Description
Methylene blue solution is a staining reagent prepared for microscopy, including Gram staining and related histological work. The formulation is supplied in a 500 ml glass bottle and shows a density of approximately 1 g/cm³ together with a boiling point of 100 °C, properties that support routine bench handling in life-science laboratories. This preparation from manufacturer Carl ROTH is intended for consistent dye performance during microscopic examination of specimens in research, teaching, and diagnostic staining workflows. Its aqueous character fits common differential staining sequences used in histology and microbiology without requiring complex on-site reconstitution. At a unit weight of 0,785 kg, the pack size suits regular laboratory consumption for slide preparation and protocol development. Categories linked to the product cover life science, histology and microscopy, staining, and Gram staining, underscoring its role in classical and contemporary staining techniques. Laboratories can place the solution directly into established microscopy protocols where a reliable methylene blue dye is required for contrast and structural visualisation.
This article is part of Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about Methylene blue solution
What is this article?
Methylene blue solution 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?
The category is Dyes, stains & indicators. The sub-category is Microscopy stains & staining solutions. The catalogue is Lab chemicals.
