Abstract
Disclosed is an automatic sample changer having a planar upper surface for supporting a continuous chain of test tube conveying pucks. The test tubes being carried by the pucks contain samples such as gamma ray emitting biological samples. A spocket drive gear pulls the pucks into a counting station where the test tubes being carried by the respective pucks are sequentially lowered into a detector region for analysis. After each count is completed, the sample test tube is returned to the surface, and is pushed out of the counting station when the next successive tube-carrying puck is pulled therein. Also disclosed is a disposal site whereby test tubes can be disposed of once the sample has been analyzed, an elevator for lowering and raising the tubes, and a mechanism for enabling the interruption of a long counting operation so as to admit a short count sequence.
