  • inhomogeneous liquids for example suspensions of beads in an aqueous solution, the density of which is higher than that of water, so that the beads can sink to the bottom. If such an aqueous solution is mixed to homogeneity and then portioned, the proportion of beads in the aqueous phase decreases during portioning until all the beads have sedimented. The number of beads per portion falls accordingly, and portions filled at the beginning of portioning have a higher quantity of beads than those filled later.
  • beads of this type easily accumulate on surfaces in the liquid phase, for example underneath the lid of the storage vessel. This also makes it more difficult to remove portions with the same concentration of beads, particularly in the case of automated processes in which the position of the beads within the transport vessel and their complete transfer are not checked visually.
  • Beads are used as carriers for reagents in many miniaturized systems.
  • the beads in the field of immunodiagnostics, they can be carriers for immobilized antigens to which antibodies to be detected in human samples bind.

  • the storage vessel is preferably steam-tight, watertight and pressure-tight at an internal pressure of up to 2 bar.
  • the nature of the exposed wall sections allows a pressure-closing puncture by at least two hollow needles in such a way that when the hollow needles have been pierced, the puncture points are pressure-tight in such a way that no liquid escapes between the wall sections and the hollow needles when the internal pressure in the capillary is up to 2 bar is present.
  • the base body is preferably rotationally symmetrical to the axis of symmetry of the base body in the longitudinal direction.
  • the reinforcement elements are in particular arranged rotationally symmetrically to the axis of symmetry of the base body and also point-symmetrically to the center point of the axis of symmetry of the base body.
  • the axis of symmetry of the base body preferably extends in the longitudinal direction of the base body.
  • the reinforcement elements are stretched longitudinally, preferably in the longitudinal direction of the storage vessel.
  • the reinforcement elements are preferably so-called ribs, which rest on the outside of the base body.
  • the reinforcement elements are preferably longitudinally stretched ribs with a material thickness which is greater by at least a factor of 2 than a wall thickness or material thickness of the wall sections.
  • the reinforcing elements preferably have a length which is at least 70% of the length of the base body.
  • the reinforcing elements are preferably arranged rotationally symmetrically to the axis of symmetry based on one or more rotations of the capillary around the axis of symmetry by a specific angle, the specific angle being in particular 360° divided by the number of reinforcing elements.
  • the storage vessel is essentially rotationally symmetrical in relation to a rotation of the storage vessel around the axis of symmetry of the storage vessel by a specific angle, which is in particular 360° divided by the number of reinforcing elements.

  • the storage vessel when using four reinforcement elements and thus four different rotational systems about the axis of symmetry of the base body or the axis of symmetry of the storage vessel, it is irrelevant for the purpose of automation which of these four positions the storage vessel occupies.
  • a storage vessel according to the invention is provided in an automation step and this storage vessel is to be fed to a gripping system so that the gripping system is then to grip the storage vessel and also hold it, for example for a step of piercing hollow needles, then a previously occurring sorting step or In the course of the automation, no attention is paid to which of the several positions in which the storage container is supplied or presented to the gripper.
  • wall sections of the base body that are exposed from the outside are also formed between adjacent reinforcement elements, the desired piercing of the hollow needles into these exposed wall sections can take place, so that the wall sections can be dimensioned with regard to their wall thickness in such a way that the wall thickness or the Wall is easy enough to pierce for the hollow needles.
  • the overall mechanical stability of the storage vessel does not have to be brought about solely by dimensioning these wall sections or the wall thickness, but can be ensured by dimensioning the reinforcing elements. The amount of force required to pierce a hollow needle through a wall section can thus be minimized without reducing the overall mechanical stability or robustness of the storage vessel too much. It is then possible to ensure mechanical stability of the storage vessel, in particular with regard to forces occurring during a gripping process by a gripper, by dimensioning the reinforcement elements.
  • the reinforcement elements are located on the outside of the base body, it is also possible to provide the cavity for receiving the liquid without forming additional mechanical elements located in the cavity, such as supporting elements running through the cavity. If such a support element were to be provided within the cavity, such a mechanical element would in turn prevent the flushing liquid from flowing through the cavity and thus reduce the effectiveness of expelling the liquid; so residual volumes of the liquid could remain in the storage vessel, which is undesirable.
  • the base body and the reinforcement elements of the storage vessel are manufactured in one piece by means of an injection molding process. This has the advantage that a homogeneity of the material can be guaranteed for the stability of the storage vessel.
  • the respective exposed wall sections preferably have the same wall thickness. Particularly preferably, the respective exposed wall sections have a respective equal and constant wall thickness in the longitudinal direction of the base body.
  • This has the advantage that a mechanical behavior or a force behavior when one or more hollow needles pierce a corresponding wall section is the same for all wall sections, so that a processing step for puncturing a hollow needle into a wall section is independent of a rotation of the storage vessel about the axis of symmetry of the vessel for certain preferred locations.
  • Such preferred positions result from those positions which are present as described above, taking into account the corresponding angles.
  • the base body and the reinforcement elements of the storage vessel are produced in one piece by means of an injection molding process from plastic, preferably from polyethylene, particularly preferably high-density polyethylene.
  • the plastic is a polyethylene
  • the wall sections are soft enough to pierce one or more hollow needles without a wall section threatening to break or particles being detached from the wall section and introduced into the liquid . This prevents such particles from getting into the liquid and possibly even clogging those hollow needles through which the rinsing liquid is to be expelled from the storage vessel.
  • high-density polyethylene also has the advantage that this plastic is compatible with the requirements of laboratory use for processing biological samples.
  • plastic as high-density polyethylene has the particular advantage that such a plastic has a particularly high tear resistance and stability and can therefore be produced and processed in very thin thicknesses. In this way, a particularly thin or small wall thickness of a wall section or wall sections can then be made, so that the wall sections can be pierced even more easily.
  • polyethylene has the advantage that this plastic is compatible with the requirements of laboratory use for processing biological samples.
  • the base body has no separating seam and no sprue residues on the exposed wall sections for piercing the needles.
  • Such seams or residues are common material artifacts of an injection molding process. Due to the fact that such artefacts are not present on the exposed wall sections, a homogeneity of the material of the wall sections and thus also a mechanical stability of these wall sections is realized. Furthermore, it can be ensured in this way that the insertion of hollow needles into the wall sections can take place with an expenditure of force which is not dependent on whether a wall section has a corresponding material artifact from an injection molding process.
  • the base is preferably curved from the lowest point of the base towards the inner wall of the base body.
  • the base is particularly preferably curved upwards from the lowest point of the base towards the inner wall of the base body.
  • the base body preferably has an essentially constant surface roughness on its inside, in particular an average peak-to-valley height of less than 0.8 Rz, particularly preferably less than 0.4 Rz.
  • a surface roughness selected in the manner described here improves or facilitates the flow of particles or beads on the inside of the base body, so that particles or beads of the liquid are less likely to remain in the storage vessel.
  • the base body has a recess on the underside of the floor.
  • This has the advantage that in this recess there is a position or a location at which material can be sprayed on in an injection molding process or can be introduced into an injection molding tool. If a material artifact then occurs in this recess, such as a sprue residue, then this material artifact does not protrude beyond the underside of the base, but rather remains in the recess.
  • the wall thickness of the exposed wall sections is preferably more than 0.15 mm, preferably more than 0.2 mm. By choosing the wall thickness in the manner described here, a minimum stability of the wall sections for the piercing of the needles is achieved guaranteed.
  • the wall thickness of the reinforcement elements is preferably at least 0.5 mm, more preferably at least 0.8 mm, most preferably at least 1 mm.
  • the respective wall sections preferably have the same wall width between two reinforcing elements delimiting a respective wall section.
  • the storage vessel has on its upper side a border surrounding the opening of the base body, which is spaced apart from an outer edge of the opening by a distance.
  • the spacing is preferably at least 0.01 mm, particularly preferably 0.05 mm.
  • the border is preferably at least 0.2 mm high.
  • the closure of the storage vessel is a film which is applied or fastened to the border by means of a melting process.
  • the border has the advantage that it can serve as a base for the film, although it is possible for the shape of the edge to change when the film melts. If the edge becomes too wide during the melting process, this can lead to the edge widening in the direction of the axis of symmetry of the storage vessel and expanding in this direction over the outer edge of the opening of the base body, which can form a so-called undercut, which forming the overhanging material of the rim and overlying the foil over the outer edge of the opening. In such an undercut, volumes of liquid, but also particles or beads of the liquid, can then be held back during the flushing process.
  • the fact that the outer edge is preferably at a distance from the opening ensures that such an undercut does not form even during a melting process.
  • the liquid is preferably an inhomogeneous liquid phase, preferably an aqueous solution comprising beads.
  • the liquid is a homogeneous liquid phase, preferably comprising a biological or chemical agent in aqueous solution or liquid sample, more preferably a blood sample, most preferably serum.
  • the reinforcing elements preferably have a material thickness which is at least twice as great as the wall thickness of the exposed wall sections. This ensures a minimum mechanical stability of the storage vessel.
  • the storage elements preferably have a material thickness which is at most four times greater than the wall thickness of the exposed wall sections. This is advantageous in injection molding processes for jointly producing the base body and the reinforcing elements in one piece, since if the differences in the material thicknesses are too large, the plastic material in the mold or in the injection molding tool cannot otherwise flow reliably for all volume areas within the tool or within the mold can.
  • the liquid is an inhomogeneous liquid phase, preferably an aqueous solution comprising solids such as particles or beads.
