说明

一般說明

Malachite green Oxalate (C.I. 42000) is a dry dye that is used for the preparation of a staining solution that can be used for a spore staining according to Rakette. It is possible to use Malachite green dye for differential spore staining in bacteriological samples of human origin, Dye is used in a hot staining method to stain specifically spores. Counterstain with a red dye for better visualization. The dye has a constant dye content and a reliable high quality and thus, is registered and certified as IVD & CE product, one of the major precondition for a reproducible diagnostic staining.
