Abstract
An automatic sample changer particularly suited for use in counting biomedical samples from in vitro tests using radiopharmaceuticals such as the technique of radioimmunoassay. A plurality of samples, such as gamma ray emitting samples housed in test tubes, are automatically circulated around a continuous track and are sequentially associated with a radiation counting device by way of an elevator mechanism. A single rotating driving wheel is effective in moving one hundred samples independently travelling on the continuous track. Also disclosed is a breakaway safety mechanism associated with the elevator, and means for detecting and signaling jams in the track and elevator.
