General description

Gram-Color - stain set for the Gram staining method, is used for human-medical cell diagnosis and serves the purpose of the bacteriological investigation of sample material of human origin, for example smears of body fluids. The Gram-Color solutions are modified and designed in such a way that staining can be carried out in staining cells, on the staining rack, and also in automated staining systems. Gram-color modified, phenol-free is a staining set for staining microorganisms. Aniline dyes in the cell tissue of microorganisms form a red dye-iodine complex when exposed to iodine. Sodium hydrogen carbonate enhances the formation of this complex further still. In gram-positive microorganisms the dye-iodine complex cannot be subsequently dissolved from the cells by decolorizing agents such as alcohol or acetone. The cell remains dark blue in color. In gram-negative microorganisms the dye-iodine complex is dissolved and the cell turns red as a result of counterstaining with fuchsin. Gram-color modified, phenol-free is an IVD / CE product.
The package is sufficient for 250 applications. For further information, please see the IFU which can be found in the kit.
