Opis

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. As an IVD product and CE registered, it can be used hassle-free in diagnostics and laboratory accreditations. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
