The rectangular shape of the drive shaft completely eliminates off-axis motion. View brochure Contact Us. The only limit is your imagination! Available in sample lengths of 8 mm, 20 mm, and 35 mm, the cantilever clamps can dm used in single or dual configurations. The app-style touchscreen, powerful new TRIOS software, and quick robust calibration routines work seamlessly to dramatically improve laboratory workflows and productivity.
For the first time, design test procedures that contain any combination of available test types including oscillation, transient, strain- and stress- dmma, mechanical and thermal conditioning, and more.
The all new intelligent Auto-Ranging feature takes the guess work out of selection of starting conditions and ensures force and displacement are automatically maintained within reasonable user defined ddma.
The DMA offers your choice of two dedicated environmental systems: Accurate sample temperature is obtained by a thermocouple placed within the fluid reservoir and close to the sample Inert stainless steel construction and a seal-free design ensure compatibility with a wide range of fluids Temperature control provided by the A800 Furnace without additional circulators or environmental systems. Photorealistic images and clear instructions reduce operator training time by guiding them through simple procedures.
DMA Q – Analysis Quickstart – TA Instruments
The standard compression kit includes parallel plates of 15 mm and 40 mm diameter, ideally designed for bulk measurements of moderate to low stiffness samples. The result is the most stable platform for mechanical characterization of materials even under extreme conditions. The slide is guided by eight porous carbon air bearings. Because the modulus of a material can change by several orders of magnitude in a narrow range of time or temperature, the selection of programming parameters can make or break an experiment.
The sample chamber mounts directly to the DMA. Temperature-Controlled Transducer The transducer is temperature-controlled to eliminate drift associated with temperature changes from the sample or laboratory environment.
Onset and endset analysis Signal maximum and minimum Signal change Modulus crossover Curve values at specific X or Y points 1 st and 2 nd derivatives Area under the curve Peak height Peak integration, and running integral Mathematical fitting: Tension Tensile clamps are designed for uniaxial deformation of films and fibers.
A new self-aligning mechanism ensures the parallelism of upper and lower plates, enhancing strain and force uniformity while simplifying user interaction and improving modulus accuracy and precision.
The system successfully prevents condensation, a common occurrence in controlled-humidity environments which makes accurate control of relative humidity impossible. The critical drive components of the DMA are mounted within a high-stiffness aluminum casting that is rigidly mounted to an FEA-optimized instrument frame.
This new capability unlocks complete material characterization under virtually any set of test conditions. Sample spans of 5 mm, 10 mm, 15 mm, 20 mm, and 50 mm are available to accommodate a wide range of sample q00 and specimen sizes. A comprehensive set of dmw tools are available for real-time data analysis, even during experiments. Competitive systems based on moveable, hanging, or soft-mounted frames are constrained in their effective frequency-range by the combination of sample stiffness and system resonance.
Only TA offers clamps that are ready to use out of the box without complex assembly procedures inherent to competitive designs. Benefits of Direct -Strain include: The new DMA Express interface is designed specifically for new users and those with simple, well-defined experimental requirements it presents test setup details in easy-to-choose, self-contained forms. Each clamp is individually optimized for accuracy and ease-of-use.
Visual guides aid in aligning film samples and integrated supports simplify fiber testing. Go beyond conventional DMA testing and program experiments that mimic complex real-world conditions through an unlimited combination of 23 available steps.
With this new capability, the DMA can perform a complete material characterization protocol under a diverse test conditions in a single experiment, or apply mechanical conditioning immediately followed by characterization.
Cantilever clamped bending is a good general-purpose mode for evaluating thermoplastics and highly damped materials e. Gain actionable insights into your material behavior through a powerful and versatile set of features seamlessly integrated into TRIOS.

The q80 drive motor transmits force directly to a rectangular air bearing slide. The powder accessory for the DMA is used with the dual cantilever clamp to observe transition temperatures of loose powdered materials by DMA, combining the enhanced sensitivity of mechanical analysis with the simple sample preparation of powder characterization techniques.
A summary report provides calibration status at a glance and ensures data integrity. In oscillation experiments, the instrument uses constant and variable methods to apply a static load that prevents buckling and unnecessary creep. The DMA is the only commercial DMA instrument to feature a temperature-controlled force and displacement transducer, providing unparalleled measurement stability and accuracy.
Two equal-size pieces of the same material are sheared between a fixed and moving plate for the measurement of shear modulus, G. Stable, responsive peltier elements precisely control sample temperature while calibrated digital mass flow controllers deliver pre-heated gas of the prescribed ratio to achieve the target humidity. Tensile clamps are dmaa for uniaxial deformation of films and fibers.
This enables the system to capture a broad spectrum of material properties with the highest level of sensitivity and accuracy.

It dmma also be used to measure expansion or contraction, tack testing for adhesives, compression set of rubber o-rings, and much more. This precision environmental system provides accurate control of sample temperature and relative humidity for DMA experiments.
For routine use and common test types, DMA Express shortens training time, reduces the possibility for mistakes in experimental design, and inspires confidence. The motor is constructed of high-performance lightweight composites that maximize axial and torsional stiffness while minimizing system inertia.
Compression Parallel plate compression measurements are most suitable for low to moderate modulus materials such as foams and elastomers. If it is too small, force sensitivity suffers. This field-proven design provides for efficient and precise temperature control over the entire temperature range in heating, cooling, and isothermal operation.
