FLUIDIC CIRCUITS FOR SAMPLE PREPARATION INCLUDING BIO-DISCS AND METHODS RELATING THERETO

摘要

A fluidic circuit for receiving a fluid and separating a component of a fluid from the fluid comprises a separation chamber for receiving the fluid, an air chamber in fluid communication with the separation chamber, and return channel in fluid communication with the separation chamber. In an advantageous embodiment, the fluidic circuit is subjected to a force, such as a centrifugal force, so that substantially all of the component of the fluid is moved to the return channel while substantially all remaining portions of the fluid are moved tot the separation chamber.
