What is Calorimeter?
A calorimeter is an insulated device used to measure the heat released or absorbed during a chemical reaction, physical change, or combustion. Common types include the coffee-cup calorimeter (constant pressure) for solution reactions and the bomb calorimeter (constant volume) for combustion reactions. Calorimetry data is used to determine enthalpy changes.

A calorimeter is an insulated device used to measure the heat released or absorbed during a chemical reaction, physical change, or combustion. Common types include the coffee-cup calorimeter (constant pressure) for solution reactions and the bomb calorimeter (constant volume) for combustion reactions. Calorimetry data is used to determine enthalpy changes.
Calorimeters measure heats of reaction, solution, fusion, combustion, and adsorption. They are essential in thermochemistry, pharmaceutical formulation (DSC calorimetry), materials characterisation, food science, and industrial process safety assessments.
Bomb calorimeters operate under high oxygen pressure and present explosion hazards if overloaded or improperly sealed. Isothermal titration calorimeters (ITC) are low-hazard. Always calibrate calorimeters before use and follow protocols for the specific model.
