Rheometer
CABER operates an AR1500ex (TA Instruments) controlled stress rheometer, which is capable of subjecting a sample to either a dynamic (sinusoidal) or steady shear strain, then measuring the resultant torque expended. The rheometer has been used in the past to measure the way in which a liquid, suspensions or slurry flows in response to applied forces. Samples analysed include silicone oils, polymer solutions & melts, thermal interface materials, biologics, shear-thickening fluids and gels.
A selection of geometries are available, to test a wide range of samples. Several parallel plate geometries with different diameters are suitable for low - medium viscosity specimens or particulate suspensions. A cone and plate geometry is available for very low - very high viscosity specimens or dispersions with particles no larger than 1/10 the geometry gap. Temperature can be controlled with the Peltier Plate, capable of a temperature range of -40 - 200C with an accuracy of +/-0.1C.
