Rheological evaluation through controlled stress measurement offers superior viscosity profiling, thixotropic response, yield stress determination and creep analysis. The Brookfield RST Rheometer offers both controlled rate and controlled stress measurement. Available with cone/plate, plate/plate, or coaxial cylinder measurement geometry, the RST 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 Rheometer is designed to accommodate the high throughput required of quality control laboratories. It also offers the sophisticated flexibility required of research environments. The RST Rheometer provides cost effective, worry free operation for a variety of laboratory applications.
