Description: | none MANU Peter Stevenson. circa 1850 9, Lothian Road, Edinburgh, Midlothian, Scotland DES after DAVY, Humphry,Sir 1816 The Royal Institution, Albermarle Street, London, England One of two objects miscatalogued as one item. The gauze in this flame arrester works in exactly the same way as in a Davy lamp. The gauze acts as a difuser that allows gases or vapours of the solvent in the flask to pass through it in this way the vapours and gauze absorb the heat produced by any flame above them thus preventing the flame from passing through the gauze. This arrester has an additional but unneccessary saftey feature consisting of a brass flap that is drawn up by the drop in pressure caused by the combustion above the gauze cutting off the supply of vapours or gases. It would of course prevented liquids and gases escaping if the container was inverted but would allow liquids to be poured in to the container. | 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: | HISTORICAL COLLECTION : SCIENTIFIC INSTRUMENT : HISTSCI : | 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 |
