Abstract
Described is a multi-channel fluidic device that includes a diffusion-bonded body having a device surface and a plurality of fluid channels. Each fluid channel includes a channel segment defined in a plane that is parallel to the device surface and parallel to each of the planes of the other channel segments. The plane of each channel segment is at a depth below the device surface that is different from the depth below the device surface for the other planes. Each channel segment may have a volume equal to the volume of each of the other channel segments. One of the fluid channels may include a plurality of channel segments serially connected to each other and each defined in a plane that is different from the planes of the other channel segments.
