Abstract
The present invention relates to a pipette device with a pipette channel which extends along a channel axis defining an axial direction and which passes through a channel component arrangement which, at a coupling longitudinal end, has a coupling configuration for the releasable coupling of a pipette tip. The coupling configuration has a locking component with a radially outwardly facing engagement surface arrangement, which is movable between a locking position more radially remote from the channel axis and an unlocking position lying radially closer to the channel axis. The coupling configuration has a sealing component separate from the locking component, and that the actuator drive has a switchable magnetic field source and a reaction component which is movable by the locally changing magnetic field thereof and which is connected to the locking actuator in such a way as to transmit movement.
