LIQUID TRANSFER DEVICE
First Claim
1. A liquid transfer device comprising:
- a pipette forming an interior space extending in an axial direction and having first and second ends, the first end forming an opening and the second end forming an enclosed variable volume, whereby variation of the volume causes change of pressure, which selectively induces a suction force or a releasing force in the pipette, the pipette further comprising at least one fixing section;
an analysis container forming a plurality of receptacles which is retained by a slab, the analysis container comprising a lock section;
cover means comprising a cover film that covers a surface of the slab to seal the analysis container; and
movement control means comprising a manipulator and a tray, the tray forming a cavity receiving the analysis container therein and a retention section engageable with the lock section to secure the analysis container to the tray.

Abstract
A liquid transfer device is provided for biochemical assay, including a pipette forming an interior space extending in an axial direction and having first and second ends. The first end forms an opening and the second end forms an enclosed variable volume, whereby variation of the volume causes a change of pressure to selectively induce a suction force and a releasing force in the pipette. An analysis container includes a plurality of receptacles retained by a slab. A film covers the slab to seal the container. A movement control device includes a manipulator that releasably holds the pipette and a tray that forms a cavity for receiving and retaining the container. The pipette and the tray are movable with respect to each other in order to fill/draw test agent into/out of the receptacles.

- 12. A pipette adapted to use in a liquid transfer device, comprising a hollow member extending in an axial direction and having first and second ends in the axial direction, the first end forming an opening, the second end forming an enclosed variable volume, whereby the variation of the volume causes change of pressure to selectively induce a suction force or a releasing force in the pipette, the pipette comprising at least one fixing section.
- 16. A container for use in a liquid transfer device comprising a plurality of receptacles retained by a slab, the container further comprising a lock section, and cover means comprising a film covering a surface of the slab.
