Abstract (en)
[origin: WO2020114954A2] The invention relates to a liquid-metering device (10) for ballistically discharging a discrete metered amount of metered liquid in a metering volume range of 0.3 nl to 900 nl from a metered-liquid reservoir, said device comprising: - a pipetting-tip receiving device (14), which defines, at least in a metering-ready operating position of the liquid-metering device (10), a receiving space (40) that runs along a virtual receiving axis (A) and is designed to receive a portion of a pipetting tip (42); - a triggering plunger (26), which is movable relative to the pipetting-tip receiving device (14) and can be moved between a standby position in which it is further retracted from the receiving space (40) and a triggering position in which it protrudes further into the receiving space (40); - a movement drive (30), which is coupled to the triggering plunger (26) so as to transmit motion; and - a control device (28) for controlling the operation of the movement drive (30). According to the invention, the liquid-metering device (10) has a first deformation formation (46) and a second deformation formation (48), the first deformation formation (46) and the second deformation formation (48) defining therebetween an axial longitudinal region of the receiving space (40) as a deformation region (44), in which region the first deformation formation (46) and the second deformation formation (48) can be brought closer to one another and moved away from one another, the triggering plunger (26) being located in the deformation region (44) of the receiving space (40) when the triggering plunger is in the triggering position.
