Differential Scanning Calorimeters

A differential scanning calorimeter is a thermal analysis instrument. It is mainly used in materials science, chemistry, biology, drug development, food industry, and energy fields. Differential scanning calorimeters can also be used to measure the melting point, boiling point, and other properties of solid and liquid materials.

1. Inorganic substances: such as metals, minerals, and ceramics.
2. Organic compounds: including various organic materials and polymers.
3. Drugs: used for thermal analysis of drugs, such as reaction heat, transition heat, etc.
4. Polymer materials: study their crystallization, melting temperature and thermal effects, as well as glass transition temperature, etc.
5. Fiber materials: can be made into 1~2mm length for testing.
6. Powder samples: need to be compacted and ensure that they are not less than 20mg.

Working principle of scanning calorimeter

The differential scanning calorimeter on the SISCO website studies the physical and chemical changes of substances by comparing the heat difference between the sample and the reference at a program-controlled temperature. Specifically, it measures the relationship between the energy difference (or power difference) input into the sample and the reference per unit time and the temperature change.

Application scope

The application scope of the differential calorimeter is very wide, especially suitable for the study of the curing reaction temperature and thermal effect of polymer materials, the phase change temperature and its thermal effect determination of materials, the crystallization and melting temperature and its thermal effect determination of polymer materials, and the glass transition temperature of polymer materials. In addition, it can also be used to detect the phase transition and thermal enthalpy change of solid or liquid samples during constant temperature or variable temperature and is widely used to characterize polymer materials, rubber, fabrics, food, medicine, cosmetics, and other materials.

Main features

1. New furnace structure: better resolution and better baseline stability
2. Digital gas mass flowmeter: precise control of purge gas flow, data directly recorded in the database
3. Instrument control: bidirectional control (host control, software control) is available, with a friendly interface and easy operation
4. Powerful data processing capability: The differential scanning calorimeter is equipped with advanced data processing software, which can automatically record and analyze experimental data. Users can easily obtain key information such as the sample's enthalpy, melting point, glass transition temperature, etc.
5. Multiple test modes: The digital differential calorimeter supports multiple test modes, such as dynamic scanning, static scanning, isothermal scanning, etc. This makes DSC suitable for different types of samples and test requirements.
