Automatic pipettor with a single-row, multi-channel pipetting head
First Claim
1. An automatic pipettor with a single-row, multi-channel pipetting head, with a tip ejector mechanism for removing the pipette tips attached to the pipettes arranged in a row, and a receptacle place for microtitration plates below the pipetting head, comprising:
- said pipetting head being movable in orthogonal direction to the row of pipettes;
said ejector mechanism having a shaft which is oriented in the direction of the row of pipettes and to which a quantity of push-off units equal to the quantity of pipettes are fastened so as to be offset relative to one another at an angle ω
, each of which successively coming into contact with a strip-off unit guided in the direction of the pipettes during rotation of the shaft, displaces it, and strips a pipette tip from a pipette; and
a lifter being arranged below the receptacle place for raising and lowering the microtitration plate in direction of the pipettes.

Abstract
Automatic pipettor with a single-row, multi-channel pipetting head, with tip ejector mechanism by which the pipette tips attached to pipettes arranged in a row are successively removed and which, by means of the movable construction of a lifter arranged below the pipetting head and carrying, e.g., a microtitration plate, can be used in an all-purpose manner for different microtitration plates in the direction of the pipettes and the movability of the pipetting head in a direction orthogonal thereto.
