The Rosand RH7 and RH10 series of floor-standing capillary rheometers combine maximum force and speed ranges with a robust H-frame design for operation under high loads.
The new digital drive system gives the Rosand RH7/Rh10 outstanding performance in speed control, accuracy and dynamic operating range.
Method
Rheology analyses the deformation and flow of fluids. Traditionally, capillary rheometers have been used to measure the shear viscosity and elasticity of viscous materials at high shear rates.
Our high-pressure capillary rheometers enable controlled extrusion of a sample through a high-precision die. This characterizes the flow properties of a material under high force or pressure and/or high shear rate.
Using the double bore option and a die with unknown length, extensional and shear viscosity can be measured simultaneously as a function of deformation and shear rate. Consisting of several components, capillary rheometry enables a reliable rheological measurement of your specific sample.
Single and twin bore barrel options
for cost effective routine measurement capability through to dual measurements for simultaneous assessment of absolute shear viscosity and extensional (elongational) viscosities.
Maximum drive force (up to 20kN)
and maximum speed (up to 1200mm/min) capabilities enable a wide range of shear rates, and correlation with many real material processing conditions.
