Dynamic Mechanical Analyser (DMA) for measuring viscoelastic (damping) properties, including storage modulus, loss modulus, storage/loss compliance, tan δ (delta), complex modulus, complex/dynamic viscosity, creep compliance, relaxation modulus, glass transitions, and softening points. The instrument determines changes in sample properties resulting from changes in seven experimental variables: temperature, time, frequency, stress, force, displacement, and strain. The system includes a humidity generator and a Gas Cooling Accessory (GCA) that uses cold nitrogen gas generated from controlled heating of liquid nitrogen.
Available modes of deformation (clamps): dual/single cantilever, dual surface film tension, compression, 3-point bending, and submersion clamp for 3-point bend.
