Two Personalized-manufactured stainless steel grips have been used in a microtensile exam rig (UniVert, CellScale, Waterloo, ON, copyright) to connect the wire specimens. Stainless steel tubes have been milled to fit the actuator and foundation parts on the UniVert machine and aligned rigidly in a similar axis with the actuator. https://www.ortix.co.uk/wires/
