Abstract

A system that includes a cartridge housing and a hollow transfer module, according to an embodiment is described herein. The cartridge housing further includes at least one sample inlet, a plurality of storage chambers, a plurality of reaction chambers, and a fluidic network. The fluidic network is designed to connect the at least one sample inlet, a portion of the plurality of storage chambers and the portion of the plurality of reaction chambers to a first plurality of ports located on an inner surface of the cartridge housing. The hollow transfer module includes a second plurality of ports along an outer surface of the transfer module that lead to a central chamber within the transfer module. The transfer module is designed to move laterally within the cartridge housing. The lateral movement of the transfer module aligns at least a portion of the first plurality of ports with at least a portion of the second plurality of ports.
