Abstract

A storage container for holding analytical devices, the storage container being made of a rigid material and containing separate chambers in each of which at most one analytical device can be accommodated, wherein the chambers are in a regular geometric arrangement in relation to one another and each of the chambers has at least two opposite openings each sealed by a foil, wherein at least one of the chambers comprises a means for fixing the position of an analytical device in the chamber. In addition the invention concerns a system for storing analytical devices containing a storage container according to the invention and two or more analytical devices.

Claims

1. A system for holding analytical devices, the system comprising

a storage container comprising a rigid material containing separate chambers in each of which at least one analytical device can be accommodated, wherein each of the chambers has at least two opposite openings each opening being sealed by a foil, wherein at least one of the chambers comprises a means for fixing the position of the analytical device in the chamber,

the at least one analytical device formed to perforate the foil,

a compact measuring instrument including functional components and formed to hold the storage container therein, and

means for holding the storage container in the measuring instrument and for the removal of individual analytical devices from the storage container wherein the storage container is positioned relative to the functional components of the measuring instrument in order to remove the individual analytical device from the storage container.

2. The system of claim 1 wherein the means for fixing the position of the analytical device comprises a partial constriction of the chamber.

3. The system of claim 2 wherein the partial constriction comprises at least one elevation in the wall of the chamber which protrudes into the interior of the chamber.

4. The system of claim 1 wherein the at least two openings in each chamber are sized such that the analytical device can pass through only one of the openings.

5. The system of claim 4 wherein the opening of each chamber through which the analytical device cannot pass is sized to allow passage of a plunger which can be used to push the analytical device out of the chamber.

6. The system of claim 1 wherein each of the chambers contains a guide groove.

7. The system of claim 1 wherein the storage container further comprises at least one outer surface that is sealed by foil, the outer surface having an elevation present thereon that prevents direct contact between the foil sealing the outer surface and a flat support surface when the storage container is placed on such a flat support surface.

8. The system of claim 7 wherein the storage container further comprises a second outer surface that is sealed by foil, the second outer surface having an elevation present thereon which prevents direct contact between the foil sealing the second outer surface and a flat support surface when the storage container is placed on such a flat support surface.

9. A system for storing analytical devices comprising

at least one storage container comprising a rigid material containing separate chambers in each of which at most one analytical device can be accommodated, wherein each of the chambers has at least two opposite openings each opening being sealed by a foil,

the plurality of analytical devices formed to perforate the foil,

a compact measuring instrument including functional components and which is suitable for holding at least one of the storage containers, and

means for holding the storage container in the measuring instrument and for the removal of individual analytical devices from the storage container wherein the storage container is positioned relative to the functional components of the measuring instrument in order to remove the individual analytical device from the storage container and

wherein at least one of the chambers comprises a partial constriction that is sized to bend the analytical device to create a bending strain of the analytical device against the rigid material.

10. The system of claim 9 wherein the analytical devices are test elements for analyzing liquids.

11. The system of claim 9 wherein a plurality of the analytical devices are provided per storage container.

12. The system of claim 9 further comprising a system container and the at least one storage container is contained in the system container.

13. The system of claim 12 further comprising a desiccant positioned in the system container.

14. The system of claim 12 wherein a plurality of the storage containers is contained in the system container.

15. The system of claim 14 further comprising a desiccant positioned in the system container.

16. A system for holding analytical devices, the system comprising:

a body having an upper side and an under side, the body being formed to include at least one chamber extending between the upper side and the under side, the chamber being defined by a chamber wall extending between a first opening at the upper side and a second opening at the under side, the chamber wall having a means for fixing the position of one analytical device in the chamber by bending the analytical device to create a bending strain of the analytical device against the chamber wall,

a first foil extending across the upper side, the first foil being formed to seal the first opening, a second foil extending across the under side, the second foil being formed to seal the second opening,

the analytical devices formed to perforate the first foil,

a compact measuring instrument including functional components and formed to hold the body therein, and

means for holding the storage container in the measuring instrument and for the removal of individual analytical devices from the storage container wherein the storage container is positioned relative to the functional components of the measuring instrument in order to remove the individual analytical device from the storage container.

17. The system of claim 16 wherein the body includes an elevation that extends from the upper side.

18. The system of claim 17 wherein the body is further formed to include at least one desiccant chamber spaced-apart from the at least one chamber.

19. The system of claim 16 wherein each of the chambers contains a guide groove extending from the opening at the underside.
