The Highlights
Reaction, isothermal and scanning calorimeter (ambient to 300°C)
Incomparable precision of measurement: the 3D Calvet sensor totally surrounds the sample, and all heat evolved is measured. Now matter how small or large the thermal transformation the system provides a complete picture of the event.
Absolute calibration: with a three-dimensional transducer the sensitivity of the C80 is independent of:
The weight, form and nature (powder, fiber, liquid, etc.) of the sample
Any contact between the sample and the transducer
The type of crucible used
The nature of the sweeping gas (inert, oxidizing, wet) and its flow rate.

Flexibility using the power of the detector, and the wide range of available vessels the C80 calorimeter offers the ability to simulate almost any process condition:
Isothermal calorimeter: the heat measurement is performed at a constant temperature
Scanning calorimeter: the heat measurement is performed during a temperature program
Reaction calorimeter: mixing vessels allow for the simulation of reaction conditions, liquid/liquid, solid/liquid and even gas phase reactions can be measured.
Cp Measurement, liquids, solids and powders
Heats of solution and many more.
Ease of operation: dedicated market leading CALISTO software that is not only intuitive but powerful enough to perform every typical experiments and data treatment.
NEW PARTS AND OPTIONS
Vessel for vapors dosing
A specific vessel that allows for connection with a vapors dosing system was designed for the C80. It can withstand pressures as high as 200 bar. The introduction tube of the vessel is heated up to 250 °C with a dedicated thermostated cover to avoid vapor condensation. |

APPLICATIONS
With its temperature range (ambient to 300°C) and its large range of cells the C80 calorimeter can meet a wide range of applications, especially when dealing with:
Process Safety: risks related to accidental pressure build up, synthesis of chemical followed by its thermal decomposition, thermal stability of substances, risks during normal operations, risks during an accident, time & mass scales.
Life Sciences: Pharmaceuticals Products: polymorphism detection by dissolution studies, behavior of a drug under a wet atmosphere, study of polymorphism / crystallinity of drugs, amorphism, metabolism of living species, thermal stability of intermediate products.
Energy: desulfurization of diesels by zeolithes, measure of reactivity of asphalt-salt mixtures, gas hydrates formation / dissociation, catalyzers characterization, adsorption of hydrogen (fuel cell), stability of nuclear waste, thermal characterization (nuclear).
Food: neutralization of free fatty acids in oils, gel formation / dissociation, dissolution studies, melting, crystallization, amorphism, stability vs. oxidation.
