dosed reagents, of which 2,4 ml is sulfuric acid, supporting photometric COD measurement in the low range without manual reagent preparation. The pack provides 25 vials for routine laboratory use. Mercury-free vials from manufacturer Labbox offer a safer choice from environmental and occupational-health standpoints; they do not deliver the same precision and reliability as mercury-based methods, and many supervisory authorities expressly require mercury sulfate for compliance testing to eliminate chloride interference. The vials work with the PrimeLab 1.0 Multitest WATER-ID photometer and with photometers from LOVIBOND, WTW, MACHEREY-NAGEL, MERCK, HANNA, AQUALYTIC, PALIN, BIOCHROM, HACH and other manufacturers that accept 16 mm vials. Pre-filled format simplifies digestion and measurement steps, reduces preparation effort and supports consistent sample handling in industrial, municipal and environmental water-quality testing programmes.

Questions about COD (LR) 0 - 150 mg/l prepared vials, 25 pcs
What is this article?
COD (LR) 0 - 150 mg/l prepared vials, 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?
