Description
Phenolphthalein paper roll is a continuous indicator paper format intended for qualitative laboratory and environmental testing routines. Each roll is 5 m long and 7 mm wide, giving a convenient strip width for spot checks, comparative observations and sequential sampling without the need to handle loose sheets. The product is supplied as a pack of five rolls, supporting steady consumption in teaching labs, quality-control benches and field kits where phenolphthalein paper is used regularly. Manufactured by Macherey-Nagel, the rolls fit the environmental analysis test-kit category and integrate easily with other indicator materials already in use. Compact outer dimensions and a net weight of 0,02 kg keep storage simple on crowded shelves or in mobile cases. Sections can be torn or cut as required, which helps limit waste during series of measurements. The roll presentation is practical for users who prefer a continuous supply rather than pre-cut pieces, and the defined length and width support consistent handling from one test to the next in professional technical environments.
This article is part of Indicators & indicator solutions, in Analytical standards & reference materials.

Questions about Phenolphthalein paper reel (5m reel)
What is this article?
Phenolphthalein paper reel (5m reel) is the article on this page. Luminix Health distributes Macherey-Nagel 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.
Which category should I open next?
