1. A fluidic device assembly comprising at least two microfluidic devices in a disposable cartridge, wherein each fluidic device comprises:
a) a first port;
b) a first fluid transport channel in fluid connection with:
i. the first port;
ii. a reaction well; and
iii. an overflow channel;
c) a second fluid transport channel in direct fluid communication with the overflow channel;
