A calorimeter uses an insulated lid, or insulated surroundings. In the CAL2K the polystyrene surrounding is used as insulation to keep the heat of the liquid or solid sample during a reaction for an accurate measurement in the change of temperature to provide the best possible accurate results.
In an adiabatic oxygen bomb calorimeter the surrounding water jacket acts as the surrounding insulation, in combination with a heating element and stirrer to measure the change in temperature.
The CAL3K-AP uses surrounding ATC (Automatic Temperature Control) which is a special well with fast and precise temperature control. It has a very low mass and a low heating power. The ATC follows the vessel temperature so that the temperature losses are exactly the same as it was during the calibration. The ATC is more linear than the standard polystyrene insulation used in the CAL2K Calorimeter Range and applies to the CAL3K-AP Oxygen Bomb Calorimeter System.
The goal of insulating the bomb calorimeter system is to minimize the temperature loss from the system (calorimeter) to the surroundings (air) over time.
The Difference Between a Coffee Cup Calorimeter and a Bomb Calorimeter
A calorimeter is a device used to measure the quantity of energy transferred to its surroundings. Two of the most common types of calorimeters are the coffee cup calorimeter and the bomb calorimeter. They might use the same calorimetry principles, but are very different in design and operation.Learn More
The Structure and Function of Bomb Calorimeters
A calorimeter is a device, or machine, used for calorimetry. Calorimetry is the process of measuring the heat of a chemical reaction or the physical changes as well as the heat capacity. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber.Learn More
How does a bomb calorimeter work?
In short, the process of a calorimeter involves measuring the heat of a fuel sample when burned under stable temperature conditions to evaluate the heating energy of the fuel sample. The fuel sample can be a solid or liquid, but not a gas.Learn More
