5645 T Mahler's Bomb Calorimeter, for determining the calorific values of solids, liquids, and 

 gases. The apparatus consists of 



Insulated outer vessel. 



Combustion bomb of steel, enamelled inside. 



Platinum capsule. 



Platinum electrodes. 



Iron wire for ignition. 



Stirring arrangement. 



Battery. 



Set of thermometers : 8 to 19 C. in ^, 18 to 20 C. in -^, 14 to 25 C. 



40 ft. cylinder of oxygen, with pressure gauge and connections to bomb. 



The combustion takes place in a closed bomb or cylinder of steel. The substance, if solid, is placed on a 

 small platinum capsule, and the bomb is filled with oxygen at 25 atmospheres' pressure. Ignition is produced 

 by passing an electric current through an iron wire lying in contact with the substance. The bomb is nickel- 

 plated outside, and is lined inside with enamel to resist the corrosive action of the nitric acid formed during 

 the combustion. The distinguishing feature of Mahler's bomb is this layer of enamel, which replaces the more 

 expensive platinum lining of Berthelot's apparatus.
