Simultaneous Thermogravimetric Analyzers (STA): NEXTA STA200 and NEXTA STA300

STA (simultaneous thermogravimetric analysis) measures DSC and TGA simultaneously in a single unit. STA is used to evaluate thermal resistance, decomposition temperature, quantitative analysis of components by TGA data, and heat capacity Cp testing with DSC. STA instruments are used in polymer, pharmaceutical, food, electronics, ceramics and metals materials development and quality control.

Our NEXTA STA Series allows you to detect minute weight changes over a wide temperature range, ensuring the material meets performance and quality standards required. Our innovative RealView® camera system provides real-time observation during measurement. Depending on the ambient temperature you’re after, our STA200, STA200RV and STA300 will help to ensure your material meets the performance and quality standards required.

Product Highlights

Every single element designed to deliver a cost-efficient, reliable, and robust system


  • Innovative furnace and balance design deliver ultimate accuracy and precision, even when measuring trace amounts of material.
  • TGA baseline drift and stability of less than 10 µg, allowing you to pick up minute weight loss or gain, even for the smallest sample.
  • Up to 4 mass flow controllers and modulated DSC capability from room temperature to 1500ºC for the most advanced applications.
  • Built-in guidance mode and automated analysis features walk you through the essential measurement steps, ensuring even inexperienced users get the best results.
  • Comes with all available software modules, meaning you can expand your use of the instrument without incurring extra software costs.
  • Data analysis, record keeping, troubleshooting, and reporting made easy to save time.
  • Relevant standards including ISO, ASTM, DIN and JIS with ASTM E1269, ASTM E1641-16, ASTM E794-06, ASTM E793-06, ISO11357-4, ISO 11358-3, ISO 11357-3, ISO 11357-2 and ISO 22768 built into the software.

What makes our STA instruments unique?

RealView® camera for visibly better thermal analysis

The RealView® camera system integrates seamlessly with NEXTA STA Series to observe changes in the sample status during analysis in real-time. Images reveal changes in sample shape, size, colour, and other properties. The images can be recorded and are automatically linked to the thermal data by timestamp. You can also integrate RealView® with the Auto Sampler to monitor changes to your samples while automatically analyzing several samples at once.
