Abstract: A liquid delivery apparatus 1 has a rotary substrate 2. The substrate 2 formed with a fluid passage 8A for communicating a supply chamber 6A and target chamber 7A. An inlet end portion 13 at which the fluid passage 8A is connected to the chamber 6A extends in a clockwise direction R1 of rotational directions of the substrate 2. The inlet end portion 13 holds a liquid 9 in the chamber 6A by a capillary force. The rotation drive unit 4 rotates the substrate 2 so that an inertial force exceeding the capillary force and directed to the clockwise direction R1 acts on the liquid 9 in the inlet end portion 13. Delivery behavior control of microfluid with a high degree of flexibility can be achieved.

Abstract: The present invention provides a blood processing apparatus that can introduce a metered quantity of a blood sample into a chamber and does not require an opening linked to the chamber to be closed after the introduction of the blood sample. An introducing chamber, an injection port, and an air port are formed in a rotatable platform of a blood processing apparatus. The injection port links the introducing chamber with the outside of the rotatable platform. A blood sample is introduced from the injection port into the introducing chamber. A blood coagulant is held on the port wall surface of the air port and/or around a portion of the surface of the rotatable platform where the air port is open.
