RST Spindles

The choice of coaxial cylinder, cone and vane spindles accommodates viscosity measurement of a wide variety of materials.
rst spindle
The RSX series Rheometers are available as three different models each with a different spindle geometry:

RSX-CC Rheometers use coaxial cylinder spindle geometry
RSX-CPS Rheometers use cone and plate spindle geometry
RSX-SST Rheometers use vane spindle geometry
RSX-90Y Brabender-type Spindle BU or Brabender Units spindle assembly for the RSX Rheometer and is made from type 304 stainless steel. It can be used for ASTM Standard Method C474, for testing joint compounds
