Our Products

Traditionally, rheometers have been used to characterize the bulk properties of materials. In many materials, such as pharmaceuticals, foods, personal care products and coatings, there is a two-dimensional liquid/liquid or gas/liquid interface with distinct rheological properties. TA Instruments DHR-3 and DHR-2 rheometers offer three geometries for studying the interfacial mechanical properties: the Bicone Interfacial Accessory, designed primarily to measure the interfacial viscosity, the new patented Double Wall Ring (US Patent # 7,926,326), and Du Noüy Ring systems, designed to measure both the interfacial viscosity and interfacial viscoelastic properties. The ultra-low friction nano-torque sensitivity of the DHR-3 and DHR-2 make them the only rheometers in the world capable of measuring bulk rheology, as well as both steady shear and dynamic interfacial properties of materials.
