Supporting R&D to Manufacturing.

Yield Stress


Other Assays


Knowing your sample viscosity may be important; however, understanding its more detailed rheological profile and potential implications may be highly value added and critical.

Rheology Testing Services (RTS) offers an array of analyses to support early R&D through manufacturing across many materials and industries.  These assays efficiently and precisely probe material response to various forces and conditions to model processes and applications to which your material may be exposed.  Material that is exposed to force, however minimal - even gravity, may reversibly or even irreversibly change from the effects of stress, shear, strain and temperature.  Output from these assays, described in more detail in the above tabs may provide better understanding of your materials to support R&D, process optimization, manufacturing, packaging, performance, efficacy, and tactile properties.  Other applications include regulatory considerations to demonstrate or disprove structural equivalence (Q3, ref 1-3), in-process control, batch consistency and stability.
