General description

The dry dye Orange G (C.I. 16230) for microscopy Certistain^®, is used for the preparation of a staining solution for Papanicolaou’s staining in cytology in material of human origin. The effect of the Orange G staining solution is considerable in smears with keratinized cells under acidic pH conditions, when the obvious orangeophilic cytoplasmic stain is recognizable. As a CERTISTAIN^® dye it is chemically quality-certified according to highest standards and strict specifications.
