DesiGn enHAnceD peRfoRMAnce Dynamic Mechanical Analyzer

Dynamic Mechanical Analysis (DMA) is widely used to characterize materials’ bulk properties such as modulus, compliance, and damping (tan delta). It measures changes of rheological behavior under dynamic conditions as a function of temperature, time, frequency, stress, atmosphere, or a combination of these parameters. Stress-strain, creep recovery, thermomechanical, and stress relaxation measurements are just a few examples of the uses of DMA. How can you improve accuracy, sensitivity, and performance? Let us show you.

Quick Glance • Unparalleled flexibility with rotating analysis head • Enhanced performance due to a lightweight analytical train • TMA capability • Superior cooling design • Integrated Fluid Bath option • Controlled humidity studies with a unique humidity generator • Optional furnace window for viewing the sample • Analysis of powders or other difficult to prepare samples The PerkinElmer DMA 8000 is the most flexible, cost-effective Dynamic Mechanical Analyzer available today.

THE ULTIMATE IN DESIGN AND INNOVATION Lightweight drive and clamp system Unmatched cooling capability The novel lightweight analytical train incorporated in the DMA 8000 has minimal compliance and requires no stabilizing springs or air bearing. Due to the design, no shaft support system is required, in contrast to most other DMA instruments, which require either an air bearing or drive support springs. This design offers several advantages for the working laboratory: Because low temperature operation is so important in mechanical testing, the DMA 8000 was designed with an ultra-efficient cooling...

UNPARALLELED FLEXIBILITY TO ACCOMMODATE VARIOUS SAMPLE TYPES Analysis of powders, gels, and natural products Watch your samples Our Material Pockets are a unique sample preparation tool specifically designed to work with the DMA 8000. These innovative pockets allow powdered or non-self-supporting materials, such as powdered drugs, gels, natural products (like tea, coffee, herbs, etc.), and low viscosity materials, to be investigated by DMA. Applications include detecting small amounts of amorphous material in samples that cannot be formed into a bar or a material naturally occurring in a powder-like...

Single Cantilever Bending Dual Cantilever Bending The sample is anchored on one end by a fixed clamp and by the drive shaft on the other. Bending stress is applied by the motor. The sample is anchored on both ends by a fixed clamp and by the drive shaft at the mid point. Bending stress is applied by the motor. Sample is anchored on one end by a fixed clamp and by the drive shaft on the other. Tension stress is applied by the motor. Sample is sandwiched between a fixed plate and a plate mounted on the drive shaft. Compression stress is applied by the motor. Two samples are sandwiched between two...

NUMEROUS EXPERIMENTS, ONE EASY SOLUTION Immersion experiments Controlled humidity experiments The DMA 8000 environmental Fluid Bath option has been designed as an integral part of the analyzer. The accessory allows true immersion studies on a sample while measuring the dynamic mechanical properties. All geometry modes are supported in immersion mode. The temperature range of the Fluid Bath is from subambient temperatures to 150 °C. A further unique capability is that the low-end temperature can be extended to -196 °C when liquid nitrogen is used as the immersion fluid. The immersion fluid can...

MEETING YOUR APPLICATION NEEDS Instrument control Advanced Experimental Procedures Operation of the DMA 8000 is through PerkinElmer's well known Pyris Software. This software operates our thermal analysis line and allows overlay of data from various instruments. For the DMA, it allows easy-to-use operation and analysis. Time Temperature Superposition Software (TTS) and Stress Relaxation Software are also included with the DMA. TTS allows the prediction of material properties at frequency ranges not obtainable in any commercial instrument. Stress Relaxation allows a greater understanding of how...

Use of Material Pockets for mechanical analysis Figure 1 shows tan S data from two DMA experiments with polystyrene. The original sample was the same, but the red ine shows an experiment run with a bar sample in Single Cantilever Bending. The black line shows an experiment run with grated polystyrene in a Material Pocket. Both were run at 1 Hz. It is clear that the glass transition, shown as a peak in the tan S data, is the same for both experiments. The peak value is less for the Material Pocket, but this is a reflection of the lower sample mass. This experiment demonstrates that it is possible...
