Differential Scanning Calorimetry Optical DSC450

Differential scanning calorimetry (DSC) is a method employed for measuring heat flow and temperature related to thermal transitions in materials. For users wanting to measure the enthalpy variations and transition temperatures of their samples, the optical DSC450 (Differential Scanning Calorimeter) system has been optimized. The design enables mounting the stage on a microscope, allowing time-lapse recording and imaging sample transitions at high resolution.

The optical DSC450 allows the user to measure thermal and glass transitions of a broad array of substances while precisely controlling temperature from −150 °C to 450 °C. The stage contains gas ports to enable purging of the stage to reduce sample oxidation.

The system is equipped with LINK software, a T96 controller, optional Digital Imaging, and Thermal Analysis by Structural Characterization (TASC) modules. The LNP96 cooling pump is available for low ambient temperatures.

Typical DSC curve output from the LINK control software is shown above. The images shown below are the sucrose grain before melting (left) and at the time of melting (right). The optical characteristics of the DSC system enable both image and data sampling throughout the experiment.
