Calvet Calorimeter From ambient to 300 °C by Setaram A trademark of KEP Technologies group

C80 The C80 Calorimeter is one of the most powerful, yet flexible calorimeters available. The high precision Calvet detector offers a unique level of sensitivity to thermal events and also the ability to design cells and vessels to simulate almost any potential condition… from pressure up to 1000 bar (14,600 psi), mixing, flow through and wetting. HIGHLIGHTS include: • 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...

SENSOR RODS Ring with 38 thermocouples 3D Calvet Design Sensor The calibration of any calorimetric detector is a key parameter in it’s performance and with the Calvet detector the so-called Joule effect or electrical calibration, is used. A dedicated vessel with a built-in electrical heater (platinum resistance) is used to simulate the experimental vessel containing the sample, and calibration is carried out using a series of precise heat inputs. The main advantages of this type of calibration: t is an absolute calibration I t is not needed to use metallic reference materials I he calibration...

CELLS There is a wide range of vessels available for the C80 calorimeter. The cells can be closed (“batch” type) or combined with fittings to introduce reactive agents (“flow” type). All the cells can be used either in isothermal or DSC mode. "Batch" cell For investigations on solids or liquids: transformation, decomposition, thermal behaviour, heat capacity of solid (a specific cell is available to measure heat capacity of liquid) studies: Cylindrical Hastelloy container with a cap, tightly closed without any link with the outside Available for regular (5 bar) and for high pressures (100 bar)...

Reversal Mixing cell To study the mixing of two substances (solid or liquid) in order to measure the corresponding heat of interaction: ■ Two different compartments are separated by a lid. One substance is placed in the lower compartment, the other in the above compartment. The mixing itself is obtained by inverting the calorimeter (using the reversal mechanism) ■ Available in 3 volume versions (Lower/upper compartment): 0.6ml/5.0ml or 1.3ml/4.2ml or 2.5ml/2.0ml, made of stainless steel or Hastelloy Ampoule Mixing Cell - Immersion calorimetry For studying reaction between a powder and a liquid...

HIGH PRESSURE CELLS There are variety of experiments that need to be studied under pressure, or that may result in pressure evolution and as such there is a range of different pressure vessels available to you. High Pressure “Batch” Cell The High Pressure cell is used when the sample evolves pressure, through a decomposition for example. For investigations on solids or liquids: transformation, decomposition, thermal behaviour, heat capacity of solid or a liquid: ylindrical container with a cap, tightly closed without any link C with the outside High Pressure up to 100 bar – Maximum – Temperature:...

Controlled Static High Pressure Cell To work under controlled and static pressure using a gas panel: to study gas hydrates formation/dissociation, to study adsorption and desorption: ■ Maximum Temperature: 300°C ■ Maximum Pressure: 1000 bar ■ Volume 3.0 ml - Inconel 625 Controlled Dynamic High Pressure Cell To work under dynamic mode (controlled pressure increase or decrease): ■ Cylindrical Incoloy or Inconel container, tightly closed with two introduction tubes ■ For measurements under dynamic pressure up to 600 bar Maximum Temperature: 500°C - Volume: 3.0 ml - Made of Inconel 625 or Incoloy...

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: ■ 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 ■ Process Safety: risks related to accidental pressure build up, synthesis of chemical followed by its thermal decomposition, thermal stability of substances, risks during...
