Description
Indigo carmine, C.I. 73015 USP, NF is a laboratory dye preparation offered in a convenient 25 g pack for use in microbiological media work and related analytical routines. Listed under Colour Index 73015 and designated USP, NF in the product name, it supports staining, indicator and media-preparation tasks where a defined indigo carmine grade is required. The material belongs to the LABKEM product line and is intended for controlled laboratory handling rather than bulk industrial dyeing. Net weight of the unit is 0,026 kg, matching the compact 25 g fill for bench-scale consumption and inventory planning. Supplied from manufacturer Labbox, the dye fits standard microbiology and media workflows in research, quality-control and teaching laboratories. Clear labelling of the C.I. number and USP, NF designation helps users align the reagent with protocol specifications and documentation. The single 25 g pack size suits occasional to moderate use without excess stock. Suitable for laboratories that need a readily identifiable indigo carmine grade for media and indicator applications.

Questions about Indigo carmine, C.I. 73015 USP, NF 25 g
What is this article?
Indigo carmine, C.I. 73015 USP, NF 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.
