DMA 242 E Artemis
Dynamic Mechanical Analyzer
The Most Versatile DMA in the World

The new DMA 242 E Artemis combines ease of handling with the user-friendly Proteus® measurement and evaluation software. This makes it fast and easy to characterize the dynamic mechanical properties as a function of frequency, temperature and time.

Its modular design along with a wide variety of sample holders and cooling systems allow the DMA 242 E Artemis to handle a broad range of applications and samples.

Various add-on options make it the ideal device for any laboratory and a safe investment for the long-term.

Hang-down design : for easy accessibility, handling and changing of the different sample holders

Over 30 different sample holders :for optimal adjustment of measurement conditions to material properties

Controlled gas flow (inert or oxidizing) :with optimal heat transfer on samples for defined measurement conditions

Various cooling options. :Two different cooling systems; liquid nitrogen-controlled cooling to -170°C and compressed-air cooling with vortex tube to cool to 0°C

Controlled force range up to 24 N :(12 N static and 12 N dynamic) for measurements of very stiff samples. Increased resolution in the measuring range 4 N static and 4 N dynamic

A stepper motor with a 20-mm travel range :allows for precise testing on materials which exhibit substantial changes in length during a DMA measurement. This is particularly important for the different static experiments available with the DMA 242 E Artemis; i.e., creep, relaxation and TMA mode.

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, 50 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
...by 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 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 5000 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
