TA Instruments Discovery X3 DSC

Differential Scanning Calorimeter (DSC)





Acquired in 2023 through an National Science Foundation Major Research Instrumentation grant, the X3 DSC replaced an 18 year old model from the same manufacturer. With minimal downtime and industry-leading technology, this DSC will be a workhorse in AMSEC for years to come.


  • The X3 DSC is capable of running 3 samples simultaneously allowing high throughput with replicate testing and validation/verification.
  • Modulated DSC® for efficient separation of complex thermal events.
  • Fusion Cell™ with patented technology provides unrivaled performance in baseline flatness, sensitivity, resolution, and reproducibility.
  • Tzero heat flow technology guarantees temperature and enthalpy accuracy.


Baseline Flatness (-50 to 300°C) ≤10µW
Baseline Repeatability (-50 to 300°C) <15µW
Temperature Range -90°C to 550°C
Temperature Accuracy ±0.025°C
Temperature Precision ±0.005°C
Enthalpy Precision ±0.08%
Heating/Cooling Rate 0.01°C/min to 200°C/min
