A 300 μm deep central chamber with 30 μl inner volume is the reaction cavity of this chip. To keep the components in the chamber either magnetic beads can be used which need to be operated by an external magnet or catcher molecules have to be immobilized on the surface of the cavity. Controlled by two turning valves liquids can be supplied and removed, air pressure can be applied and venting can be ensured. Liquid supply and air pressure are foreseen through the female Mini Luer interfaces on chip.
