Original Puck (for use with ALS-style robots only) The ALS-style Puck is a sample pin storage and shipping container compatible with ALS-style sample mounting robots. (This container should not be confused with the V1-Uni-Puck which is compatible with a variety of sample mounting robots.) The puck holds 16 sample pins. It consists of two parts shown in the image: 1) the sample enclosure (left) and 2) the sample base piece (right). Only the sample base piece is magnetic. Each part of the puck has a unique serial number for identification.
