1-139. (canceled)
A microfluidic device, comprising:
- a disc-shaped body having a center region and an outer edge, the body being configured for rotating about a central axis and further comprising:
- a fluid inlet port located in the center region of the disc-shaped body;
- a flow channel having a proximal end, a distal end, and a flow axis, the flow channel in fluidic communication with the fluid inlet port;
- a plurality of fluidic harbors in fluidic communication with the flow channel and offset from the flow axis;
- and
- a fluid outlet port in communication with the flow channel, wherein the fluid outlet port is located closer to the center region of the disc-shaped body than the distal end of the flow channel.

A microfluidic device, comprising:
- a disc-shaped body having a center region, an outer edge and a central axis, the disc-shaped body being configured for rotating about the central axis and further comprising:
- a fluid inlet port positioned in the center region of the disc-shaped body;
- a flow channel having a flow axis and an outermost region, wherein the outermost region of the flow channel is the region of the flow channel that is farthest from the center region, and wherein the flow channel is in fluidic communication with the fluid inlet port;
- a plurality of fluidic harbors in fluidic communication with the flow channel and offset from the flow axis;
- and
- a fluid outlet port in fluidic communication with the flow channel, wherein the distance from the center region to the fluid outlet port is smaller than the distance from the center region to the outermost region of the flow channel.

A method for introducing a first fluid into a microfluidic device, the method comprising:
- providing a microfluidic device, comprising:
- a disc-shaped body having a center region and an outer edge, the body being configured for rotating about a central axis and further comprising:
- a fluid inlet port located in the center region of the disc-shaped body;
- a flow channel having a proximal end, a distal end, and a flow axis, the flow channel in fluidic communication with the fluid inlet port;
- a plurality of fluidic harbors in fluidic communication with the flow channel and offset from the flow axis;
- and
- a fluid outlet port in communication with the flow channel, wherein the fluid outlet port is located closer to the center region of the disc-shaped body than the distal end of the flow channel;
- and
- providing a second fluid to a second fluid inlet port of the microfluidic device.
