Dynamic Mechanical Analyzer (DMA)
Dynamic Mechanical Analyzer (DMA)
DMA is a electromechanical technique that applies a sinusoidal tensile or compressive deformation, stress or strain, to a sample and measures the viscoelastic response. The frequency and magnitude of the deformation can be held constant or varied during an experiment. The material response to the deformation can be monitored as a function of temperature, frequency, or time. DMA is used to determine a variety of mechanical properties, i.e., complex moduli, storage and loss moduli and damping properties as well as the fatigue behavior. Typical materials tested are bitumen, mortar, mastic and stone-mastic interfaces at a wide range of frequencies and temperatures.Max Force: 450 N (dynamic), 320 N (static)

Dynamic Vapor Sorption (DVS)
Dynamic Vapor Sorption (DVS)
DVS is a measuring system that provides valuable insights into how materials interact with moisture, organic solvents and gases. The DVS can be used to investigate sorption kinetics, moisture diffusion coefficients, Tg and RH phase transitions, and sorption/desorption isotherms of various materials. This technique allows for a better understanding of material behavior in response to environmental conditions, making it an essential tool for characterizing and optimizing a wide range of materials used in various applications, from pharmaceuticals to construction materials.
Differential Scanning Calorimeter (DSC)
Differential Scanning Calorimeter (DSC)
With the PerkinElmer DSC 6000, the thermal response of a material upon heating and cooling can be determined. For binders in pavements, DSC is used to study the melting and the glass transition of binders, among other phenomena, e.g., cold crystallization. It can also be used to conduct forensic analyses of materials used in pavements and other civil engineering structures.Working temperature: -50°C to 300°C.
