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.
