General description
Light green SF yellowish (C.I. 42095) for microscopy Certistain®, is a dry dye that is used for the preparation of a staining solution which is is widely used as a counterstain. for e.g. trichrome Masson-Goldner staining in histological sections or for Papanicolaou’s polychromatic staining in cytology of samples human origin. As CERTISTAIN® dye it is chemically quality-certified according to highest standards and strict specifications.
