If you need rheology or viscosity testing of your raw materials or products, we have the tools,  laboratory resources and experience to give you dependable and reliable results in either steady shear viscosity or viscoelasticity measurements.  Below is an example of the frequency sweep of a linear polymer solution commonly used as a rheology modifier at 10 radians/s and room temperature. 

Frequency Sweep, Viscoelasticity

We can help you select rheology test conditions and test methods best suited for your particular needs. Our practical experience includes numerous pharmaceutical ointments, lotions and creams, foods, beverages, adhesives and other materials that range from low viscosity fluids to soft solids. We can help you put together a suite of measurements or single test to meet your immediate objectives.

Fluid Dynamics, Inc. Is a NJ corporation started in 1994. This year we are celebrating our 29th anniversary.  Fluid Dynamics was started for the purpose of making rheology accessible and meaningful to the R&D and QC industrial community.  For those lacking internal resources, Rheology Central at Fluids Dynamics is an outsourcing resource for testing and research.  We offer a quick turn around generally within 24 hours and maintain confidentiality with all of our customers.
