The invention relates to a metering apparatus (10), in particular a pipetting machine, comprising a pipetting device (12) that can be moved in three directions (X, Y, Z) orthogonal to each other and that has at least one pipetting channel (16) to which a pipetting tip (18) is or can be detachably attached in order to aspirate sample liquid from a sample container (34, 36) associated with the metering apparatus (10) or to dispense sample liquid into a sample container (34, 36), wherein the at least one pipetting channel (16) is designed in such a way that a pipetting tip (18) detachably attached to the pipetting channel can be removed from the pipetting channel (16), preferably can be automatically removed, and a disposal container (40), which is arranged on the metering apparatus (10) and in which used pipetting tips (18) can be accommodated after being removed from a relevant pipetting channel (16). According to the invention, the disposal container (40) is arranged on the metering apparatus (10) in such a way that the disposal container can be moved in at least one direction relative to the at least one sample container (34, 36), wherein the pipetting device (12) and the disposal container (40) can be moved in the same direction (X) at least temporarily, preferably can be moved synchronously. |
