Linkam Optical DSC450


Differential scanning calorimetry (DSC) is a technique used to measure temperature and heat flow associated with thermal transitions in materials. The optical DSC450 (Differential Scanning Calorimeter) system has been optimized 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 DSC enables the user to measure thermal and glass transitions of a wide range of substances while accurately controlling temperature from -50°C to 450°C. The atmosphere of the stage can also be purged with gas as required by the user.

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 LNP96 cooling pump is available.

The optical DSC system is ideal for measuring glass transitions, melting peaks and sample purity.


The temperature control range from –50°C (with the addition of a LNP) up to 450°C, for a wide variety of experiments and applications.


The stage can be mounted on to a range of upright microscopes. The stage lid is fitted with a clear quartz window for high quality image capture and recording.


Study thermal transitions at low heating rates, or with small sample sizes, with no loss of sensitivity.


TASC tracks changes in surface structure and is highly sensitive to glass and melt transitions. In addition to the DSC signal, TASC makes it possible to analyse different parts of the same sample to identify inhomogeneities. TASC can be combined with any Linkam thermal stage, creating a modular thermal analysis system.
