✦ Synopsis

A simple, automatic sample-changing device for commercially available gamma counters is described. Plastic beads, with centrally pierced orifices serve as holders (containers) for the radioactive samples. The principle of the device is based on sorting out the contamers (i.e., the beads) by gravity-fed transmission into the counting chamber. Following the completion of counting, the samples are removed from the chamber and the cycle repeated. The successful operation of this device is demonstrated by its application to microscale polyacrylamide disc gel electrophoresis.
