EPLEXOR Series Up to ±500 N

High-Force DMA/DMTA

The testing instruments of the EPLEXOR® series up to ±500 N enable the dynamic mechanical (or static) characterization of a wide range of different materials including elastomers and polymers, composites, metals, glasses, ceramics, biomaterials and foods, adhesives, and liquids.

The modular design of the high-force DMA/DMTA systems allows for measurements in the tension, compression, bending and shearing modes. The testing machines in this series differ from each other mainly in terms of their maximum dynamic force ranges of ±25 N, ±100 N, ±150 N and ±500 N.

Various add-on options make these testing machines a safe investment for the long-term.

All testing machines in this series are conform to standards such as DIN 53513, ISO 6721/1, ISO 6721/4, ISO 6721/5, ISO 6721/6, ISO 4664, ASTM D4065, and ASTM D4473.

Flexible and Set for the Future means of a variety of force and strain sensors as well as furnaces which allow for easy upgrades to the basic system at any time after the first installation

High Force Levels 
...allowing for static loads up to 500 N (optional: up to 1500 N) and dynamic loads up to ± 500 N; especially meaningful for investigations on curable resins, elastomers, composites, metals, glasses or ceramics

Two Independent Drives 
...featuring a servo motor for static and a shaker for dynamic loads

Interchangeable Force Sensors 
...which can be easily changed out by the operator; nominal loads available ranging from ±10 N to ±2500 N

24/7 Operation via the Automatic Sample Changer 
...for tension, compression and bending samples across the entire temperature range around the clock

Optimized for Temperature Sweeps on Large Samples 
...thanks to uniform heating of even large samples with low thermal conductivity (e.g., large rubber specimens)

Highly Economic LN2 Cooling 
...for low liquid nitrogen consumption

Simultaneous Determination of Dynamic Mechanical and Dielectric Material Properties

The comprehensive EPLEXOR® software is based on Windows operating systems. The extensive software package comprises data and curve analyses, hysteresis representation, master curve calculations, etc. 
It also includes specific templates for tension, compression or bending tests.

The software features include:

  • Frequency sweep of 0.001 Hz to 100 Hz (optional 0.0001 Hz and 200 Hz)
  • Temperature sweep (controlled temperature variation at fixed frequency)
  • Time sweep from 1 s to 107 s
  • Correlated temperature and frequency sweep at isothermal steps
  • Correlated dynamic and static strain amplitude sweeps; equidistantly or logarithmically subdivided
  • Master curves (TTS, WLF, numeric mastering), segment tests
  • Evaluation of complex modulus (E*, G*), storage modulus (E’, G’), loss modulus (E’’, G’’) damping factor (t and δ) by temperature sweeps, strain and force sweeps, time sweeps, glass transition temperature, and optional creep, relaxation, fatigue, energy loss, hysteresis, Payne/Mullins effect analysis and crack growth testing
  • Determination of the thermal expansion in tension mode (optional)
  • Prediction of the rolling resistance of tires (optional)  


Sample Holders for a Variety of Applications 
...from liquids via reinforced thermosets to metals and ceramics — all materials can be investigated with the EPLEXOR®.  

Simultaneous DMA/DMTA and DEA 
...for the investigation of transport and relaxation processes on the molecular level.  

UV Add-On 
...for studying reactions which are irradiated by UV light.  

Humidity Generator (HYGROMATOR®
...add-on serves to investigate the water uptake of samples such as plastics and biopolymers. With the humidity generator, it is possible to create relative humidity values of between 5% and 95% in the temperature range between 5°C and 95°C.
