Description
Crystal violet, C.I. 42535 and 42555 for microscopy is a classical staining dye supplied for microscopic work in a 25 g pack. Identified under CAS number 548-62-9, this material is intended for microscopy applications in microbiology and related laboratory staining procedures. The Colour Index designations C.I. 42535 and 42555 specify the dye identity used in standard microscopic staining protocols. Available from manufacturer Labbox in the LABKEM range, the 25 g quantity suits routine preparation of staining solutions for slide-based examination. With a net weight of 0,025 kg, the pack supports controlled dispensing in teaching, research and diagnostic microscopy settings. Crystal violet remains a widely recognised dye for morphological staining and differential techniques where violet colouration of cellular structures is required. This microscopy-grade presentation provides a straightforward solid dye format for laboratories that prepare their own staining baths and working solutions according to established protocols.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Crystal violet, C.I. 42535 and 42555 for microscopy, 25 g
What is this article?
Crystal violet, C.I. 42535 and 42555 for microscopy, 25 g is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Microscopy stains & staining solutions, inside Dyes, stains & indicators, in Lab chemicals.
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.
