Rheometry is used to evaluate the viscoelastic/rheological properties of solids and liquids. Typical parameters include storage modulus, loss modulus, and viscosity. Beyond analyzing materials over a wide range of temperatures, -160 to 600 C with the Environmental Test Chamber, an ultraviolet accessory is available to characterize UV curing or degradation, and the dielectric properties of materials can be analyzed with the LCR meter accessory. Additionally, a Double Wall Ring is available to perform interfacial rheology.
