Ready to use RuO4 solution is useful as a staining agent for electron microscopy of polymers, as well as a fixative for biological samples. Ruthenium tetroxide penetrates tissue very slowly, reacting strongly with proteins, glycogen and monosaccharides.
Ruthenium tetroxide in comparison to osmium tetroxide can be used in more aggressive form of staining for the study of polymers by TEM.
Supplied in pre-scored ampoules each with its own ampoule cracker.
Note: Occasionally, black rings may be seen at the top of the ampoules and are due to oxidation of the vapors when the ampoules are sealed. This does not have an effect on the material or end use of it.
Recommended Storage: 4°C in refrigerator
