ABSTRACT:
The present invention comprises a reaction cell for a sequencer and the like which includes a sample carrier assembly having a flexible, resilient spacer with a hole therein for retaining the sample on a membrane, a pair of alumina cells which bracket the spacer, one or more pads or spacers to retain the assembly in a tight fitting relation and a cap to secure the assembly together. The reagents are input and withdrawn from opposite edges of the sample membrane. The present invention has a minimal dead volume as a result of the spacer arrangement. It also permits benchtop sample loading due to the separation of the assembly into a carrier and base housing. The fluid lines are self-sealing to the reaction cell.
