Patent ID: 8871156

Claim:
A microfluidic assembly comprising: a microfluidic assay chip comprising: a plurality of microfluidic channels; two inlet ports associated with each of said microfluidic channels, wherein each pair of inlet ports associated with each microfluidic channel are connected by an interconnecting channel that is in fluid-communication with a proximal end of the associated microfluidic channel; and an outlet port for removing fluid from a terminal end of the microfluidic channel; and an interface cartridge comprising: a plurality of fluid delivery channels in fluid-communication with the interconnecting channel of each of one or more microfluidic channels in the microfluidic assay chip; and a delivery interface configured to fluidly couple said fluid delivery channels of said interface cartridge to the microfluidic assay chip, said delivery interface including a plurality of fluid delivery ports, wherein each fluid delivery port is associated with one fluid delivery channel and is configured to deliver fluid from the fluid delivery channel to an interconnecting channel of the one or more microfluidic channels.
