Capillary Rheometry Sample Testing

(image for) Call for Price

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.

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
