Abstract
A tube restraining apparatus is described for centering the mouth of a loosely held test tube prior to the insertion of a probe. The apparatus is automatically activated by a motor driven carriage and the cooperation of the probe and the bail. The mouth of the tube is centered by contacting the tube rim with the conical inner surface of the restrainer.
