Refrigerated cooling Thermogravimetric-Differential Scanning Calorimeter (TG-DSC)
Enables low-temperature measurements from -40°C and controlled cooling beyond conventional limits
Refrigerated Cooling STAvesta Overview
For details on the basic performance of STAvesta, please refer to the main STAvesta page.
In gas adsorption studies using CO₂ and similar gases, lower temperatures generally increase the amount of gas adsorbed. Therefore, measurements below room temperature are often required. STAvesta/LR meets this need by enabling evaluation from as low as -40°C, making it possible to analyze gases that are difficult to adsorb at ambient temperatures and to more accurately assess the performance of adsorbent materials.
The unit also allows heating up to 700°C, making it suitable for pretreatment processes such as gas desorption from materials. By utilizing programmable heating and cooling sequences, both pretreatment and adsorption/desorption analysis can be performed in a single continuous run.
In addition, the optional automatic sample changer allows for automated, continuous measurement of multiple samples.
