High-Precision GS-TGA1250 Electronic Thermal Analyzer – TGA/DSC, RT–1200°C

The GoldSu GS-TGA1250 is a high-precision simultaneous thermal analyser (STA) combining Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC/DTA). It allows the study of weight changes, thermal transitions, and heat flow in materials under controlled temperature conditions from room temperature up to 1200°C.

This analyser is designed to investigate the thermal stability, composition, decomposition, reaction kinetics, and moisture or volatile content of materials. It is widely used in research and development, process optimisation, and quality control in industries such as plastics, rubber, coatings, pharmaceuticals, catalysts, metals, and composites.
