The balanced pulley sample mounting system is CellScale's attachment method for ensuring zero shear stress during biaxial testing. Two double-ended custom suture hooks are used to create 4 attachment points on each side of the specimen. A two-stage stainless steel pulley mechanism ensures that each of the sutures is held at the same tension during the test.

The pulley mechanisms are magnetically mounted for easy removal for cleaning or replacement and for simple transition between BioRake, Balanced Pulley, and Clamp mounting systems.
