Multi-Rheometers ™

Multi-Rheometers ™

The DrRheology MultiRheometer™ systems are a new generation of rheometer that perform more than one function. These systems are based on high performance twin bore rheometer technology. The capability is then extended by adding various optional test fixtures. This also includes a range of tensile tests and extensional rheology from lubricated biaxial compression testing. Some of the advanced features on the MultiRheometer systems cannot be found on any other rheometer system.

This means that 1 test system can measure :-1. Shear viscosity. 2. Extensional viscosity through contraction flow. 3. Extensional viscosity through fibre pulling. 4. Extensional viscosity through biaxial compression. 5. Degradation in shear and extension. 6. Gelation. 7. Fracture. 8. Rupture. 9.Wall slip. 10. Elasticity in shear. 11. Elasticity in extension. 12. PVT. 13. Die swell. 14. First normal stress difference.

The systems can measure almost any fluid that flows - from stiff bitumen to aqueous solutions. They can be configured to measure over the temperature range -60c to 500c.

Testing times vary from 10 mins to an hour depending on the complexity of the fluid and the test.
