This article is a valuable guide to choosing a rheometer including application, ease of use, configurability, viscosity range, and geometry type. Among the basic types discussed are a rotational rheometer, capillary rheometer, and cone and plate rheometer. Key specifications, parameters, and accessories used in rheometry are covered.
When researching rheometers, the prospective buyer should determine what the system will be used for, be it quality control, process development, or product optimization. By understanding this question, users can home in on the best system to suit their needs, which is not necessarily the most expensive option. Rheometers come in a variety of shapes and configurations. A rotational rheometer basically measures both the force required to stir a material as well as its elasticity, while a capillary rheometer probes how materials behave as they traverse a tube and extrude through an opening—the kinds of events that occur daily during polymer manufacturing.
