microDSC7 evo (microcalorimetry)

the highlights

High-sensitivity DSC and microcalorimetry (-45 to 120°C)

Wide operating temperature range (from -45 °C to 120 °C): cooling of the
calorimeter does not require an external source.

Use in isothermal or temperature programming (DSC) mode.

Possibility to study samples in all forms: liquids, gel, powder, solid.

Variety of closed and removable experimental cells.

DSC measurements under very high pressure (up to 1000 bars):with the use of specific high pressure gas panel and cells.  The microDSC7 is a one of the most flexible microcalorimetry instruments on the market.

Temperature range -45°C to 120°C (Cooling under 0°C requires the use of an auxiliary thermostat)
Programmable temperature scanning rate (heating and cooling) 0.001 to 2 C.min-1
RMS Noise 0.4 µW
Resolution 0.02 µW / 0.002 µW
Cells 1 ml, made of Hastelloy C – Removable Batch, mixing batch, ampoule and high pressure
Pressure (measured & controlled) 400 bar / 5800 psi or 1000 bar / 14 600 psi requires the use of high pressure cells and gas panel

With its wide temperature range (-45 to 120°C), its various cells and its unique capabilities of measuring under high pressure (up to 1000 bars / 14 600 psi), the μDSC7 evo can meet a wide range of applications, especially when dealing with:

• Life Sciences – Pharmaceuticals: protein denaturation / aggregation in liquid, powder or gel form, solid state investigation (polymorphism, amorphism),

• Food: protein denaturation / aggregation, fusion / gelifi cation of polysaccharides, gelatine,
foam formation under gas pressure,

• Polymers: pressure infl uence on glass transition,

• Gas Hydrates: thermodynamic properties of formation / dissociation, stability, kinetics data,

• Petroleum: Gas hydrates formation / dissociation, stability, kinetics data, WAT (Wax Appearance Temperature),

• Environmental: CO2 sequestration (gas hydrates).
