Description
Eosin Y solution 1 % in water is a ready-to-use aqueous staining reagent formulated for microscopy. Identified by CAS number 17372-87-1 and EG number 241-409-6, the preparation has a density of 1 g/cm³ and a boiling point of 100 °C, consistent with a water-based dye solution. It is Laboratories use this concentration for routine bright-field microscopy and related staining protocols that require a defined aqueous eosin Y bath. The solution comes from manufacturer Carl ROTH and supports reproducible sample preparation in pathology, histology, and teaching laboratories. Clear labelling of concentration and solvent helps standardise staining steps and reduces the need for in-house dilution of solid dye.
This article belongs on Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Eosin Y solution 1 % in water, for microscopy, 500 ml, glass
What is this article?
Eosin Y solution 1 % in water, for microscopy, 500 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Microscopy stains & staining solutions, inside Dyes, stains & indicators, in Produits chimiques de laboratoire et industriels.
A microscopy stain binds a structure so it can be seen: haematoxylin on nuclei, eosin on cytoplasm, Gram reagents on a bacterial wall. A ready solution and a dry dye to be dissolved are different articles. The method names the stain. A substitute dye is a different method.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
