TA Instruments ARG2 Rheometer


The AR-G2 is an advanced controlled stress, direct strain and controlled rate rheometer with a magnetic-levitation thrust bearing and a drag cup motor to allow nanotorque control. The magnetic bearing allows frictionless axial support and measurement of ultra low torques from 0.03 uN-m up to 200 mN-m with a resolution of 1 nN-m. Velocities up to 300 rad/s with a displacement resolution of 25 nrad can be applied; dynamic frequency range is 7.5 x 10(-7) to 628 rad/s. Temperature control is achieved using a Peltier plate. Custom environmental chambers and grip plates have been created for multiple unique biological applications.

Shock Tube

Capabilities: Our shock tube can generate pressure waves approximating the Friedlander waveform for blast research. Human Infant Finite Element Model • Tube length of 15’ and internal diameter 6” • Driver overpressures ranging from 10 to 60+ PSI • Closed end or open ended testing • Diaphragm manually punctured using pneumatic activated arrowhead • Varied driver gases to create desired pressure profiles Instrumentation: 8 sensor ports along the length of the driven section of the tube allow for pressure measurements. • Pressure sampled at up to 1MHz • PCB Piezotronics pressure sensors
Optokinetic Tracking Behavioral Test Unit

Capabilities: This custom device was designed to assess functional visual acuity for animal studies. Rotating contrast grating causes head tracking behavior when acuity sufficient to see the pattern. Human Infant Finite Element Model • Supports rat and mouse vision testing • 360 degree stimulation • Allows both light and dark adapted vision testing through the use of neutral density filters and infrared camera to track animal behavior Software: In-house Matlab program uses Psychtoolbox to present drifting stimulus across four computer monitors. • Testing algorithm designed to eliminate testing bias from knowledge of drift direction • Contrast of grating varied automatically in a 2 down 1 up algorithm to assess visual acuity threshold • Spatial Frequency and Rotation Speed can be varied to test specifications.
