Micro Reaction Calorimeter

THT offers the micro reaction calorimeter µRC™ with µW sensitivity and 1.5ml disposable vials. This system gives rapid determination of both exothermic and endothermic reaction enthalpies. The use of a computer controlled addition syringe allows highly accurate and repeated titration of reagents.

Versatile and flexible µRC accomplishes most of the tasks of a large volume reaction calorimeter – but faster, simpler, cheaper and safer.

Areas of application

Hazard analysis
Thermal stability
Heat capacity (Cp) determination
