The Concentric Cylinder Jacket for the Discovery Core Rheometer enables measurements using cup-and-rotor configurations, ideal for lower viscosity testing. The Concentric Cylinder Jacket utilizes the Discovery Core Rheometer’s integrated Peltier plate andair cooling, providing temperature control over a range of 0 °C to 150 °C. An insulating exterior, conductive interior, and integrated thermocouple ensure temperature uniformity within the sample. The Concentric Cylinder jacket utilizes cup inserts available in a variety of materials and sizes, and Smart Swap 2 upper rotor geometries.
