General description

The staining method according to May-Grünwald is one of the standard techniques in hematological diagnostic procedures. Like Wright′s eosin methylene blue solution and Leishman′s eosin methylene blue solution, this ready-to-use solution is used for staining of blood and bone marrow smears and clinical cytological specimens. The 500 ml bottle provides ca. 1500 stainings. The May-Grünwald′s eosin methylene blue solution is an IVD / CE registered / certified product and the 500 ml bottle is sufficient for staining up to 1600 slides in Hellendahl cells. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
