SPECIFICATION
-10 °C to 200 °C [Temperature range]
0.5 μW ~ 10 mW [high]
5 μW ~ 300 mW [standard]

THT introduce 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.
