⊙ Titration calorimetry - Isothermal calorimetry - Differential scanning calorimetry 가 모두 측정 가능한 All-in-one 제품
⊙ Solid 및 liquid, mixture 측정을 위한 low volume disposable cell
⊙ 감도가 뛰어나고 (high sensitivity) 측정범위가 넓어 (standard) 생물학적 물질에서 폭발물까지 다양하게 적용할 수 있고,
⊙ 응답속도가 매우 빨라 Kinetic application이 가능하며,
⊙ 10 bar 까지의 압력환경에서 실험할 수 있어서 catalysis와 hydrogen의 모니터링이 가능하고
⊙ Solid addition을 이용하면 정확한 dissolution study가 가능하다.



  Power compensation 원리를 이용한 μRC™는 titration, isothermal, pressure, scanning calorimeter로써 신속, 정확, 간단, 안전, 저렴한 마이크로 반응열량계입니다. Cp 측정은 물론 dissolution study를 위한 solid addition이 가능합니다.

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.
