Abstract
An apparatus for centering the open end of tubes prior to the insertion of a probe is described. The tube aligning means has a frustoconical inner surface to gather the tube mouth held loosely in a tube rack. The tube is centered relative to the probe. The aligning means is caused to move along the probe shaft axis by cooperation of an outer probe surface and an inner female surface for receiving the probe. In the preferred embodiment, a spool-like cylindrical member is positioned within the arms of a U-shaped bracket which limits the vertical and restricts the rotational movement of the aligning member.
