A removable cap for use with a test tube or the like has metallic characteristics associated therewith, in order to facilitate the handling of the test tubes in hostile environments. The cap has a recess provided therein which extends from a first surface toward a second surface. A metallic member is positioned in the recess and a second cap member is positioned over the recess, the second cap member cooperating with the recess to maintain the metallic member in position in the recess. The cap is attached to the test tube, so that when a magnetic rod is position over the removable cap, the metallic member is attracted to the magnetic rod, causing the cap and test tube to be moved.
