Ruthenium tetroxide aqueous 0.5% solution

Ruthenium tetroxide is very similar to Osmium tetroxide, and is used as a fixation/staining agent for electron microscopy. Ruthenium tetroxide offers excellent staining of saturated and unsaturated polymer materials as well as stabilising thin sections under the bombardment of the electron beam.In Crystal form: RuO4   F.W. 165.70   CAS #20427-56-96Melting point: 25.4°C Boiling point: 40°CNOTE: Penetration of ruthenium tetroxide into the tissue is poor.
