RST Cone Plate Rheometer

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

The RST-CPS Rheometer is great for cone and plate as well as plate to plate system for small volumes and wide shear rate ranges.

 Rheological evaluation through controlled stress and controlled rate measurements provide comprehensive viscosity flow curves, thixotropic response, yield stress determination creep analysis and viscosity vs. temperature profiling.


  • Controlled stress/rate operation to analyze comprehensive flow behavior
  • Spindle barcode for auto spindle recognition
  • Quick and easy automatic or manual gap setting
  • Rapid temperature control of plate with Peltier option for quick profiling of viscosity vs. temperature
  • User-friendly LCD touch screen with graphical display
  • 11 memory slots for structured multi-step test programs
  • Auto spindle identity recognition
  • Quick connect coupling for easy spindle attachment
  • Optional Rheo 3000 Software for PC control and data management
  • 21 CFR compliance for controlled user access and data security
