Beschreibung

Allgemeine Beschreibung

Erythrosin B (C.I. 45430)for microscopy Certistain^®, is a dry dye for microscopy that is often used as a counterstain, vizualising proteins, connective tissues, fibers and keratin in sample material of human origin. Depending on user requirements and personal preferences, it can be used for the preparation of the commonly used aqueous or alcoholic Erythrosin B staining solutions. As the dye belongs to the portfolio of Certistain^® dyes, it is chemically analyzed according to strict specifications before release (CE marked and IVD product) and a high staining quality, with reliable staining results is guaranteed. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
