Polysciences/Ruthenium Tetroxide, 0.5% stabilized aqueous sol | Polysciences, Inc./25x10 ml ampoules/18253-25
Ready to use RuO4solution 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 tip of the ampoules and are due to oxidation of the vapors during sealing process of ampoules. The black ring present on tip of glass ampoule has no effect on the actual material or end use as confirmed by our 96 hour in-house material testing performed.
