Definitions

  • the invention relates to a spacer for holding stacked plate-shaped and essentially rectangular pipette tip carriers with holes and pipette tips inserted therein at a distance from one another.
  • Pipette tips are used in particular in biological, chemical, biochemical, medical or forensic laboratories in order to dispense small amounts of liquid using pipetting devices.
  • the pipetting devices are manual pipettes, automatic dosing stations or laboratory machines (workstations).
  • the pipetting devices have one or more channels to accommodate a single pipette tip or a plurality of pipette tips in a row or in a matrix arrangement.
  • the pipetting devices have projections or blind bores onto or into which the upper ends of the pipette tips can be clamped or clamped.
  • the distances between the channels are usually based on the distances between the wells of standardized microplates according to the ANSI SBS 1 to 4 standard; American National Standard; American National Standard Institute, voted 2006.
  • the disposable plastic pipette tips are used. These must be made available in large quantities to carry out investigations.
  • Plate-shaped and essentially rectangular pipette tip carriers with a large number of holes in a matrix arrangement are used to provide pipette tips.
  • the pipette tips are inserted into the holes from above, whereby they do not fall through due to a diameter that widens upwards or a collar.
  • the pipette tip carrier is placed on the edge of a top opening of a frame or box so that the Pipette tips engage in the top opening.
  • one or more pipette tips can be removed from the pipette tip carrier by pressing onto the attachments or pressing into the blind holes. After use, the pipette tips are released from the pipetting device into a container by means of an ejection device in order to be disposed of.
  • the pipette tip carrier with a peripheral side wall that protrudes downward and is supported outside the holes on a pipette tip carrier arranged underneath (cf. EP 2 784 076 A1 ). It is also known to arrange a frame-shaped spacer between stacked pipette tip carriers, which is supported with its upper edge outside the holes on the underside of a pipette tip carrier arranged higher and with its lower edge outside the holes on the upper side of a pipette tip carrier arranged below. In addition, it is known to connect the spacer to the upper pipette tip carrier by means of snap connections (cf. EP 2 839 880 A1 ).
  • the EP 2 848 308 B1 describes a spacer comprising centering spring elements arranged on the inside of the longitudinal and transverse sides of the side wall, each comprising a resilient part spaced from the inside of the side wall to which the centering spring element is fixed.
  • the resilient part can exert a spring effect between the inside of the respective side wall and a part of a pipette tip carrier to be stacked, which part is received in a central opening of the spacer.
  • the centering spring elements are designed in such a way that they act on a pipette tip carrier on which the spacer rests and minimize the horizontal play between the pipette tip carrier and the spacer without locking the pipette tip carrier with the spacer.
  • centering spring elements arranged on the inside of the longitudinal and transverse sides of the side wall. In the exemplary embodiment, there are two centering spring elements on each longitudinal and transverse side, ie a total of eight.
  • the object of the invention is to provide a spacer for plate-shaped pipette tip carriers stacked on top of one another, which enables improved centering and stabilization of a carrier stack with reduced use of materials and production costs.
  • the spacer according to the invention for holding plate-shaped and essentially rectangular pipette tip carriers stacked on top of one another at a distance from one another comprises a peripheral side wall which forms an essentially rectangular frame with two longitudinal and two transverse sides, which has a horizontal standing surface on a lower edge for support on a top side of a pipette tip carrier, on an upper edge a horizontal support surface for supporting a further pipette tip carrier on the underside, on corners between adjacent longitudinal and transverse sides from the upper edge vertically upwards protruding pins and on the side wall bending elements, wherein the bending elements in an acute angle to the adjacent longitudinal and transverse sides extending direction are bendable.
  • centering of the spacer in the stack is achieved by the bending elements at the corners of the side wall, which can be bent in a direction running at an acute angle to the adjacent longitudinal and transverse sides.
  • the bending elements can be bent or deflected by contours of a further spacer introduced from below into the circumferential side wall and/or a pipette tip carrier supported on the support surface of the introduced further spacer, or rest against them without play.
  • the bending of the bending element can be outwards or inwards with respect to the frame of the spacer.
  • a slight bending or deflection or play-free contact of the bending elements results in the spacer being centered on the contours of the further spacer introduced from below and/or of a pipette tip carrier supported on the further spacer.
  • the forces acting due to the centering between the bending elements and the contours of the spacer or pipette tip carrier can be kept so low that the spacer from the further spacer and the supported thereon pipette tip carrier can be deducted without the further spacer or the pipette tip carrier is taken here.
  • This can be achieved in particular by designing the bending elements to be particularly flexible and/or by manufacturing the bending elements and the contours of the spacer and/or the pipette tip carrier precisely or with low tolerances.
  • the spacer can be produced in a material-saving manner because the bending elements only have to be present at the corners of the spacer, with formation at only two diametrically opposite corners being sufficient. Furthermore, the bending elements can be formed within the peripheral side wall and no additional spring elements applied to the inner sides of the side wall are required for this. As a result, the outlay for tools for injection molding the spacer and the outlay for producing the spacer as a whole can also be reduced. If the centering is carried out by placing the bending elements on the contours of a further spacer of the same construction, it may be sufficient to manufacture the spacer with the relevant contours and bending elements with correspondingly low tolerances and the pipette tip carrier with larger tolerances, which further reduces the cost of production.
  • the bending elements can be bent by pegs inserted from below of a further spacer of the same construction and/or by corners or radii at the corners between adjacent longitudinal and transverse sides of a pipette tip carrier supported on the support surface of the further spacer.
  • the pegs of the further spacer and/or the corners or radii at the corners of the pipette tip carrier carrying the further spacer form the contours through which the bending elements can be bent or deflected or on which the bending elements rest without being bent or deflected.
  • the pin of the other spacer and / or corners or Radii of a pipette tip carrier supported thereon are arranged at the corners of the spacer placed thereon, so that they are particularly suitable for centering the spacer.
  • the pipette tip carrier which is used to center the spacer, has a rectangular plate-shaped body, holes extending vertically from the top to the bottom of the body for receiving pipette tips, an edge surrounding the body with an upper contact surface arranged lower than the top of the body Placing a spacer with a base at the bottom and a lower contact surface on the downward-facing side for placement on a support surface at the top of another spacer and above the peripheral edge corners of the plate-shaped base body.
  • the corners of the plate-shaped base body preferably have radii.
  • the pins are cylindrical and/or have a conical or convex end. This makes it easier to place the spacer on another spacer with the bending elements in contact with the pin.
  • the direction in which the flexures are bendable is oriented diagonally to the corners of the frame. Accordingly, this direction extends along a straight line connecting two non-adjacent corners of the rectangular frame.
  • the direction in which the bending elements can be bent can be aligned at different or the same acute angles to the respectively adjacent longitudinal and transverse sides.
  • the spacer has the bending elements at at least two diametrically opposite corners, preferably at all four corners. Centering, which prevents displacement in the direction of the longitudinal and transverse sides of the spacer, can already be achieved by bending elements that are only arranged at two diametrically opposite corners. Preferably, flexures are located at all four corners to form particularly stable stacks.
  • the peripheral side wall is connected at the top to an inwardly projecting peripheral flange which has the support surface for supporting a further pipette tip carrier on its upper side.
  • the all-round flange increases the stability of the spacer.
  • the pins project upwards from the top of the flange.
  • the bending elements have vertical cylindrical shells at a distance from the side wall at the corners, which are connected at their upper ends to the spacer.
  • the cylindrical shells can be designed in such a way that they are supported on the radii of a pipette tip carrier, which is supported on a further spacer inserted with the pegs into the peripheral side wall in order to bring about centering.
  • the cylindrical shells with concavely curved inner sides lie against the radii of the pipette tip carrier.
  • the cylindrical shells are connected in one piece to the spacer.
  • the bending elements each have at least one vertical slot at a corner of the side wall, starting from the lower edge of the side wall and ending above the lower edge in the side wall. Flexures are formed in the sidewall by the slots. The slots allow the adjacent portions of the sidewall to be easily flexed radially outward by pins inserted from below. This Execution type is particularly material-saving, since the bending elements are integrated into the side wall and material is saved by the slots.
  • the vertical slots at each corner extend from the inside to the outside of the side wall.
  • the vertical slots do not each extend from the inside to the outside, thereby forming somewhat stiffer flexures.
  • the slots extend from the inside to just short of the outside of the side wall or from the outside to just short of the inside of the side wall.
  • the areas of the side wall at the corners between two adjacent vertical slots are particularly flexible and can rest against the inserted pins, further reducing the force.
  • the two vertical slots are arranged symmetrically with respect to the respective corner. This achieves an even application of force at the corners.
  • only one vertical slot is arranged at each corner.
  • horizontal slits are arranged at the corners in the side wall, each extending from the corner into the two adjacent areas of the side wall, and the vertical slits each open at the top into the horizontal slit at the same corner. through the horizontal slits further increases the flexural softness of the flexures formed by the vertical slits and further reduces the forces between over-stacked spacers.
  • the side wall has an inner radius at the corners on the inside and/or an outer radius on the outside.
  • the bending softness of the bending elements is further increased by the radius.
  • the radius on the inside of the side wall makes it easier to insert the pins of another spacer into the peripheral side wall of the spacer.
  • the side wall at the corners on the inside has a radius which corresponds to or exceeds the radius of the pins.
  • the subject of the invention is a transport unit for pipette tips comprising a pipette tip box, a pipette tip carrier fitted to the pipette tip box and provided with pipette tips and at least one arrangement of a spacer according to one of Claims 1 to 15 or one of the above embodiments and one placed on the pipette tip carrier Spacers attached and provided with pipette tips, further pipette tip carrier.
  • the transport unit is formed by placing one or more arrangements of a spacer with a pipette tip carrier fitted thereon, which is provided with pipette tip carriers, on a pipette tip box and a pipette tip carrier fitted thereon, which is provided with pipette tips.
  • the at least one spacer keeps the pipette tips at a distance from one another in pipette tip carriers arranged one above the other, so that they can engage in one another without jamming one another. This way will achieves a space-saving and compact transport unit.
  • the transport unit can also be used to store the pipette tips.
  • a cover is placed on a pipette tip carrier or on a spacer placed on a pipette tip carrier.
  • the transport unit is covered at the top by the lid and protected from contamination.
