          DescriptionTRYPAN BLUE (C.I. 23850) FOR MICROSCOPY
          OverviewTrypan blue (C.I. 23850) is a dry dye for the preparation of a color staining solution, staining histological sample material of human origin, e.g. trichrome staining in collagenous connective tissue.
          The dye is a CE certified IVD product and has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.
