詳細

詳細

Methylene blue (C.I. 52015) for microscopy Certistain^® is a dry dye that is used in bacteriology for an overview stain and as counterstaining for Ziehl-Neelsen method in sample material of human origin. Bacteria appear blue. The dye has a further important application in hematology: Methylene blue and eosin are the main components of many staining solutions and dye mixtures. Certistain^® is the product group for seleceted high quality dyes that fulfill all quality requirements of IVD and CE registration. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
