Capillary rheometry

In a capillary rheometer, shear is generated by a pressure difference over a closed channel.  Gravity, compressed gas or a piston are used to generate pressure on the test fluid. The pressure drop and flow rate through a capillary tube are used to determine the fluid's viscosity and other rheological properties.

Some of Arkema Analytical Solutions' specialized capillary rheometry capabilities include:

  • Various die geometries
  • Sub-ambient temperature testing
  • Rheotens attachment for determination of polymer melt strength and extensional viscosity
  • Dynamic die swell measurement
  • PVT attachment for determination of specific volume as a function of temperature and pressure
