The choice of coaxial cylinder, cone and vane spindles accommodates viscosity measurement of a wide variety of materials.
The RST series Rheometers are available as three different models each with a different spindle geometry:
RST-CC Rheometers use coaxial cylinder spindle geometry
RST-CPS Rheometers use cone and plate spindle geometry
RST-SST Rheometers use vane spindle geometry
RST-90Y Brabender-type Spindle BU or Brabender Units spindle assembly for the RST Rheometer and is made from type 304 stainless steel. It can be used for ASTM Standard Method C474, for testing joint compounds
