Frequently Asked Questions About TA Instruments Rheometers

What is rheology?

Rheology is the study of flow and deformation of materials. Deformation and flow are referred to as strain or strain rate, respectively, and indicate the distance over which a body moves under the influence of an external force, or stress. For this reason, rheology is also considered to be the study of stress-strain relationships in materials.

 

What is a rheometer?

A rheometer is an advanced instrument used to measure the flow and deformation behavior of materials, such as liquids, gels, pastes, and polymers, under different conditions. It provides critical insights into the viscosity, elasticity, and other rheological properties of materials, which are essential for product development and quality control.

TA Instruments boasts a curated portfolio of rheometers ranging from core, routine rheology needs, versatile platforms, and the most advanced instrument for research and material development.
