A Geissler tube is a precursor to modern gas discharge tubes, demonstrating the principles of electrical glow discharge, akin to contemporary neon lights, and central to the discovery of the electron. [ 1 ]: 67 This device was developed in 1857 by Heinrich Geissler, a German physicist and glassblower. A Geissler tube is composed of a sealed ...
Geissler tubes are sometimes still used in physics education to demonstrate the principles of gas discharge tubes. Influence. Geissler tubes were the first gas discharge tubes, and have had a large impact on the development of many instruments and devices which depend on electric discharge through gases.

Introducing luorescent substances in Geissler tubes extremely bright efets can be obtained6. Some of these tubes are represented in [Fig. 4]. Using the new Geissler pump, Julius Plücker (1801-1868) could improve his experiments, having observed that the walls of the glass tube emitted a phosphorescent light in the region of the cathode.

The other Geissler tubes have lost their vacuum and were filled with colored water for show purposes. Hook an induction coil to the two tubes at the electrodes. Turn on the coil and adjust the power. The liquids in the tubes are fluorescent and will give some interesting colors. The new set of small Geissler tubes will work with either the ...
The tube was invented by the German physicist and glass-blower Heinrich Geissler in 1857. The Geissler tube was an evacuated glass cylinder with an electrode at each end, it would contain one or more of the following rarefied (thinned) gasses, such as neon, argon, or air, mercury or other conductive liquids, or ionizable minerals or metals, such as sodium.

The Geissler Tube is a sealed glass cylinder of a unique design with a metal electrode at each end. The Geissler Tube was invented by the German glassblower and physicist, Johann Heinrich Wilhelm Geissler (1814-1879) in 1857. Geissler tubes were the first gas discharge tubes. Each contains rarefied gasses such as neon or argon; conductive fluids; or ionizable minerals or metals. When voltage is...
