Description
Phenol red RAPID and DPD No. 1 (Cl2 / Br2) RAPID tablets are fast-dissolving reagent tablets for use with a PoolTester in rapid semi-quantitative pool and bathing-water checks. Phenol red supports pH colour comparison, while DPD No. 1 RAPID tablets address free chlorine and bromine. The RAPID format is intended for quick dissolution during routine field or bench testing. This pack supplies tablets for 30 tests of each type and is matched to PoolTester workflows that use a test block with eight pH scale values (measuring range 6,8 – 8,2) and sixteen chlorine and bromine scale values (DPD No. 1 free Cl2: 0,1 – 6,0; Br2: 0,22 – 13,2). Offered by manufacturer Labbox in the WATER ID line, the tablets suit environmental analytics, pool service and laboratory quality control where simple visual readout is required. Net weight is 0,200 kg. They serve as dedicated consumables for combined pH, chlorine and bromine measurement without extra instrumentation beyond the comparator block and colour scales, supporting consistent day-to-day water testing.

Questions about Tablets phenol Red RAPID / DPD Nº1 (free Cl2 / Br2) RAPID for PoolTester, 30 pcs
What is this article?
Tablets phenol Red RAPID / DPD Nº1 (free Cl2 / Br2) RAPID for PoolTester, 30 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Indicators & indicator solutions, inside Analytical standards & reference materials, in Lab chemicals.
An indicator solution changes colour at a stated point, usually a pH interval or a redox potential, so a titration endpoint can be seen. The solvent and the concentration decide how sharp the change is. A solid indicator dye and a ready solution are different articles.
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.
