A small laboratory burner consisting of a vertical metal tube connected to a gas source and producing a very hot flame from a mixture of gas and air let in through adjustable holes at the base. a piece of equipment that produces a hot gas flame, for scientific experiments
A zinc-carbon cell in which the zinc (amalgamated) is surrounded by dilute sulphuric acid, and the carbon by nitric acid or a chromic acid mixture, the two plates being separated by a porous cup
born March 31, 1811, Göttingen, Westphalia died Aug. 16, 1899, Heidelberg, Baden German chemist. With Gustav Robert Kirchhoff, he observed ( 1859) that each element emits light of a characteristic wavelength, opening the field of spectrochemical analysis. They discovered several new elements (including helium, cesium, and rubidium) by spectroscopy. His only book discussed methods of measuring volumes of gases. He invented the carbon-zinc battery, grease-spot photometer (see photometry), filter pump, ice calorimeter, and vapour calorimeter. Though often credited with inventing the Bunsen burner, he seems to have made only a minor contribution to its development
