R/S Plus Controlled Shear Stress/Shear Rate Rheometer.

Available in three versions: R/S Plus-CPS (Cone and Plate), R/S Plus-CC (Concentrical Cylinder) and R/S Plus-SST (Soft Solids Tester).

Rheological evaluation through controlled stress measurement offers superior viscosity profiling, thixotropic response, yield stress determination and Creep Analysis. The Brookfield R/S Rheometer offers both controlled rate and controlled stress measurement. Available with cone/plate, plate/plate, coaxial cylinder measurement geometry, and vane spindles, the R/S 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 R/S Rheometer is designed to accommodate the high throughput required of quality control laboratories. It also offers the sophisticated flexibility required of research environments. The R/S Rheometer provides cost effective, worry free operation for a variety of laboratory applications. For computer control, the Rheo 2000 software is available (not included with the instrument). Note: Rheo 3000 has been released!

• Controlled shear stress/shear rate operation makes it easy to study material behavior from initial yield to flow curve response
  (1 to 6000 sec-1)
• Rugged design means years of trouble-free operation
• Rapid spindle attachment: easy to clean; saves time
• User friendly keypad for simple stand-alone operation
• PC interface for user defined remote control operation. One mouse click will initiate a single or multi-step test.
• More for your money - comparable to instruments costing much more
• Available in coaxial cylinder, vane spindle, cone-plate or plate-plate geometry to suit most any application
• Variety of sample temperature control options: circulating temperature bath, Peltier plate or electronic heating
