Holder for reagent tray elements

1. An arrangement comprising: a plurality of carrier elements for a reagent to be introduced via the carrier elements into a microfluidic installation; a mounting that receives the plurality of carrier elements, wherein each of the carrier elements by way of the mounting is secured in all spatial directions by way of a form-fit, while keeping clear at least one receptacle region of the carrier element that receives the reagent, wherein each of the carrier elements is configured as a plug having the receptacle region at a first end side and a widening that forms a handling region at a second end side, wherein the mounting comprises a carrier plate having passage openings formed in a modular grid and in which the carrier elements are insertable leading with the receptacle region, wherein the widening of the carrier elements is formed by a flange, the carrier elements having a conical portion whereby the carrier elements are introducible into the passage openings to a stop position where the flange stops on the carrier plate so that the carrier elements have play parallel to a plane of the carrier plate, wherein in the stop position the receptacle region of the carrier elements projects from the carrier plate; and a holding plate common to all of the carrier elements and connected to the carrier plate, or a dedicated locking mechanism assigned to each of the passage openings of the carrier plate and configured to engage the flange on a side of the flange that faces away from the carrier plate.

2. The arrangement according to claim 1 , wherein the carrier element is established by way of the mounting while keeping clear a further region.

3. The arrangement according to claim 2 , wherein the further region is offset from the receptacle region and serves for handling the carrier element.

4. The arrangement according to claim 1 , wherein the mounting is configured to receive the carrier elements and dispose the carrier elements in a plane.

5. The arrangement according to claim 4 , wherein the carrier elements are arranged in a grid.

6. The arrangement according to claim 1 , wherein the carrier element is mounted with play.

7. The arrangement according to claim 1 , wherein the holding plate has passage openings aligned with the carrier elements that are inserted in the passage openings of the carrier plate.

8. The arrangement according to claim 1 , further comprising a frame, wherein the carrier plate is connected to the frame.

9. The arrangement according to claim 8 , wherein the carrier plate is sunk into the frame.

10. The arrangement according to claim 8 , wherein the holding plate is configured to be sunk into the frame.

11. The arrangement according to claim 10 , wherein the holding plate is connected to the frame in a latching manner.

12. The arrangement according to claim 8 , wherein the reagent receptacle regions of the carrier elements are disposed so as to be sunk into the frame.

13. The arrangement according to claim 1 , wherein the locking mechanism has elastic latching levers in a diametrical arrangement in pairs, said latching levers latching behind the widening and having a sliding ramp for unlatching.

14. The arrangement according to claim 1 , wherein the carrier plate is configured in multiple parts from carrier plate parts.

15. The arrangement according to claim 1 , wherein the arrangement is stackable.

16. The arrangement according to claim 8 , wherein the carrier plate and the frame are formed integrally from a vacuum-formed sheet.

17. The arrangement according to claim 16 , wherein holding regions composed of the frame and the carrier plates from a vacuum-formed sheet are connected to one another so as to form a strip, and a holding plate configured as a continuous sheet strip holds the carrier elements in the carrier plates, and/or a plurality of holding regions are capable of being rolled up.
