摘要： The invention relates to a pipetting device (10) comprising a coupling formation (16) for detachably coupling a pipetting tip (70) to same, and comprising a pipetting channel (12) for changing a pressure in a pipetting tip (70) coupled to the coupling formation (16), said channel extending along a channel path (K) and passing through the coupling formation (16), wherein the coupling formation (16) is formed in such a way that a pipetting tip (70) can be pushed on and taken off said formation along a coupling path (C) which is preferably collinear with the channel path (K). The coupling formation (16) has a coupling deformation assembly having a deformation component (18) and surrounding the pipetting channel (12), which deformation component can be deformed between a locking position and a release position for locking and unlocking a pipetting tip (70) on the coupling formation (16), wherein a radially outer lateral surface section (18c) of a bulge section (18c) of the deformation component (18) - which bulge section is positioned between longitudinal ends (18a, 8b) of the deformation component (18) provided along the coupling path (C) at a distance from one another - is positioned, in the locking position, radially further outwards in relation to the coupling path (C) than in the release position. According to the invention, at least in the locking position, a wall thickness (w) of the bulge section (18c) of the deformation component (18) is smaller than the dimension of the deformation component (18) along the coupling path (C).

摘要： The invention relates to a pipetting device (10) for pipetting dosing liquids (32), comprising a pipetting channel (12) extending along a channel path (K), in which a piston (14) designed as a solid body is movably accommodated along the channel path (K) in order to alter, by way of movement along the channel path (K), the pressure of a working gas (34) that wets the piston (14) on a dosing side (14a) facing the dosing liquid. The pipetting device (10) further comprises a motion drive (20) for the piston (14), by means of which the piston (14) can be driven to a movement along the channel path (K). The pipetting device (10) also comprises a control unit (24) for controlling the motion drive (20). According to the invention, for pipetting a predetermined single dosing volume (36) of less than 5 µl, the control unit (24) is configured to operate the motion drive (20) such that the piston (14) is moved in a pipetting direction (P), and in doing so, the dosing-side end surface (14a) thereof sweeps across a pipetting volume, which is no less than 1.4 times larger than the single dosing volume (36), and subsequently, the piston (14) is moved in a counter pipetting direction (G) that is counter to the pipetting direction (P). In doing so, the dosing-side end surface (14a) thereof sweeps across a counter pipetting volume, wherein between the start of the control signal of the control unit (24) for driving the piston (14) in a pipetting direction (P), and the end of the control signal for driving the piston (14) in a counter pipetting direction (G), no more than 50 ms (milliseconds), preferably no more than 30 ms elapse.

摘要： The invention relates to a linear motor, comprising at least one stator device (14) having a plurality of permanent magnets (18, 18-1, 18-2) of different polarity and having at least one carrier rail (24), and at least one rotor device (12) having at least three electrical coils (44) and having at least one supporting means (26) that can be supported or is supported on the carrier rail (24) of the stator device (14), wherein the rotor device (12) and the stator device (14) can be moved to and fro relative to each other by interaction of the magnetic fields of the permanent magnets (18, 18-1, 18-2) with the magnetic fields of the coils (44), through which current flows if required, along a movement direction (FR) defined by the carrier rail (24), wherein the stator device (14) is formed from at least one stator module (16-1, 16-2), wherein the stator module (16-1, 16-2) is configured in such a manner that a stator device (16) having two or more stator modules (16-1, 16-2) arranged one after the other can be formed, and wherein at least one measurement track (40, 40-1, 40-2, 40-3) is provided on the stator module (16-1, 16-2), which measurement track can be scanned by a sensor unit (52-1, 52-2) of the rotor device (12) and runs substantially parallel to the movement direction (FR). According to the invention, at least two sensor units (52-1, 52-2) are provided on the rotor device (12), which sensor units scan the measurement track (40, 40-1, 40-2, 40-3) and are arranged at a distance (SA) from one another in the movement direction (FR) of the rotor device (12) in such a manner that, if the rotor device (12) is arranged at a connection point (64, L) between two stator modules (16-1, 16-2), the respective measurement tracks (40, 40-1, 40-2, 40-3) on the adjacent stator modules can be scanned respectively by one of the two sensor units (52-1, 2-2).

摘要： Eine Pipettiervorrichtung (10) zum Pipettieren von Dosierflüssigkeiten (32) hat einen sich längs einer Kanalbahn (K) erstreckenden Pipettierkanal (12), in welchem ein als Festkörper ausgebildeter Kolben (14) längs der Kanalbahn (K) beweglich aufgenommen ist, um durch Bewegung längs der Kanalbahn (K) den Druck eines Arbeitsgases (34) zu verändern, welches den Kolben (14) auf einer der Dosierflüssigkeit zugewandten Dosierseite (14a) benetzt. Die Pipettiervorrichtung (10) umfasst weiter einen Bewegungsantrieb (20) für den Kolben (14), mit welchem der Kolben (14) zu einer Bewegung längs der Kanalbahn (K) antreibbar ist. Ebenso umfasst die Pipettiervorrichtung (10) eine Steuereinrichtung (24) zur Steuerung des Bewegungsantriebs (20) aufweist. Erfindungsgemäß ist vorgesehen, dass die Steuereinrichtung (24) dazu ausgebildet ist, zur Pipettierung eines vorbestimmten Einzel-Dosiervolumens (36) von weniger als 5 µl den Bewegungsantrieb (20) derart zu betreiben, dass der Kolben (14) in Pipettierrichtung (P) bewegt wird und dabei seine dosierseitige Endfläche (14a) ein Pipettiervolumen überstreicht, welches um nicht weniger als das 1,4-fache größer als das Einzel-Dosiervolumen (36) ist, und dass der Kolben (14) anschließend in einer der Pipettierrichtung (P) entgegengesetzten Gegenpipettierrichtung (G) bewegt wird und dabei seine dosierseitige Endfläche (14a) ein Gegenpipettiervolumen überstreicht, wobei zwischen dem Beginn des Steuersignals der Steuereinrichtung (24) zum Antrieb des Kolbens (14) in Pipettierrichtung (P) und dem Ende des Steuersignals zum Antrieb des Kolbens (14) in Gegenpipettierrichtung (G) nicht mehr als 50 ms, vorzugsweise nicht mehr als 30 ms verstreichen.
