DSC 214 Polyma

The System Solution for Efficient Characterization of Polymers 

The New All-Inclusive Product Package for DSC Measurements

Easy-to-use, robust, precise, optimized for everyday use – these are the features of the innovative DSC 214 Polyma. The unique design of this instrument encompasses everything needed for successful DSC investigations – regardless of whether the user is a beginner or an experienced professional. Above all, it is the two new software developments that are setting new standards: AutoEvaluation and Identify. These have the potential to revolutionize DSC analysis.

  • New all-inclusive 360° product package for the characterization of polymers
  • Easier sample preparation than ever before
  • Automated measurement and evaluation

The First Classic Heat-Flux DSC for Fast Cooling

Integrated in the DSC 214 Polyma is an oval furnace with a very low thermal mass (Arena furnace), which allows for heating and cooling rates of up to 500 K/min – values previously unachievable with heat-flux DSCs. Temperature profiles can now be realized which are far closer to real processing conditions.

Groundbreaking Sensor Technology

The novel, patent-pending ring-shaped sensor is comprised of a core of nickel chromium and an outer ring of constantan. Both materials are diffusion-welded. This generates a defined, ring-shaped zone where the temperature under the crucible is recorded, resulting in a significantly higher reproducibility – especially in combination with the Concavus crucibles.

Ideal Combination of Furnace, Sensor and Crucible

By combining a very low thermal mass furnace (Arena) with a robust, sensitive sensor (ring-shaped sensor) and optimized crucibles (Concavus), the DSC 214 Polyma achieves impressive performance data.

Along with fast heating and cooling rates – which also allow for isothermal crystallization experiments – this is expressed particularly by the Indium Response Ratio, which is the achievable height-to-width-ratio of the melting peak of indium.

A high value for the Indium Response Ratio describes a peak that is not only tall (high sensitivity), but also narrow. This allows for the detection of weak effects and, at the same time, for the reliable separation of peaks occurring in close succession.

The DSC 214 Polyma features a high Indium Response Ratio of over 100 mW/K – a value which is not only far greater than average, but actually one of the highest ever published for a DSC instrument.

Software

Proteus 8.0: Software That Frees Time for Other Tasks

A simplified user interface for setting up measurement programs (SmartMode), automatic curve evaluation at the push of a button (AutoEvaluation), and a program for identifying unknown polymer curves (Identify) are the software’s keys to freeing up time for other tasks. Even inexperienced users are able to obtain fast, safe and meaningful results.

DSC specialists can make use of ExpertMode at any time to access the full scope of Proteus software functionality. Results generated by means of AutoEvaluation can be manually post-processed and newly calculated so that the experienced user maintains full control of the evaluation process.

The Proteus software version 8 – especially tailored to the DSC 214 Polyma – runs on Windows 7, Windows 8.1 or Windows 10. It is licensed with the instrument and can of course also be installed on other computer systems.
