Patent ID: 8327726

Claim:
A microfluidic device comprising: a sample chamber which accommodates a sample; a first sample distribution unit which is connected to the sample chamber and receives the sample from the sample chamber; a second sample distribution unit; a sample transfer unit having an outer wall with a radius of curvature which provides a path for transferring the sample from the first sample distribution unit to the second sample distribution after the first sample distribution unit is filled with the sample, the sample transfer unit comprising a first connection unit which is connected to the first sample distribution unit and a second connection unit which is connected to the second sample distribution unit, wherein a distance from a center of rotation of the microfluidic device to the second connection unit is greater than a distance from the center of rotation to the first connection unit, and the radius of curvature of the outer wall between the first and second connection units gradually increases from the first connection unit to the second connection unit; a first analysis unit which is connected to the first sample distribution unit and analyzes ingredients of the sample received from the first sample distribution unit; and a second analysis unit which is connected to the second sample distribution unit and analyzes ingredients of the sample received from the second sample distribution unit.
