Description

TA Instruments ® HR-20 Rheometer consists of bottom and upper plates. Bottom parallel plate is equipped with temperature module to provide testing within set up temperature. Upper geometry plate available in different configurations: parallel plate geometry 20mm, parallel plate geometry 25 mm, parallel plate geometry 20 mm with rough surface for testing of different materials, as well as disposable aluminium geometries of 20mm for testing composites or composed of elastic particles. TA Instruments ® HR-20 Rheometer is suitable for testing of viscoelastic properties of different kind of materials, e.g., hydrogels, ointments, composites. Rheometer allows to work within oscillation, flow and compression modes.
