DSC differential scanning calorimeter -100 ° -600 °

Differential Scanning Calorimetry (DSC), as a classic thermal analysis method for thermal effects under controllable program temperature, has been widely used in various fields of materials and chemistry, including research and development, process optimization, quality control, and failure analysis. By using DSC method, we can study the phase transition of inorganic materials, the melting and crystallization process of polymer materials, the polymorphic phenomenon of drugs, and the solid/liquid phase ratio of foods such as oils and fats.
