This video demonstrates the use of sutures, hooks, and magnetically mounted pulley brackets for biaxial mechanical testing with the CellScale BioTester.
Paired sutures are used to attach the specimen and looped over pivoting pulleys, creating a force-balanced mounting configuration that enables biaxial loading with minimal shear stress. This approach is particularly useful for delicate materials or specimens where traditional grips are not suitable.
The demonstration shows specimen preparation, mounting using suture brackets, and execution of a biaxial test with real-time force and displacement feedback.
