Stress RheometerPolymer Synthesis/Characterization, Stanford University
TA Instruments AR2000ex Rheometer. The design of this instrument includes a uniques an ultra-low inertia drag cup motor and porous carbon air bearings for outstanding controlled stress, direct strain and controlled rate performance. The AR2000ex features an original quick-interchanging and self-configuring environmental system. The high resolution optical encoder, high stiffness low inertia design make the AR2000ex extremely versatile and appropriate for a wide variety of applications including characterization of delicate structures in fluides of any viscosity, polymer melts, solids, and reactive materials.
