Where does the NEXTA name come from? The story of our thermal analyzer development.

Materials and raw materials have become highly functional and complex in recent years. As a result, demands for thermophysical property evaluation using thermal analysis, which clarify how the functions and effects of various materials change with temperature in basic research and product development, are also becoming more diverse and complex. 

Compared to single-component samples, complex samples contain a lower percentage of target component, so it’s important to have high sensitivity to detect even the slightest changes. Baseline stability will improve measurement accuracy as well as to eliminate disturbances in the measurement signal caused by the surrounding environment or device conditions as much as possible. 

A key factor for analysis equipment is that they can perform measurements under a variety of conditions and analyze changes in physical properties from a variety of perspectives, in line with the analysis of diversifying samples. To meet these market needs, we’ developed the NEXTA series as our latest thermal analysis instruments. 

We’ve been a pioneer in developing and manufacturing thermal analysis instruments since our first model in 1974. With our NEXTA series, we wanted to bring together cutting-edge technologies that are powered by excellent performance and capabilities. 

That’s why we came up with NEXTA®, an original word that combines ‘NEXT’ to demonstrate the innovative evolution of our thermal analysis instruments and ‘TA’ which stands for thermal analysis. Our NEXTA series of thermal analyzers is our innovative answer to providing state of the art instruments and solutions to help you achieve visibly better thermal analysis.


STA (Simultaneous thermogravimetric analyzer) measures Thermogravimetry (TGA) and Differential thermal analysis (DTA) or Calorimetry (DSC) in one instrument at the same time. It’s commonly used for quantitative analysis of thermal resistance, decomposition temperature and components, and to evaluate specific heat capacity using temperature-modulated DSC. It’s used for research and development and quality control of polymers, pharmaceuticals, foods, electronic devices, ceramics, and metal materials.

In TGA analysis, which reads the difference in mass before and after the mass change, the baseline change affects the reading of the mass change of original sample, so baseline stability affects the measurement accuracy. 

Equipped with a newly designed balance stabilization technology, NEXTA STA has the world’s top-level baseline performance. It can detect slight weight changes over a wide temperature range, confirming that the material meets the required performance and quality standards. The advanced RealView camera system enables real-time observation of the sample during measurement as well as unique analysis like color analysis which only we can provide to deliver visibly better thermal analysis. 

Here’s James, who is one of our thermal analysis experts, showing you a quick demo of the NEXTA STA:


What you’ll get from using our NEXTA STA:

Superior performance:

  • Baseline performance to improve quantitative accuracy
  • Advanced sample observation which diverse color analysis linked with TGA/DTA/DSC data
  • DSC function available in high temperature range where general DSC system cannot support

High safety:

  • Adoption of auto-sampler cover that enhances the reliability of measurements
  • Safety mechanism to prevent overheating with two independent temperature sensors


DSC (Differential scanning calorimetry) measures changes in heat flow for material characterization by providing thermal properties such as melting point, glass transition and crystallization. It’s used for both R&D and quality control in a wide range of industries including polymers, pharmaceuticals, electronics, chemicals, academia, oil & gas, food, and metals. 

As material structures become more complex, it’s difficult to measure various thermal reactions such as glass transition becoming unclear. NEXTA DSC, which has world-class baseline stability, superior sensitivity, and high resolution, can more accurately measure thermal changes in complex materials without missing even the slightest peaks. Our advanced RealView camera system enables measurements from minus degree temperature in addition to our unique color analysis.
