A pipette core member is used in a pipette for sampling a sample. This pipette core member includes: a pump body including a reservoir communicated with one suction/discharge port of an electroosmotic flow pump, the electroosmotic flow pump and the reservoir being integrally formed; and a capillary connected to the electroosmotic flow pump and communicated with the other suction/discharge port of the electroosmotic flow pump. The capillary is secured to the pump body.

Pipette core member, pipette, and pipette device

Disclosed is a connecting structure of a liquid sending apparatus, including: an electroosmotic flow pump having first and second electrodes upstream and downstream of an electroosmosis material; a flow-path structure which defines with flow-paths for liquid upstream and downstream of the electroosmotic flow pump, which is provided upstream of the electroosmotic flow pump with a ventilation hole communicating with inside and outside of the flow-path, and which is provided with a hydrophobic film which covers the hole and is permeable to bubbles; and a liquid-absorbing body absorbs liquid, which is provided in the flow-path upstream of the electroosmotic flow pump, which comes into abutment against a surface of the electroosmosis material on which the first electrode is provided, and which is formed with a bubble removing passage which passes through the liquid-absorbing body from a hydrophobic film side thereof to the abutment surface against the electrode.
