Ruthenium(IV) oxide 0.5% in aqueous solution stabilized
Ruthenium (IV) oxide
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 stabilizing thin sections under the bombardment of the electron beam. Penetration of ruthenium tetroxide into the tissue is poor.
