Abstract
A reagent cartridge including (a) a support having reservoirs; (b) a main channel within the support, the channel having first and second ends exiting the support; (c) a pump channel that connects to the main channel between the first and second ends; (d) a valve manifold in the support, including (i) a first passage at the first end of the main channel, (ii) a second passage at the second end of the main channel, (iii) a first master valve between the pump channel and the first end of the main channel, (iv) a second master valve between the pump channel and the second end of the main channel, and (v) reservoir valves for regulating flow from individual reservoirs to the main channel. The valves can be normally closed diaphragm valves formed by magnetic pistons attached to an elastomeric sheet that is sandwiched in the support.
