| Others are bipropellant, generally calling on monomethyl hydrazine as the fuel and nitrogen tetroxide as the oxidizer. |
| Osmium tetroxide was used as a secondary fixative and stain prior to a second wash in phosphate buffer. |
| The oxidizer used with hypergolic fuel is usually nitrogen tetroxide or nitric acid. |
| The cytoplasm of medullar cells, fixed in osmium tetroxide, stained more deeply with toluidine blue than that of cortical cells. |
| Electron microscopy was performed with fresh tissues fixed in glutaraldehyde and postfixed in osmium tetroxide. |
| The tissue is then placed for 8 to 10 days in a solution containing potassium chlorate, osmium tetroxide, formaldehyde, and glacial acetic acid. |
