Calorimeter Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-11653
Jlab Export is a leading Calorimeter Manufacturer,and suppliers in India
Calorimeter (code EL-CL-11653) is a copper calorimeter, model JL 185/40, in which a polished inner vessel of 5.1 cm diameter sits inside an electroplated copper outer vessel, closed by a fitted Bakelite lid with a rubber stopper and a metal stirrer. Students use it for heat-exchange work such as finding specific heat or heat of neutralisation. JLab builds this calorimeter in Ambala, India.

How the Two Vessels Keep the Heat In
The air gap between the inner and outer vessels slows the loss of heat to the room, and the lid stops warm air escaping from the top. Copper conducts heat well, so the inner vessel quickly settles at the same temperature as the liquid in it; its mass and the specific heat of copper are then included in the heat balance.
Taking a Reading
Weigh the empty inner vessel with the stirrer before the experiment. Pass a thermometer through the rubber stopper so the bulb sits in the liquid without touching the base, stir gently and steadily, and note the temperature at fixed intervals. Dry the copper after use so the polished surface keeps its shine, which helps it lose less heat by radiation.
