RST Coaxial Cylinder Rheometer

This instrument is no longer being manufactured, effective 14 March, 2022. Please refer to the AMETEK Brookfield RSX Rheometer.
RST-CC 201x583

Rheological evaluation through controlled stress and controlled rate measurements offer superior viscosity profiling, thixotropic response, yield stress determination and creep analysis. The RST-CC Rheometer offers powerful flow characterization tools including ramp, loop, and single point testing. A wide range of shear rate, shear stress, and torque provide flexible flow analysis including creep and yield measurement. The RST-CC Rheometer is designed to accommodate the high throughput required of quality control laboratories providing cost effective, worry free operation for a variety of laboratory applications.
