    Abstract: A rotary rheometer having a an upper heating/cooling assembly and a lower heating/cooling assembly located opposite one another opposite a sample gap. The lower heating/cooling assembly may comprise a Peltier heater and the upper heating/cooling assembly preferably comprises a heating element that mates with a heat spreader for heating and cooling the area above the sample and providing more uniform heating and cooling across the sample gap while also minimizing any chimney effect within the rheometer and/or providing heating/cooling capability that is insensitive to changes in the gap between an upper geometry and the lower heating/cooling assembly. The upper heating/cooling assembly may further comprise a cooling channel for cooling the upper heating/cooling assembly.

    Abstract: A rotary rheometer having a concentric cylinder control jacket and a sample cup. The sample cup fits snugly inside the control jacket, such that the sample cup is in substantial thermal contact with the control jacket along at least the greater part of the length of the sample cup. A heating/cooling assembly such as a Peltier plate, positioned, for example, beneath the control jacket, is used to heat and/or cool the control jacket, thus heating and cooling the sample cup. The sample cup includes a generally annular chamber, which ensures that the sample experiences a uniform temperature. The rheometer reaches steady-state sample temperature more quickly, and the steady-state temperature reached is closer to the actual desired sample temperature than with prior art rheometers, due to the much greater thermal contact between the sample cup and the control jacket.
