Patent ID: 8409527

Claim:
A device comprising: a microfluidic system comprising a first microfluidic channel including at least one inlet and one outlet, a second microfluidic channel including at least one inlet and one outlet, and a reaction area in fluid communication with the second microfluidic channel; a fluidic connector that can be connected to the microfluidic system, wherein the fluidic connector comprises a fluid path including a fluid path inlet and a fluid path outlet, wherein the fluid path includes a first volume, wherein upon connection of the fluidic connector to the microfluidic system, the fluid path inlet connects to the outlet of the first microfluidic channel to allow fluid communication between the fluid path and the first microfluidic channel, and the fluid path outlet connects to the inlet of the second microfluidic channel to allow fluid communication between the fluid path and the second microfluidic channel, wherein the fluid path of the fluidic connector comprises a volume control element that is constructed and arranged to introduce a controlled volume of a fluid sample from a biological entity into the fluid path; and wherein the first and second microfluidic channels are not in fluid communication with one another absent connection via the fluidic connector.
