Description
Total Hardness 1 and 2 liquid reagents (20/10 ml) are photometric-grade reagents formulated for reliable determination of total water hardness in environmental and pool water analysis. Supplied as a matched liquid pair, they support standardised photometry workflows and are intended for use with photometric methods and the PoolLab 2.0 photometer. Each pack contains 30 pc(s) of the liquid reagents, offering a practical laboratory format for routine hardness testing. The reagents are produced to photometer quality for consistent colour development and measurement readiness in WATER ID applications. From manufacturer Labbox, this liquid reagent set fits water-testing kits used in environmental analytics where total hardness parameters must be tracked with photometric precision. Net weight is 0,025 kg per pack. Suitable for laboratories and field setups that rely on liquid reagents rather than tablets or powders, the product supports clear, method-oriented hardness 1 and 2 measurements without unnecessary complexity in sample preparation.

Questions about 20/10 ml total hardness 1 and 2 (liquid)
What is this article?
20/10 ml total hardness 1 and 2 (liquid) is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, 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.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Produits chimiques.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
