Used to stain blood, bone marrow smears, and clinical cytological specimens.


The dry mixture of the Leishman's eosin methylene blue dye is used for the self-preparation of the Leishman's staining solution. The staining method according to Leishman is one of the standard techniques in hematological diagnostic procedures. Like Wright's eosin methylene blue and May-Grünwald's eosin methylene blue, it is used for staining of blood and bone marrow smears and clinical cytological specimens. The dye is chemically quality-certified according to highest standards and strict specifications. As an IVD product and CE registered, it can be used hassle-free in diagnostics and laboratory accreditations.
