ABSTRACT:
An apparatus for automatic distribution includes a frame (1) having at least a bottom frame portion (1a) and a side frame portion (1b), a tip holding rack (2) and at least one micro plate (4, 5) which are disposed on the bottom frame (1a). A pipette unit (21) is supported by the side frame portion (1b) and adapted to support a plurality of pipettes (43), each of which includes a plunger (41) fitted into a cylinder (35) for movement relative thereto in a vertical direction. In this apparatus the bottom frame portion (1a) is kept stationary and the entire pipette unit (21) can be reciprocally moved in a horizontal direction so that, while the entire pipette unit (21) is being moved reciprocally in the horizontal direction, the pipette unit picks up a plurality of tips (44) from the tip holding rack (2) in order to distribute liquid with respect to a plurality of wells (4a-4h) of the micro plate.
