A 2-point flexure test kit for determining the kink resistance of guidewires, designed for forces up to 50 N. Grip-to-grip separation is infinitely adjustable and the kit includes a dial gauge for displaying grip-to-grip separation from 0 to 55 mm, with an accuracy of 0.1 mm. Specimen clamping is in the vertical plane, with the bending angle (max. 90°) generated via the rotating clamping unit.
