 DSC3 Evo

 

μDSC3 EVO is the new generation of the most popular microcalorimeter of Setaram. Its high sensitivity and versatility makes this instrument a star in many industrial and academic research laboratories all around the world.

 

Highlights

       • Wide operating temperature range (from -20°C to 120°C). Cooling of the calorimeter does not require an external source.

      • Very low detection limit: The μDSC3 EVO detection limit is significantly lower (by a factor of about ten) than that of traditional DSCs. Calorimetric signals of less than one Microwatt can be detected. The very high sensitivity of theμDSC3 EVO enables transition studies to be performed on small quantities of products and at very low programming speeds.

      • Use in isothermal or DSC mode.

      • Possibility of studying samples in all forms: liquid, gel, powder, solid.

      • Large range of experimental cells: including specific cells for studying reactions, providing numerous application possibilities.

 The μDSC3 EVO features the exclusive 3D sensor with Joule effect calibration for highly sensitive and precise calorimetric measurements. Each cell is surrounded by high sensitivity Peltier elements ensuring the thermal contact with the calorimetric block. These detectors are good thermal conductors that keep the temperature in the vessels identical to that in the calorimetric block. Setting the two transducers in opposition on the "measurement" and "reference" vessels eliminates variations common to the two vessels. The heat-flow transducer as defined above enables the μDSC3 EVO to reach a very high sensitivity detection limit of 1μW with excellent measurement accuracy.

The flexibility of the μDSC3 EVO comes from the choice of experimental cells. The cells can be closed (batch type) or combined with fittings to introduce reactive agents (flow type). All the cells can be used in either isothermal or DSC mode. They are made of Hastelloy C, have a volume of approximately 1cm3 and are readily removed and easily cleaned.

Cell Types of Setaram μDSC3 EVO

      • Closed “Batch” Cells for the analysis of raw solid or liquid samples.

      • Cells for Mixing Circulating Liquids to study the mixing of two liquids "'in situ".

      • Ampoule Vessel to study powder wetting or hydration.

      • Fluid-Circulation Cell to study interactions between a fluid and a solid sample.

      • Mixing “Batch” Cell for studying reactions between a powder and a liquid.

      • Heat Capacity Cell to measure the heat capacity of liquids.
