ABSTRACT:
Embodiments of the invention provide an efficient and effective technique for storing and dispensing reagent beads. In one embodiment, an apparatus is provided for dispensing reagent beads contained in a bead storage device which includes a bead carrier having a plurality of wells; a plurality of reagent beads disposed in the wells; and a cover tape releasably attached to the bead carrier to cover the wells and retain the reagent beads in the wells. The apparatus comprises a channel in which to place the bead storage device with the bead carrier facing a support wall of the channel and the cover tape facing a stripping wall of the channel. The stripping wall includes a stripping gap disposed between a stripping edge and an opposite edge, and a dispense opening provided adjacent the opposite edge on a side of the stripping wall opposite from the stripping edge. The cover tape is insertable through the stripping gap to be pulled against the stripping edge to peel the cover tape from the bead carrier to move the wells of the bead carrier inside the channel toward the dispense opening and expose the wells individually to dispense the reagent beads.
