Questions about Chromotrop®2 R, for microscopy, 10 g, glass
What is this article?
Chromotrop®2 R, for microscopy, 10 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dyes, stains & indicators, in Lab chemicals.
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.
Which category should I open next?
The category is Dyes, stains & indicators. The catalogue is Lab chemicals.
