ATS RheoSystems has introduced the Dynalyser, a modular research level rheometer system designed specifically to address the challenging and diverse testing needs and requirements of the serious rheologist. It is designed for testing any rheologically significant materials such as thermoplastics, thermosets, elastomers, semi-solids and fluid systems. This instrument will perform steady, transient, and dynamic shear measurements using parallel plate, cone and plate, couette, rectangular torsion, dynamic tension, and other fixtures. The operation and evaluation software supplied is based on the Windows XP operating system, providing a convenient platform for system networking and instrument operation. For precise control of sample temperature, the system offers an environmental control system with a novel, indirect heated and cooled oven which provides a temperature range from ¿180 to 500 degrees C.
