Description: | Solid fuel calorimeter; in three parts; 2 metal cylinders that sit within one another; outer can and inner can to protect against heat loss; inner section is a sample chamber that screw into the inner can; specimen was ignited within the chamber; chamber is engraved 'Germany' and Rein? Crel? and with an unclear symbol (stamp is unclear); has cork protruding through the wooden lid which would hold a themometer; two other terminals on the top and ivory makers label; described as Roland Wild's Solid Fuel Calorimeter; no 413 punched on top. In brief, a mixture of the fuel and sodium peroxide is fired in the combustion chamber immersed in water. The rise in temperature of the water is a measure of the heat given off. The whole is within a double-walled, polished (nickel-plated?) chamber that prevents radiation and conduction between the inside and the outside. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1890-1950 | Source: | University of Aberdeen | Creator: | Alex.
