Linkam-Optical DSC450

Differential Scanning Calorimetry with imaging, temperature control from < -150°C to 450°C




Differential Scanning Calorimetry (DSC) is a technique used to measure the
temperature and heat flow associated with thermal transitions in materials.
The optical DSC450 system has been optimised for those wishing to measure
the transition temperatures and enthalpy changes of their samples. The design
allows mounting of the stage on a microscope, enabling image and time lapse
recording of sample transitions at high resolution.

The optical DSC450 allows the user to measure thermal and glass transitions of
a wide range of substances whilst accurately controlling temperature from
-150°C to 450°C. The stage has gas ports to allow purging of the stage to
minimise oxidation of the sample.

The system is provided with a T96 controller, LINK software and optional Digital
Imaging and Thermal Analysis by Structural Characterisation (TASC) modules.
For below ambient temperatures, the optional LNP96 cooling pump is available.

Above is a typical DSC curve output from the LINK control software. Below are
images of a sucrose grain prior to melting (left) and during melting (right).
The optical feature of the DSC system allows both data and image sampling
throughout the experiment.
