Problems solved by technology

The operating elements for clamping and releasing the pipette tips on the collar are complex and require a lot of space
The mounting of the pipette tip in a defined engagement position can easily be hampered by manufacturing tolerances or imprecise positioning of the pipette tip on the collar
The annular groove and axial positioning structure limit the use of different pipetting tips

Embodiment Construction

[0101] In this application, the expressions "upper" and "lower", "horizontal" and "vertical" refer to such an orientation of the pipetting head together with the mouth in the vertical direction, at this time, the mouth is arranged in the lower part and the pipetting head The other part is set on the top of the socket.

[0102] When describing the different embodiments, the same reference symbols are used for components with the same designation.

[0103] according to figure 1 and 2 , the pipetting head 1 has a housing 2 formed by front and rear housing shells 3, 4 which are joined together in a vertical plane.

[0104] Eight parallel sockets 5 (plugs) for clamping the pipetting head 6 extend vertically downward from the underside of the pipetting head 1 ( image 3 and 4 ).

[0105] A strip-shaped support plate 7 is arranged on the upper side of the housing 2 . A fixing pin 8 protrudes upward from the support plate 7 .

[0106] according to image 3 , in the pipetting h...

Abstract

The invention relates to a pipetting head having at least one pipette tip for a pipetting device, comprising: a carrier, at least one projection held on the carrier and on which pipette tips are to be clamped, and two elastomer O-rings held on the projection, wherein the two O-rings, the projection and the pipette tip are designed to securely clamp the pipette tip solely by deformation of the two O-rings on the projection, this being brought about by pressing the pipette tip onto the two O-rings.

Description

technical field [0001] The invention relates to a pipetting head for receiving pipetting tips, a pipetting device comprising a pipetting head and a method of pipetting by means of a pipetting head. Background technique [0002] Pipetting devices with pipetting tips for receiving a single pipetting tip or a plurality of pipetting tips simultaneously are used in particular for metering liquids in medical, biological, biochemical and chemical laboratories. [0003] The pipetting head has at least one socket which can be inserted into the insertion opening at the upper end of the pipetting tip. The liquid is taken up into the pipette tip and discharged from the pipetting system through the tip opening at the lower end of the pipette tip. [0004] After use, the pipette tip can be detached from the collar and replaced with a new pipette tip. Contamination during subsequent metering is thereby avoided. Single-use pipette tips made of plastic are economically available. [0005...
