The RST-SST is a high end, touch screen rheometer that uses vane spindle geometry in both controlled stress and controlled rate modes to characterize creep behavior as well as yield stress and viscosity profiles.


  • Controlled stress/rate operation to analyze comprehensive flow behavior
  • Capable of measurements in BU units for viscous material such as joint compound
  • Easy test methods for materials with particulate, slurries and stiff pastes with data for viscoelastic characteristics such as yield stress, shear modulus and creep
  • Quantifies properties like wobbliness, sloppiness, consistency and texture
  • Spindle barcode for auto spindle recognition
  • Quick and easy automatic or manual gap setting
  • 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
  • Can also be used with coaxial cylinders for flow curve analysis
  • Optional Rheo 3000 Software for PC control and data management
  • 21 CFR compliance for controlled user access and data security
