DMA 303 Eplexor®
Use Dynamic-Mechanical Analysis to gain insights into your material’s mechanical properties
Highlights
The most user-friendly DMA you have ever experienced
Controlled Force Range up to 50 N (static and dynamic)
Our material testing system is designed for precision measurements on very stiff samples with a controlled force range, both static and dynamic, of up to 50 N. The full resolution is available throughout the entire force range, resulting in precise and reliable data.
Temperatures of up to 800°C on the Sample
Featuring the broadest temperature range of -170°C to 800°C and homogeneous temperature distribution.
Time Saving ‒ Fast Heating and Cooling
With its thin-walled 3D-printed silicon carbide furnace lining, our system reduces waiting times with fast heating and cooling and allows for homogeneous temperature distribution due to two independent temperature control loops.
Instant access to important information ‒ Color info display and LED status bar
The integrated LED status bar keeps you informed with regard to the course of the measurement as well as the force, frequency and temperature used.
Back-friendly - highly ergonomic design
The height of the sample holder area can be adjusted, allowing ergonomic work regardless of the user's height or preference for standing or sitting.
Easy on the eyes - Illuminated sample holder area
The integrated light source provides additional illumination and makes specimen and sample holder exchange even more comfortable
Intuitive and tool-less. No more cumbersome exchanging of sample holders and specimens
The instrument allows for convenient switching between a variety of sample holders. It auto-detects sample holders and chooses the correct calibration. The exchange is tool-free and, thanks to fixed guides, sample holders are easy to install.

Excellence in Sample Handling
NETZSCH offers a wide variety of sample holders for its DMA 303 Eplexor®. This results in optimal adaptation of the test conditions to the sample size and stiffness, as well as to the application. For example, a different sample holder is needed to measure a thin polymer film versus a stiff material such as a fiber-reinforced composite.
The RFID (Radio Frequency Identification) technology automatically detects the frame and probe employed and selects the correct calibration in the software.
Method
Dynamic Mechanical Analysis (DMA/DMTA) is an essential tool for evaluating the mechanical characteristics of engineering materials, particularly the viscoelastic properties inherent in polymers.
Changes in a material's viscoelastic behavior can be quantified by subjecting it to dynamic forces and deformations, such as variations in temperature, time, frequency, StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress, atmosphere, or a combination thereof.
How Dynamic Mechanical Analysis Enhances Your Product Commitment
Polymers - Crucial Material in Manufacturing
Polymers offer the advantage of being lightweight and easily adaptable to various shapes through diverse manufacturing techniques. Especially in sectors where plastic components serve pivotal functions, such as automotive, electronics, or medical fields, their performance must align with design specifications. Achieving this necessitates a thorough comprehension of material behavior, spanning from molecular dynamics to tangible mechanical attributes.
Predicting Mechanical Performance - Key to Product Innovation
Dynamic Mechanical Analysis (DMA) emerges as a highly sensitive analytical approach for scrutinizing material traits throughout the design and manufacturing phases. It facilitates the determination of a broad spectrum of mechanical attributes, encompassing stiffness, elasticity, damping, and viscoelastic characteristics.

Software
The latest Proteus® dynamic mechanical analysis software features a clean and easy-to-use graphic user interface that makes it comfortable to navigate and work with the software to its full potential. It saves time by allowing recent measurements to be opened or rerun with ease. It offers predefined templates to help you start new measurements quickly and efficiently. Available templates are designed to meet a range of testing needs and can be customized to suit your specific requirements. The manual control mode grants direct access to static and dynamic load, temperature, and gases. Accurate and reliable results are achieved through calibration routines, which can be carried out by an operator without the need for any external service. During a running measurement, data is represented as an on-line graph with freely configurable axis, or additionally as a list of signals. After the experiment is completed, the data is loaded into the Proteus® analysis software, where extensive evaluation tools are available.

AutoEvaluation, a self-acting evaluation routine for DSC/DMA curves, was designed to evaluate onset temperatures in E‘, peak temperatures in E‘‘, and tan δ for Glass Transition TemperatureThe glass transition is one of the most important properties of amorphous and semi-crystalline materials, e.g., inorganic glasses, amorphous metals, polymers, pharmaceuticals and food ingredients, etc., and describes the temperature region where the mechanical properties of the materials change from hard and brittle to more soft, deformable or rubbery.glass transitions fully autonomously and without user intervention. In addition to its autonomous functionality, the evaluation results that it generates can be taken by experienced users as a second opinion. With AutoEvaluation, you can modify or add calculations of values for the most precise results possible.
Identify allows for the identification and classification of measurements through database comparison. In addition to one-on-one comparisons, Identify can also check whether a particular curve belongs to a certain class. These classes can consist of curves of the same material type (material identification) or of reference curves for Pass/Fail testing (quality control). This feature makes it easy to identify materials and to meet quality control standards.
When working with measurement and evaluation data for different materials and different measurement setups, it is enormously helpful to be able to sort data by certain criteria. Proteus® Search Engine automatically synchronizes your measurement data with pre-defined directories and filters it in a matter of seconds. Previews of measurement curves or analysis statuses are available with just one click.
Users are able to create individual searches, for example “MyPolymers”, and switch easily between different existing searches. This makes Proteus®® Search Engine a very powerful data mining tool.
