The design is for a holder for multiple biological sample cards. The cards can be placed in parallel in the slots provided in the holder to maximize the density of the cards, and provide for simple mechanical picking of the cards from the holder when the holder is placed in or adjacent a card picking mechanism. The design is intended to be molded from plastics material.
