Description
Thymolphthalein indicator solution is a ready-to-use pH indicator preparation at 0,1 % in denatured ethanol, supplied in a 500 ml glass bottle for titration and analytical work. The solution exhibits a density of 0,79 g/cm³, a flash point of 13 °C and a boiling point of 78 °C, reflecting its ethanolic matrix and requiring standard flammable-liquid handling in the laboratory. Formulated for indicators used in titration, it supports clear end-point recognition in acid–base determinations and related pH-dependent colour-change applications. This product from manufacturer Carl ROTH is intended for laboratories that prefer pre-dissolved indicator solutions rather than preparing stock from solid dye. The glass packaging protects the ethanolic content during storage and dispensing at the bench. Typical uses include classical volumetric analysis, teaching laboratories and quality-control titrations where a thymolphthalein colour transition is specified. With a pack weight of 0,800 kg and classification under ready-to-use pH indicator solutions, the 500 ml unit is practical for shared reagent stations. Observe usual precautions for UN 1170 ethanolic preparations when transferring or storing the solution.

Questions about Thymolphthalein indicator solution, 0,1 % in ethanol denatured, 500 ml, glass
What is this article?
Thymolphthalein indicator solution, 0,1 % in ethanol denatured, 500 ml, glass is the article on this page. Luminix Health distributes Carl Roth 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.

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
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.
