This ensures that the syringe and pipette can be connected to each other by a purely axial relative movement and separated from each other by an actuation of the fastening devices.
  • the user to disconnect the syringe from the pipette, the user must press inwardly the actuating arms of the syringe gripping levers.
  • the gripping arms release the syringe flange and press the release cams of the syringe gripping lever, the actuating arms of the piston gripping levers so that they release the syringe plunger.
  • Preloaded coil springs of a flange stopper push the axial opening of the repeater pipette to expel the syringe.
  • both syringe grippers must be operated simultaneously with two fingers.
  • a pipette is known in which the syringe by releasing only a single trigger from the pipette is solvable.
  • US 5620 660 A1 is provided, the syringe gripping levers on the actuating arms inwardly projecting release lever.

  • a releasably arranged in the pipette housing trigger is coupled to the transmission element to move the displacement of the trigger, the transmission element in the guide.
  • the gripping means comprise radially deliverable Zylindergreifhebel and piston gripping levers, which are normally in gripping position and can be brought by operating the actuator in a release position in which the flange and the piston head of a syringe are released for removal or recording.
  • the actuator has on the pipette housing a central, operable from the outside actuating element, the movement of which is transmitted on actuation on the one hand via a first power transmission train on the Zylindergreifhebel and on the other hand via a second power train on the piston gripping lever.

  • the relevant versions of the DE 199 17 907 A1 are also incorporated by reference into the present application.
  • the means for displacing the Abwerfschiebers from the waiting position to the release position and back can be configured differently.
  • the means for displacing the Abwerfschiebers are coupled to the Kolbenstell Surpriseen to shift the Abwerfschieber from the waiting position to the release position and from the release position to the waiting position.
  • the displacement of the Abwerfschiebers is effected, for example, by actuating the elevator member, wherein the displacement direction of the elevator member determines the displacement direction of the Abwerfschiebers.

This ensures that the syringe is not released until the contents are completely or almost completely dispensed.
  • the displacement of the Abwerfschiebers in the release position limited to a residual stroke of the receiving body for the delivery of a residual amount of the liquid from the syringe, which is less than a predetermined dosage.
  • the pipette has means for automatically overriding the displaceability of the receiving body by means of the actuator at the entrance of the receiving body in the end portion of its displacement range, in which the available residual stroke falls below a predetermined Dosierhub, which is required to deliver a predetermined dosage.
  • the automatic override of the actuator the user notices that the predetermined dosage is no longer available. Accidental dosing too small a residual amount is thereby effectively prevented.
  • the rest quantity can be given in different ways.
  • the receiving body in the end portion of its displacement region by actuation of the elevator member is displaced.
  • the user can cause the delivery of the residual amount by targeted actuation of the elevator organ.

  • liquid is absorbed by displacement of the elevator organ into the syringe, whereby the receiving body is also moved beyond the end portion.
  • the Abwerfschieber be relocated from the release position to the waiting position due to the coupling of the means for displacing the Abwerfschiebers with the piston adjusting devices.

  • This ramp element is formed for example by a cam with a ramp-like flank.
  • the actuator can actuate the Abwerfschieber directly or indirectly.
  • the actuating member is connected to a diaphragm whose end face is associated with one end of the Abwerfschiebers to push the Abwerfschieber from the release position against the release lever.
  • the diaphragm can serve the cover of a housing opening, through which the actuator is led out of the pipette housing to the outside.
  • a sprung abutment 8 is arranged, against which the upper side of the syringe flange 4 can be pressed.
  • the abutment 8 has sensors 8.1. for scanning a coding at the top of the syringe flange 4.
  • the syringe gripping levers 14 are arranged with a gripping arm 17 below the pivot axes 15.
  • An actuating arm 18 of the syringe gripping lever 14 is located above the pivot axes 15th
  • torsion springs are arranged, which bias the piston gripping lever 22 in the direction of a position in which they attack the piston collar 23.
  • the outer side of the actuating arm of the piston gripper lever 22 is shaped so that they are in this locking position in the pivoting range of Entriegelungsnocken on the inside of the syringe gripping lever 14.
  • the correct alignment of the piston gripper lever 22 on the syringe gripping lever 14 is ensured by the guidance of an elevator member 24 in an axial slot 25 of the pipette housing 2 ( Fig. 1 ).
  • the release levers 26 are connected to the upper ends of the actuating arms 18 and inclined at an acute angle to the axis of the syringe plunger 11.
  • the piston adjusting devices 28 include a threaded spindle 31 (alternatively a rack), which is also firmly connected to the receiving body 9.

  • the strut 47 has on top two cams 50, each having a ramp at the top.
  • the housing 30 connected to the receiving body 9 is provided with a tongue 51 which extends parallel to the piston receptacle ( Fig. 5 ).
  • the tongue 30 has at the bottom recesses 52 which are complementary to the cam 50 formed on the strut 47.
  • the cams 50 can engage in the recesses 52.
  • the dosing amount is set by means of the knob 33.

  • Liquid can be absorbed into the syringe 5 by displacing the elevator member 24 upwards. By means of the rotary knob 33, a dosage is set. By pressing the actuator 35, the syringe plunger 11 is down moved and delivered the desired amount of liquid. When the syringe 5 is almost deflated, so that only a residual amount is located therein, the leaf spring 42 keeps the pawl 41 from falling into the threaded spindle 31 from. The user can then deliver by pushing the elevator member 24 down the remaining amount. In this case, the driver 30 pushes the Abwerfschieber 44 so that the ramps 53 run over the cam and lift the upper end of Abwerfschiebers 44 ( Fig. 8 ).
  • the syringe 5 can be emptied by a single or multiple actuation of the actuator 35, wherein the aperture 40 does not come into contact with the upper end of Abwerfschiebers 44, since this is not in the range of movement of the aperture 40. Only after delivery of the remaining amount, the syringe 5 can be solved in the manner described by the pipette 1.
  • the driver 30 displaces the Abwerfschieber 44, so that the ramps 53 run over the cam and the upper end of the Abwerfschiebers 44 enters the range of movement of the aperture 40.
  • the Abwerfschieber 44 can create resiliently against the inside of the aperture 40.
  • the upper end of the Abwerfschiebers 44 enter the range of movement of the aperture 40. Possibly. this is supported by pivoting the lever arm 54 upwards, so that the control cam 57 hits against the threaded spindle 31 facing side of the Abwerfschiebers 44 supported. Further actuation of the actuating button 35 causes a displacement of the Abwerfschiebers 44, so that the release lever 26 are actuated and syringe 5 is dropped.
  • liquid can be dispensed in the manner already described and the syringe 5 can be discarded.
