A device is provided for facilitating the isolation of a fraction from a biological sample. The biological sample includes non-desired material and a fraction-bound solid phase substrate. The device includes an input zone for receiving the biological sample therein and a second zone interconnected to the input zone by a channel. A force attracts the fraction-bound solid phase substrate and is movable along a path between a first position adjacent the input zone, a second position adjacent the channel, and a third position adjacent the second zone. The force has a generally arcuate edge for concentrating the fraction-bound solid phase substrate along the path. The force urges the fraction-bound solid phase substrate from the input zone, through the channel and into the second zone as the force moves from the first position to the third position. |
