Abstract:
1. A liquid delivery method comprising: a first step for preparing a rotary substrate capable of rotating in at least a first rotation direction around a central axis of rotation, the rotary substrate being formed with a first chamber spatially closed, a second chamber spatially closed, and a fluid passage having a hydrophobic first fluid passage end portion connected to the first chamber and a second fluid passage end portion connected to the second chamber and connecting the first chamber with the second chamber, the first fluid passage end portion extending from the first chamber in the first rotation direction of the rotary substrate; a second step for accommodating a liquid in the first chamber; a third step for rotating the rotary substrate about the central axis of rotation at an acceleration a a fourth step for abruptly breaking the rotation of the rotary substrate at the rotary velocity RV
