Use of the Adiabatic Calorimeter Indonesia in the Laboratory

Heat is one of many parameters measured in the calorimetry lab; or any laboratory in this case. One of the instruments used in the measurement of heat in this laboratory is the adiabatic calorimeter.

During chemical reactions, the reactants are converted into products. If the reaction requires heat to create these products, the reaction is called endothermic. Heat flows into the system, causing reactants to turn into products. If the reaction creates heat it is considered an exothermic reaction. It is often desirable to determine the magnitude and direction of heat flow for certain reactions.

The process used to measure heat flow is called calorimetry - this is the science of measuring heat of chemical reactions or physical changes and heat capacity and is the focus of work done in the calorimetry lab.

Differential calorimeter scanners, isothermal microcalorimeters, accelerated calorimeter titrations and calorimeters are some of the commonly used calorimeters. A simple calorimeter consists of a thermometer attached to a metal container full of water and suspended above the combustion calorimeter indonesiachamber. Measuring the heat flow in a reaction requires a closed system, namely the calorimeter or depending on the application, an adiabatic calorimeter.

This type of calorimeter is used to check uncontrolled reactions. In most systems without special precautions, the system not only exchanges enthalpy with its environment, but also changes temperature. To prevent this complication, thermochemistry uses an instrument that is well insulated in the calorimetry lab, keeping the transfer of energy (and enthalpy) as heat across the boundary between the calorimeter and its surroundings effectively zero during the experiment.

Because the calorimeter runs in an adiabatic environment, every heat generated by the sample being tested causes an increase in temperature, which then triggers a reaction. The adiabatic calorimeter is never completely adiabatic, because some of the sample heat will always be lost to the sample holder.

Ultra-sensitive calorimetry is an important technique for molecular level research and product testing. This plays a role in the analysis and development of pharmaceutical and polymer products in modern calorimetry labs. Although it saves researchers, chemists, and engineers a large amount of time and money, maybe this is one of the best product development secrets.
