Down ABOUT "BIAXIAL TORSION TESTING SYSTEM"

 

Using an Instron Instrument placed in displacement or load control, the biaxial micro torsion testing system (BMTTS) can accurately determine the torsion and compressive properties of small animal intervertebral disc motion segments and incorporate a load-control constant force upon the disc. The design also incorporates a stepper motor which provides torsion into a GUI in LabVIEW (NI) adapted for an easy interface and better control of data acquisition. The BMTTS is the standard tool for research studies at the Mckay Institute involving the spine and artificial tissue.
