Simultaneous Thermal Analyzer (STA)
Model Name: NEXTA STA 200
Manufactured by: Hitachi High-Tech Analytical Science, Japan
Supplied by: Inkarp Instruments Pvt. Ltd., Ahmedabad
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.

- Heating rate: 0.01 °C/min to 100 °C/min.
- Balance design: Horizontal dual-beam design
- Balance housing: Isolated from the furnace and sample chamber
- Forced air cooling (1000 °C to 50 °C within ~20 minutes)
- TGA Balance resolution: 0.05 µg
- Both solid and liquid samples can be tested.
- Built-in mass flow controllers for two gases.
