Simultaneous Thermogravimetry- Differential Scanning Calorimetry (STA/TG-DSC)

STA 449 F1 Jupiter®

 

Fascinating Flexibility in Thermal Analysis

 

The STA 449 F1 Jupiter® combines unlimited configuration flexibility and unmatched performance in just one instrument.

• Thermal stability, decomposition behavior, composition, phase transitions, melting processes to be analyzed comprehensively and quickly

• Easily to use top-loading system with exceptionally precise balance resolution (25 ng resolution at a weighing range of 5g) and highest long-term stability

• Interchangeable sensors for DSC measurements with highest sensitivity and best reproducibility for reaction/transition temperatures and enthalpies as well as for measurements of specific heat(videoclip for sensor exchange)

• A variety of optional system enhancements for ideal system adaption to user-defined applications

• Various furnaces, easily interchangeable by the user, available (optional a swiveling double hoisting device for two furnaces) - please see accessories

• Pluggable sample carriers (TGA, TGA-DSC, TGA-DTA, etc.)

• Automatic Sample Changer (ASC) for up to 20 samples

• Automatic evacuation and refilling (AutoVac)

• Plenty of accessories, e.g. sample crucibles in the most varied of forms and materials

• Unique for STA: temperature-modulated DSC (TM-DSC)
