词汇 | bunsen burner |
词源 | Bunsen burner; bunsenite. Robert Wilhelm Bunsen (1811– 99) invented the Bunsen burner that is standard equipment in every chemistry laboratory. This laboratory burner, which mix- es gas with air to produce a hot smokeless flame, wasn’t the only scientific contribution the German chemist made. He dis- covered, with Gustav Kirchhoff, the elements cesium and ru- bidium, and shared with Henry Roscoe the discovery of the reciprocity law, doing much original work in spectrum analy- sis. The Heidelberg professor also has bunsenite, a nickel mon- oxide, named in his honor. |
