Description: | none. MANU Unsigned. circa 1920 DES after GEISSLER,Johann,Heinrich,Wilhelm. 1855 Bonn, Germany. This is a small Geissler tube in the form of a fine pipe which is bent in a single kink. The tube is surrounded by a sealed water filled jacket that contains a pink water soluble fluorescent dye, which fluoresces a suffused white. The lead in wires are a composite, having the normal platinum glass seal with a short piece of carbon attaching this to the aluminium electrodes. N.B. all gas discharge tubes emit X-rays this is because the electrons from the cathode strike the atoms of gas in the tube at high energy levels. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
