Description

Thermal analysis platform is aimed to the thermo-physical characterization of a wide spectrum of samples (solid (bulk, powder), liquid). The platform includes high tech instrumentation such us Simultaneous Thermal Analysis (STA) coupled with a Mass Spectrometer and Differential Scanning Calorimetry (DSC) for thermodynamic characterization, Laser Flash Apparatus (LFA) and a Dilatometer for physical measurements. The services are provided for research groups within the center as well as to the external users like other research centers or other public organization, but also to commercial companies and private people.

  DISCOVERY HYBRID RHEOMETER (DHR 1) FROM TA INSTRUMENTS

  This rheometer uses FRT technology, provides the most accurate normal force measurement because the linear motor is driven to maintain zero deflection. The FRT and the patented magnetic bearing technologies enable axial Dynamic Mechanical Analysis (DMA) capabilities on every DHR, permitting amplitude-controlled oscillatory deformation in the axial direction. Now in addition to the most sensitive and accurate rotational shear measurements, the DHR can deliver accurate linear DMA data as well without the installation of external components

  Currently we have two different heating systems:

  • Environmental Test Chamber (ETC): an oven working from RT to 600 ºC. For this heating system it is possible to use different geometries. In CIC there are available parallel plates geometries of 25 and 40 mm diameter, and a 4º cone-plate geometry of 40 mm diameter.
  • Electrically Heated Cylinders (EHC): a concentric cylinders geometry with a operating temperature range from RT to 300 ºC.
