Description
AQUADUR 4-21 is a water-hardness test-strip system for rapid semi-quantitative assessment of total hardness in water samples. Colour steps are graded at 4 >7 >14 >21 degrees German hardness (°dH), enabling clear classification across soft to moderately hard ranges typical of environmental and process waters. Every strip is individually sealed in a printed pouch, protecting the reagent zones until the moment of use and simplifying handling in busy laboratories or field kits. The pack comprises 1000 sealed strips, supporting high sample throughput in monitoring programmes, service work and routine quality checks. Dip-and-read evaluation does not require elaborate instrumentation, so the strips are suitable for both on-site screening and laboratory bench use. AQUADUR 4-21 from manufacturer Macherey-Nagel belongs to the established range of environmental-analytics test kits focused on straightforward hardness determination. The sealed presentation helps preserve strip performance during storage and distribution, while the printed sealing aids identification and traceability within the pack of one thousand pieces.

Questions about AQUADUR 4-21, single sealed, 1000 pcs
What is this article?
AQUADUR 4-21, single sealed, 1000 pcs is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Substances de référence & réactifs (autres), inside Étalons analytiques & matériaux de référence, in Produits chimiques.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
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.
