High precision capillary die assemblies for Rosand rheometers are available in multiple configurations.

  • Additional capillary dies with varying dimensions enable testing of different shear rate ranges and measurement of different viscosity ranges.
  • Capillary die package available to meet ISO1143 requirements.
  • Dies are manufactured from a special grade of tungsten carbide for high wear resistance.
  • Die lengths from nominally ‘zero length’ (0.25mm) to long dies of up to 60mm.
  • Use of a zero length die allows simultaneous determination of shear viscosity and extensional (elongational) viscosity.
  • Die bore diameters from fine bore (0.25mm) up to 3mm.
  • Filled materials may require use of wide bore dies where large particles are present.
  • Die entry angles of 180º and 90º as standard, with other entry angles available on request.
  • User tools available for verification of standard die dimensions and for die cleaning.
  • Special die assemblies available on request.
