Simultaneous Thermal Analyzer (STA)

About:

The Hitachi NEXTA STA 200 is a simultaneous thermal analysis system that combines Thermogravimetric Analysis (TGA) and Differential Thermal Analysis (DTA), with DSC conversion capability, in a single instrument. It is used to study weight changes and thermal events of materials as a function of temperature and time. The system is suitable for polymers, composites, nanomaterials, metals, ceramics, and inorganic materials under controlled atmospheres. These measurements are important for materials development, process optimization, quality control, and performance evaluation.
