Description
Gram's decolourising solution is a ready-to-use reagent for microscopy, formulated specifically for the decolourisation step in the classic Gram staining method. Packaged in a 500 ml glass bottle, it enables selective removal of the primary crystal-violet complex from Gram-negative bacteria while leaving Gram-positive cells stained. Key physical parameters include a density of 0,8 g/cm³, a flash point of 12 °C and a boiling point of 78 °C; the product carries UN number 1993. Offered by manufacturer Carl ROTH, this solution integrates smoothly into manual or semi-automated Gram workflows in clinical microbiology and teaching laboratories. Ready-to-use presentation reduces preparation time and helps standardise the critical differentiation step that distinguishes Gram-positive from Gram-negative organisms. Suitable for diagnostic bacteriology, quality-control microscopy and educational practicals requiring a consistent decolouriser in a practical laboratory pack size.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Gram's decolourising solution, for microscopy, ready-to-use, 500 ml, glass
What is this article?
Gram's decolourising solution, for microscopy, ready-to-use, 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 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.
Which category should I open next?

Shelves beside this one are Fluorescent dyes & labels and Dyes & pigments.
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.
