The Differential Scanning Calorimetry (DSC) is the most important thermal analysis technique to measure endothermic and exothermic transitions as a function of temperature.
The instrument is used to characterize polymers, pharmaceuticals, foods/biologicals, organic and inorganic chemicals. Transitions measured include glass transition, melting, crystallization, curing, cure kinetics, oxidation induction time and heat capacity.
Unsurpassed performance
- Unsurpassed sensitivity – for detection of melts and weak transitions
- Benchmark resolution – precise separation of close lying events
- Reliable automation – up to 96 position autosampler
- Widest temperature range – from -160 °C to 600 °C in one measurement
The LINSEIS Differential Scanning Calorimeters (DSC) operate in agreement with national and international

Hardware Options
Optical DSC
The L63 DSC can be equipped with
a CCD camera to observe the sample
during the measurement. The visualization of the sample gives a much
deeper insight to phase transitions
and decomposition processes.
UV curing DSC
The Photo cell allows measurements under UV light to investigate UV curing systems. Due to the very short time constant, also fast UV curing reactions in the smallest time scale can be measured.
Sample Robot DSC
The sample robot for up to 96 samples increases the productivity significantly. The instrument can run automatically overnight or at the weekend. Together with the intuitive and intelligent software it reduces labour costs and saves time.
Available accessories
DSC-sample-press
For optimum sample preparation of aluminum
crucibles a ergonomic sample press is available.
Crucibles
Various crucibles made of aluminum, alumina, copper, gold, platinum and sapphire are available for
measurements with the L63 DSC. Other crucibles are
available on request.
User exchangeable Furnaces
The new user exchangable furnace can be replaced
within a few screws. This innovative
concept reduces the maintenance costs drastically
Software
Making values visible and comparable
The software greatly enhances your workflow as the intuitive data handling only requires minimum parameter input. AutoEval offers a valuable
guidance for the user when evaluating standard processes such as
melting and crystallization points. The optional thermal library product
identification tool, provides a database permitting an automatic identification tool for your tested polymer. Instrument control and/or surveillance through mobile devices gives you control wherever you are.

Application
Application example: Cooling rate with an Intracooler
The new DSC system offers an innovative design with a wide temperature range from -60 °C
to 700 °C, without the need for reconfiguring the cooling options. This allows for a more efficient workflow by eliminating time-consuming adjustments. The instrument enables seamless
transitions between low and high temperatures, making it ideal for demanding applications
such as material research, polymer analysis, and quality control. With its high flexibility and
user-friendly operation, this DSC sets a new standard for advanced thermal analysis.
In the graph shown above, you can see how the intracooler ensures efficient and rapid cooling.
Cooling rate | Up to the lower temperature |
|---|---|
| 100 K/min | 560 °C |
| 50 K/min | 240 °C |
| 20 K/min | 40 °C |
| 10 K/min | -30 °C |
| 5 K/min | -48 °C |
| 1 K/min | -60 °C |
Application example: PET Granulate 1. Heating
The analysis of polymers is one of the main applications of DSC. Effects such as glass transitions, melting, and crystallization points are of interest and often challenging to detect. The new LINSEIS L63 DSC offers high resolution and sensitivity, making it an ideal instrument for this type of analysis. With its innovative design, it is now possible
to analyze important properties of the sample even during the initial heating of the PET granulate using the L63 DSC at a linear heating rate of 20 K/min. The curve shows a significant glass transition around 80 °C, followed by a melting peak at 246.20 °C.
Application example: PET Granulate 2. Heating
Depending on the cooling rate, the degree of crystallinity of the polymer changes significantly. During a subsequent heating run, cold crystallization can be observed with a linear heating rate of 20 K/min. The curve reveals a distinct glass transition at around 80 °C, followed by cold crystallization of the amorphous regions starting at approximately 148 °C and a melting peak at starting 230 °C. This allows the complete characterization of the sample with just two heating cycles.
