摘要：
A container of sample tubes is described with a mechanism for detecting the diameter of variously sized tubes that are placed therein. A method of detection is also described. Both the mechanism and the method rely on pairs of tube holders that are biased together with detectable ends that are spaced farther apart, the larger the tube that is held by the holders. A sensor is provided externally of the container to sense how far apart the ends are spaced.
