A rotatable arm mechanism capable of acquiring two elements simultaneously for purposes of assembly, disassembly and delivery. At one end of the rotatable arm there is mounted a vacuum cup capable of acquiring generally planar elements such as film samples. In addition, there is a pair of tongs extending from the same end of the rotatable arm. The tongs are movable from a converged, non-engaging position to a diverged engaging position such that objects having opening therein such as sample cups and/or rings can be engaged on an inner surface thereof and lifted. The rotatable arm is supported on a linear slide allowing the rotatable arm to be moved vertically. In such manner, the rotatable arm mechanism can reach into open sample cups and deliver thereto or remove therefrom, simultaneously, both a weighted ring and a sample thereby assembling or disassembling such elements. Through further operation of the tongs to engage an inside surface of the sample cup, the rotatable arm mechanism can lift the assembled elements and transport them to another position.
