Abstract
A toothed sprocket wheel provides an idler for driving test tube holders into and out of sharp turns which occur in the track of an automatic sample changer employed in radiopharmaceuticals. The sprocket is provided with a selected number of well-defined teeth and is rotatably mounted at the center of a relatively sharp turn so as to transfer the linear motion from the test tube holder at its point of entry into the turn to the test tube holder at the point of exit from the turn. Also disclosed is a tensioner or positioner in a substantially linear alignment of the test tube holders such that, upon varying the degree of insertion of the sprocket teeth between successive test tube holders, the relative spacing between successive test tube holders, and the overall test tube holder train length may be adjusted to compensate for expansion/contraction of the holders due to environmental conditions.
