Description Notes

Rosenhain fuel calorimeter consisting of three parts: an outer wooden case with openings in the side, the calorimeter vessel, and the combustion chamber. The calorimeter vessel is made of metal with two large glass windows. The combustion chamber is formed of glass lamp chimney closed at the top and bottom by nickel-plated brass clasping plates with rubber washers. The plates are held together by three metal uprights fixed to the upper plate through which a tube passes carrying the electric ignition device. The upper late also carries a tube with a tap and a wire gauge nozzle for admitting oxygen into the vessel. There is an aperture in the upper plate which is closed by a ball valve. In the bottom of the combustion chamber is a metal container holding a small silica dish (broken). There is a thermometer support on one of the uprights and supporting ring.
