Advantages include:
• Independent of the matrix.
• Low cost compared with other methods, no maintenance costs
• Non-destructive assay (NDA).
• Possible coupling with gammametry.
General Principle
The calorimeter is of the twin-cell symmetrical heat flow type. It consists of a thermostat-controlled block, opening at the top and surrounding two wells (cavities), each designed to receive a container. One cavity – the sample or measuring chamber – is loaded with an active product, while the other – the
reference chamber – is left empty or loaded with an inactive substance.
The six surfaces of each cavity are covered with flowmetric plates (Peltier elements) that can measure an electrical signal (e.m.f.) proportional to the heat flow between the interior of the chamber and the thermostated block.
As the Peltier elements cover all six surfaces, virtually all the heat flow produced in the chamber and transmitted to the exterior can be integrated.

Our Large Scale Calorimeters are available in different versions:
- 15 liters: Series 270
- 60 liters: Series 390
- 90 liters: Series 680
- and up to 200 liters on special request
