Description
Light green SF (C.I. 42095) is a microscopy dye used in biological staining applications in histology and related laboratory workflows. It is identified by CAS number 5141-20-8 and EG nr. 225-906-5, with empirical formula C₃₇H₃₄N₂Na₂O₉S₃ and a molar mass of 792,86 g/mol. Specified for microscopy, the dye supports colour contrast in tissue and cellular preparations where green counterstaining is required. The product is As a member of the dyes and pigments range for biological applications, it fits established microscopy protocols and teaching or research settings. Material from manufacturer Carl ROTH provides clear catalogue identity for purchasing and documentation. Defined molecular data assist formulation calculations and method transfer between laboratories. The glass presentation is suited to storage and handling of solid dyes in controlled laboratory environments focused on reproducible microscopic staining results.

Questions about Light green SF (C.I. 42095), for microscopy, 5 g, glass
What is this article?
Light green SF (C.I. 42095), for microscopy, 5 g, 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?
The category is Dyes, stains & indicators. The sub-category is Microscopy stains & staining solutions. The catalogue is Lab chemicals.
