It can also be used to measure expansion or contraction, tack testing for adhesives, compression set of rubber o-rings, and much more. This comprehensive set of information is invaluable for method development, procedure deployment and data validation. 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.
The new DMA Express interface is designed specifically for new users dmma those with simple, well-defined experimental requirements it presents test setup details q080 easy-to-choose, self-contained forms.
If it is too small, force sensitivity suffers. The intuitive user interface allows you to simply and effectively program experiments, and move easily between processing experiments and viewing and analyzing data.

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.
In oscillation experiments, the instrument uses constant and variable methods to apply a static load that prevents buckling and unnecessary creep. For the first time, design test procedures that contain any combination of available test types including oscillation, transient, strain- and stress- control, mechanical and thermal conditioning, and more.
A unique low-friction, roller bearing supported design available on the 20 mm and 50 mm clamps improves modulus accuracy and reproducibility by accommodating and accounting for twist or curvature in the test specimen.
Systems without this design feature suffer from poorly controlled deformation in unsupported designs, or diminished sensitivity where spring guidance is employed. Sample spans of 5 mm, 10 mm, 15 mm, 20 mm, and 50 mm are available to accommodate a wide range of sample stiffness and specimen sizes. DMA Photo Gallery. 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 Standard Furnace without additional circulators or environmental systems.
Tensile clamps are designed 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. Choose from the core DMA Express test modes plus advanced sample conditioning, deformation, conditional step termination, and repeat segment capabilities. DirectStrain is real-time strain control for faster and more accurate measurements of challenging samples and test conditions, such as rapidly changing materials or soft specimens at high frequencies.
The motor is constructed of high-performance lightweight composites that maximize axial and torsional stiffness while minimizing system inertia.
Non-contact, low mass motor delivers continuous forces from 0. Gain actionable insights into your material behavior through a powerful and versatile set of features seamlessly integrated into TRIOS. 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 limits.
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. Optimized Mechanics 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.
The user is presented with all necessary testing parameters in a self-contained window, populated with q80 default starting parameters. Complete Data Record The advanced data collection system automatically saves all relevant signals, active calibrations, and system settings. A summary report provides calibration status at a glance and ensures data integrity.

Available in sample lengths of 8 mm, 20 mm, and 35 mm, the cantilever clamps can be used in q800 or dual configurations. Parallel plate compression measurements are most suitable for low to moderate modulus materials such as foams and elastomers.
Ergonomic design for easy viewing and operation Packed with functionality to simplify operation and enhance user experience The app-style touch screen includes: The DMA offers your choice of two dedicated environmental systems: Shear Sandwich 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. Go beyond conventional DMA testing and program experiments that mimic complex real-world conditions through an unlimited combination of 23 available steps. Each clamp is individually optimized da accuracy and ease-of-use. If the deformation chosen is too large there could be excessive sample creep.

The system successfully prevents condensation, a common occurrence in controlled-humidity environments which makes accurate control of relative humidity impossible. The app-style touchscreen, powerful new TRIOS software, and quick robust calibration routines work seamlessly to dramatically improve laboratory workflows and productivity.
Temperature-Controlled Transducer The transducer is temperature-controlled to eliminate drift associated with temperature changes from the sample or laboratory environment. A newly designed film tension clamp simplifies the clamping mechanism to improve ease-of-use, clamping uniformity, and effectively prevents sample slippage.
The penetration kit is designed for higher stiffness materials and local measurements through the use of smaller probes: Waveforms for each data point may be displayed as Lissajous plots and provide a visual representation of the stress-strain relationship.
The result is the most stable platform for mechanical characterization of materials even under dmq conditions. The transition temperatures of loose powders can be difficult to measure by mechanical techniques.
DirectStrain Faster electronics, all new digital signal processor DSP controls, and an enhanced drive system allow for an all-new type of strain control in the DMA
