[0043] FIG. 2 shows a schematic sectional view of the embodiment shown in FIG. 1, wherein the support element receives the sample container receptacle and, as a result, a plurality of sample containers are lifted; and

[0044] FIG. 3 shows a schematic perspective view of a second preferred embodiment of the sample container handling system according to the invention, wherein the support element receives the sample container receptacle and, as a result, a plurality of sample containers are lifted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0045] FIGS. 1 and 2 show a sample container handling system 1 according to a first preferred embodiment. The sample container handling system 1 has a sample container receptacle 2 for receiving a plurality of sample containers 3. The sample containers 3 are each configured to receive or to contain a sample P. The sample P can comprise a chemical such as, for example, an acid. Each of the sample containers 3 can be of an elongate configuration and/or be a test tube.

[0046] The sample container receptacle 2 has a plurality of holding structures 4, 5 which are each configured to hold a respective sample container 3. The holding structures 4,5 are disposed about a rotation axis 6. The holding structures 4, 5 in the embodiment illustrated in FIGS. 1 and 2 have three groups of holding structures 4, 5, specifically first holding structures 4, 5 which are disposed on a first imaginary (outer) ring A that runs about the rotation axis 6, second holding structures 4, 5 which are disposed on a second imaginary (central)ring B that runs about the rotation axis 6, and third holding structures 4, 5 which are disposed on a third imaginary (inner) ring C that runs about the rotation axis 6. The imaginary rings A, B, C thus have a common center, specifically the rotation axis 6. The rings A, B, C are configured so as to be circular, wherein the radius of the third imaginary ring C is smaller than that of the second imaginary ring B, and the radius of the second imaginary ring B is smaller than that of the first imaginary ring A. In other embodiments, the rings A, B, C can each also have another shape such as, for example, an elliptic, polygonal, rectangular or square shape. The sample containers 3 by way of the holding structures 4, 5 can thus be disposed in a ring arrangement corresponding to the imaginary rings A, B, C. As a result, the sample containers 3 can be disposed so as to be very close together. In other embodiments, it is also conceivable for the holding structures 4, 5 to be disposed only according to one or two of the imaginary rings A, B, C.

[0047] The sample container receptacle 2 furthermore has a base 7. The base 7 in turn has a support region 8 on which the sample containers 3 held by way of the holding structures 4, 5 can be supported. Thus, each of the sample containers 3 by way of the respective base thereof, the latter for example being at least partially configured so as to be convex, is supported on the support region 8. Each of the holding structures 4, 5 can be at least partially configured in the support region 8 of the base 7. This means that each of the holding structures 4, 5 has a respective holding part 5 which is configured in the support region 8 of the base 7. The holding part 5 can be configured as a clearance that can receive the respective sample container 3, in particular the base of the latter, for example. The holding part 5 of each holding structure is preferably configured to prevent a movement of the respective sample container 3 in a direction transverse or perpendicular to the rotation axis 6, but to permit a movement in a direction away from the holding part 5 and parallel to the rotation axis 6, for example. The holding part 5, configured in the base 7, can not only serve for holding but also for supporting the respective sample container 3. The holding parts 5 of the holding structures 4, 5 can thus form the support region 8 of the base 7.

[0048] However, the invention is not limited to each of the holding structures 4,5 by way of the respective holding part 5 being at least partially configured in the support region 8 of the base 7. In other embodiments it can also be provided that the holding structures are each not configured in the support region 8. The support region 8 in this instance serves exclusively for supporting and thus not for (further)holding of the respective sample container 3. In this instance it can be provided, for example, that the support region 8 is configured so as to be planar or flat, thus extending in only one plane, for example.

[0049] The sample container receptacle 2 can furthermore have a holding element 9 which is spaced apart or distal from the base 7 and in which each of the holding structures 4,5 is at least partially configured. With reference to FIGS. 1 and 2, this means that each of the holding structures 4,5 has a respective holding part 4 which is configured in the holding element 9. The holding part 4 of each holding structure is preferably configured to prevent a movement of the respective sample container 3 in a direction transverse or perpendicular to the rotation axis 6, but to permit a movement in a direction away from the base 7 and parallel to the rotation axis 6, for example. As can be seen in FIGS. 1 and 2, each holding part 4 can be configured as a through opening, for example, through which the respective sample container 3 is able to be guided and is thus held by the latter. The through openings 4 preferably extend along the vertical and/or parallel to the rotation axis 6. A sample container 3 can thus be guided through a respective through opening 4 or be inserted into the latter, so as to subsequently be supported on the support region 8 and preferably be held by the holding part 5. Each of the holding structures 4, 5, by way of the respective holding part 4 thereof and/or the respective holding part 5 thereof, is preferably configured to hold a sample container 3 so as to be substantially parallel to the rotation axis 6.

[0050] The holding element 9 is not limited to a specific design embodiment. As is illustrated in FIGS. 1 and 2, the holding element 9 can be configured in the form of a disk, for example. The holding element 9 preferably has a side that faces the support region 8 and a side that faces away from the support region 8, wherein the through openings 4 preferably each extend from the former side to the latter side. The holding element 9 can be, for example, a perforated disk which is formed by the plurality of through openings 4.

[0051] The base 7 furthermore has a side 10 that faces away from the support region 8. Moreover, the base 7 has a plurality of through openings 11 which each extend from the side 10 to the support region 8. The through openings 11 in the embodiment illustrated in FIGS. 1 and 2 are disposed so as to correspond to the imaginary rings A, B, C. This means that, when viewed in a plan view of the system 1, the holding structures 4, 5 are at least partially congruent with the through openings 11. In other words, each through opening 11 is preferably disposed so as to be in alignment with a respective holding structure 4, 5, thus for example a respective holding part 4 and/or holding part. It is preferable for a respective through opening 11 to be provided for each holding structure 4,5. However, it can also be provided that a respective through opening 11 is provided for each group of holding structures 4, 5. Each of the through openings 11 extends in such a manner that there can be access to a corresponding sample container 3 which is supported on the support region 8 by way of the respective through opening 11. It can thus be provided, for example, that each through opening 11 opens into a respective or corresponding clearance 5.

[0052] The through openings 11 in the embodiment illustrated in FIGS. 1 and 2 have three (groups of) through openings 11, specifically one or more first through openings 11 which are disposed so as to correspond to the first imaginary ring A, one or more second through openings 11 which are disposed so as to correspond to the second imaginary ring B, and one or more third through openings 11 which are disposed so as to correspond to the third imaginary ring C. In other embodiments it can however also be provided that the through openings 11 are disposed only according to the first imaginary ring A and/or second imaginary ring B.

[0053] The sample container receptacle 2 can furthermore have a preferably rod-shaped handling structure 12 (for example in the form of a guide rod) by way of which the sample container receptacle 2 can be handled, for example for the latter to be inserted into a pressure container or a reaction chamber of the pressure container or to be retrieved from the latter. As illustrated in FIGS. 1 and 2, the handling structure 12 can for example extend so as to be parallel to the rotation axis 6 and/or be congruent with the rotation axis 6. This means that, by rotating the handling structure 12 about the axis thereof, the sample container receptacle 2 can be rotated about the rotation axis 6. The handling structure 12 preferably has a fastening region 13 (for example in the form of a flange region) by way of which the sample container receptacle 2 can be fastened in a pressure container or a reaction chamber of the pressure container, for example by way of a suspension mechanism. The holding element 9 is preferably held by the handling structure 12 or fastened to the latter. When one or more sample containers 3 are held by way of the handling structures 4, 5, said sample containers 3 preferably extend parallel to the handling structure 12.

[0054] The sample container handling system 1 furthermore has a support element 20 which is connectable to the base 7 of the sample container receptacle 2 in such a manner so as to receive the sample container receptacle 2. In order for the sample container receptacle 2 to be reliably received by the support element 20, the latter can be configured in the form of a bowl, i.e. be a bowl element, for example. It is preferable for the support element 20 to have a shape which at least partially corresponds or is complementary to the base 7. As can be seen in FIGS. 1 and 2, the support element 20 can have a base 21 and at least one lateral wall 22 which extends away from the base 21. The base 21 is configured such that the base 7 of the sample container receptacle 2 by way of the side to thereof can be supported on the base 21. To this end, the base 21 preferably has a front side or supporting side 23 on which the side 10 can be supported. The base 21 furthermore has a rear side 24 which faces away from the supporting side 23 and by way of which the base 21, and thus the support element 20, can be supported on a surface, for example of a table, or be fastened to said surface.

[0055] The support element 20 has a plurality of protrusions 25, 26, 27 which are each provided for lifting a sample container 3. In other embodiments, the support element 20 can also have more or fewer protrusions, for example only one protrusion. The latter in this instance can be provided for lifting one or a plurality of sample containers 3. Each protrusion is configured to lift a single sample container 3 or a plurality of sample containers 3. In the embodiment illustrated in FIGS. 1 and 2, a first protrusion 25 is provided for lifting a sample container 3 which is disposed according to the first imaginary ring A. Furthermore, the protrusions in this embodiment have: a second protrusion 26 for lifting a sample container 3 which is disposed according to the second imaginary ring B and a third protrusion 27 for lifting a sample container 3 which is disposed according to the third imaginary ring C.

[0056] The protrusions 25, 26, 27 can be provided so as to be releasable. This can for example be implemented in that one or more of the protrusions 25, 26, 27 are plugged and/or screwed into the base 21. In other embodiments, the protrusions 25, 26, 27 can be configured so as to be integral to the base 21. The protrusions 25, 26, 27 are each not limited to a specific configuration. It is preferable for the protrusions 25, 26, 27 to each be configured as a column and/or circular in cross section, thus to have the shape of a cylinder, for example. The protrusions 25, 26, 27 in terms of a central axis of the support element 20 can be disposed on the same diameter or on different diameters.

[0057] It is preferable for the central axis of the support element 20, when viewed in a cross section, to be provided between the protrusion 25, on the one hand, and the protrusions 26, 27, on the other hand. For example, the protrusions 25, 26, 27 can be provided so as to be asymmetrical in terms of the central axis of the support element 20. It is preferable for the central axis of the support element 20 to be parallel to the rotation axis 6 of the sample container receptacle 2 (and preferably to be congruent with the rotation axis 6) when the sample container receptacle 2 is received by the support element 20.

[0058] Illustrated in FIG. 1 is a state of the sample container handling system 1 in which the sample container receptacle 21 has not yet been received by the support element 20. The base 7 of the sample container receptacle 2 is spaced apart from the base 21, or from the side 23 of the latter, respectively, specifically in such a manner that none of the sample containers 3 is lifted by the protrusions 25, 26, 27. In particular, the protrusions 25, 26, 27 are not introduced into the through openings 11. Each of the sample containers 3 by way of the respective lower end thereof thus is supported on the support region 8. As a result, the openings or upper ends of the sample containers 3 are disposed so as to be substantially in a common plane. In this state it is difficult to retrieve one or more of the sample containers 3 from the sample container receptacle 2. This in particular because no adequate void, by way of which at least one of the sample containers 3 can be gripped and thereafter retrieved from the respective holding structure 4, 5, exists as a result of the sample containers 3 being disposed close together in the sample container receptacle 2.

[0059] In order for one or more of the sample containers 3 to be easily retrieved from the sample container receptacle 2, the sample container handling system 1 is therefore transferred to the state illustrated in FIG. 2. The sample container receptacle 2 in the process is moved toward the support element 20 so as to be received by the latter. In the process, each of the protrusions 25, 26, 27 passes through a respective through opening 11, as a result of which at least one sample container 3 on each of the imaginary rings A, B, C is lifted. In the state shown according to FIG. 2, in which the support element 20 receives the sample container receptacle 2, each of the protrusions 25, 26, 27 thus extends through the respective through opening 11 and, as a result, projects from the support region 8. As a result of this projecting action (i.e. protruding action), the respective sample container 3 can no longer be supported on the support region 8. Rather, it is implemented by the projecting action that the respective sample container 3 is moved relative to the support region 8 and thus moved away from the latter. The respective sample container 3 in the process moves through the respective through opening 4 and parallel to the rotation axis 6. In this way, the sample container 3 thus lifted projects from the plane in which the openings or upper ends of the sample containers 3 were previously provided. In other words, a void into which no adjacent sample container 3 extends is achieved beside the upper end of the respective lifted sample container 3, said upper end comprising the opening and/or facing away from the base 8. The respective lifted sample container 3 can be easily gripped and retrieved from the sample container receptacle 2 by way of this void. And this in particular without an only small gap between adjacent sample containers 3 having to be utilized, as illustrated in FIG. 1.

[0060] For example, it can be provided that only one sample container 3 for each imaginary ring A, B, C is lifted in relation to adjacent sample containers 3. This is already adequate for easy handling of the sample containers 3. This is because as soon as the respective lifted sample container 3 has been retrieved from the sample container receptacle 2, a further void, by way of which the sample containers 3 that are adjacent to the lifted (and already retrieved) sample container 3 can be successively retrieved from the sample container receptacle 2, is provided by the space that has been achieved by the retrieval of the lifted sample container 3.

[0061] As illustrated in FIG. 2, in the state in which the support element 20 receives the sample container receptacle 2, it is preferable for the latter by way of the side 10 thereof to be supported on the base 21 of the support element 20. The at least one lateral wall 22 in this instance here is provided such that said at least one lateral wall 22 at least partially surrounds the base 7. The lateral wall 22 here can in particular be provided in such a manner that the sample container receptacle 2, in particular the through openings 11 thereof, is aligned in a defined manner relative to the protrusions 25, 26, 27. This above all helps an operator of the sample container handling system 1 in introducing the protrusions 25, 26, 27 into the corresponding through openings 11. The lateral wall 22 can also have the effect that the sample container receptacle 2 is centered relative to the support element 20. In order for the sample container receptacle 2 to be aligned relative to the support element 20 in a particularly advantageous, thus particularly simple, manner, the base 7 of the sample container receptacle 2 can have a ramp 14. The ramp 14 here is provided such that the ramp 14, when connecting the sample container receptacle 2 to the support element 20, can impact the base 20 such as, for example, the lateral wall 22 thereof and the sample container receptacle 2 as a result is driven in the direction of the central axis of the support element 20. In such a (centered) position, it can suffice to rotate the sample container receptacle 2 about the rotation axis 6 thereof and/or to move said sample container receptacle 2 along the rotation axis 6 (for example by gravity), in order for the protrusions 25, 26, 27 to be introduced into the corresponding through openings 11. This consequently results in particularly easy handling. Alternatively or additionally, the support element 20, for example the lateral wall 22 thereof, can have a ramp 28. The ramp 28 in this instance is provided such that the latter, when connecting the sample container receptacle 2 to the support element 20, can impact the sample container receptacle 2, for example the base 7 or ramp 14 thereof, as a result of which the sample container receptacle 2 is driven in the direction of the central axis of the support element 20.

[0062] It is preferable for the sample container receptacle 2, by way of the protrusions 25, 26, 27 and the through openings 11, to be able to be transferred relative to the support element 20 and about the rotation axis 6 to a defined orientation. As can be seen in FIGS. 1 and 2, this can take place, for example, in that the protrusion 25 is correspondingly disposed and/or configured in terms of the through openings 11. This preferably takes place in such a manner that the protrusion 25 is singularly introducible into a specific through opening 11, for example singularly into one of the through openings 11 provided according to the first imaginary ring A. Accordingly, the protrusion 25 is not introducible into other through openings 11, for example into the remaining through openings 11 provided according to the first imaginary ring A and/or those through openings 11 provided according to the imaginary rings B, C, for example owing to a larger and/or other shape. It is preferable for the specific through opening 11 to have a size or width of such type that the protrusion 25 is introducible only into this through opening 11. The state in which the protrusions 25, 26,27 are each provided in a matching through opening n is provided as soon as one or more of the sample containers 3 has/have been lifted, as illustrated in FIG. 2 for example. In this way, the state in which the defined orientation is provided can be easily identified. In this state specifically, at least one sample container 3 is lifted.

[0063] It is preferable for the support element 20 to have an identification element 29 such as, for example, a numbering and/or a barcode. The identification element 29 can be provided on the lateral wall 22. In other embodiments, the identification element 29 can also be provided on the base 21, for example on a peripheral region of the base 21. The identification element 29 is able to be assigned to one or more holding structures 4, 5 and/or to one or more sample containers 3, which are provided on the same radius in terms of the rotation axis 6. The identification element 29 here is provided on the support element 20 such that the identification element 29, when the sample container receptacle 2 by means of the through openings 11 and the protrusions 25, 26, 27 has been transferred to the defined orientation as described above, (in plan view, thus when viewed in the direction of the rotation axis 6) is provided on the same radius as the holding structure(s) or sample container(s), respectively, assigned to the identification element 29. In this way, an operator of the sample container handling system can easily identify that the identification element 29 is assigned to exactly this/these holding structure(s) and/or sample container(s). For example, the identification element 29 contains items of information pertaining to the corresponding sample container 3 and/or to the content of this sample container 3. The identification element 29 can be configured so as to be integral to part of the support element 20 (for example the base 21 and/or the lateral wall 22), for example. Such an integral configuration can be implemented by an engraving, for example. In other embodiments, the identification element 29 can be provided on the support element 20 by way of a fastening means (for example a materially integral connection, preferably in the form of an adhesive tape).

[0064] Illustrated in an exemplary manner in FIG. 3 is a sample container handling system 1 according to a second preferred embodiment. It can be seen that the sample container handling system 1 according to the second preferred embodiment differs from the first preferred embodiment only in that the third handling structures 4, 5, which are disposed so as to correspond to the third imaginary ring C, are absent. Accordingly, the sample container receptacle 2 does not have the at least one third through opening u which is provided for the sample containers 3 disposed according to the third imaginary ring C. Consequently, the at least one third protrusion 27 of the support element 20 is also not required and thus not provided in this embodiment. Otherwise, the second preferred embodiment corresponds substantially to the first preferred embodiment such that the description pertaining to the first preferred embodiment applies correspondingly to the second preferred embodiment.

[0065] The invention here is not limited to the features described above. In particular, all features described above can be combined with one another in an arbitrary manner.
