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