ABSTRACT:
A jam resistant dispenser (10) including a storage housing (14) of a size and shape to store and dispense a plurality of substantially identical cylindrical members (12), preferably, capillary tubes for gene sequencing reactions and other chemical/biological processes. Housing (14) includes a base (22), an interior (24) defined by a front wall (16), back wall (18), two end walls (20) and the base (22). Base (22) includes an open throat (32) of a size to receive at least seven cylindrical members (12) laid out side by side and parallel to base (22) in order to prevent a naturally occurring arch or bridge of the cylindrical members from forming. Dispenser (10) also includes a sliding tray (46) having an exit slot (48) of a size to completely receive and support one cylindrical member (12). During sliding movement, the exit slot (48) is positionable along any portion of the open throat in order to receive one cylindrical member from the throat. Once the exit slot is filled with the one cylindrical member, the sliding tray is slid laterally to a position where at the extracted cylindrical member is removed from the tray while the tray confronts the base and the open throat so other cylindrical members are not released.
