Abstract: A self-adjusting tube detector for operating on a plurality of different types of collection containers or tubes including a pivotable adjustment arm which is biased into a first position. The first position is preadjusted for the smallest diameter tube to be utilized. When a larger tube is moved into the aspiration location, the adjustment arm is moved upward against the bias by the tube. The self-adjusting tube detector includes a pivotable reader arm, which is biased into a first position indicating the absence of a tube in the aspiration location. When a tube passes the adjustment arm, the tube will move the reader arm upward to provide a signal indicating that a tube is aligned in the aspiration location for aspiration by the stripper plate assembly.
