Abstract

The system has several test elements, each of which is individually sealed to be impermeable to water vapor. The system storing test elements facilitates removal of test elements and protects the test elements contained in it against effects from the outside.

Claims

1. A storage system for test elements for analyzing sample liquids, comprising:

a rigid storage container including a plurality of tubes having two ends, the tubes having longitudinal axis which are parallel to one another, and the tubes having openings at the two ends thereof;

foils sealing said openings of said tubes, said foils sealing interiors of said tubes from water vapor from the surroundings wherein said tubes and foils form water vapor-impermeable chambers; and

a plurality of test elements individually located in a respective water vapor-impermeable chamber, wherein an angle of 1°

to 45°

is formed between an end of each test element and the opening opposite the end of the test element.

2. A storage system of claim 1, wherein the chamber openings are rendered impermeable to water vapor by being sealed by a foil of aluminum or laminate thereof which is applied to the rigid storage container by gluing, pressing or welding.

3. The storage system of claim 1, wherein the rigid storage container is cylindrical, and cross sections of the chambers are in the form of circular segments.

4. The storage system of claim 1, further including a piercing device for piercing the sealing foil of the sealed chambers.

5. The storage system of claim 4, wherein the piercing device comprises a ram, guiding pins for guiding said ram and a cover, wherein pressure can be applied to the cover which transmits a force to the ram to cause the ram to pierce the sealing foil.

6. The storage system of claim 1, wherein a drying agent is contained in each chamber.

7. The storage system of claim 1, wherein the angle between the end of the test strip and the opening opposite the end of the test strip is 5°

to 45°

.

8. The storage system of claim 1, wherein a data carrier is fixed to the rigid storage container.

9. A storage system according to claim 1, wherein each said chamber covers test element inside along the longitudinal axis, but does not directly contact said test element at all sides.

10. A storage system according to claim 1, wherein said test strip is removable from the tube through either of said two openings.

11. A process for providing a test element which has not been exposed to deleterious amounts of water vapor, said method comprising

providing a plurality of test elements in sealed chambers of the system of claim 1,

pealing a sealing foil off of at least part of an opening of a first chamber to expose a test element contained in the first chamber;

and

removing the test element from the first chamber.

12. A process for providing a test element which has not been exposed to deleterious amounts of water vapor, said method comprising

providing a plurality of test elements in sealed chambers of the system of claim 1,

piercing a foil sealing an opening of a first chamber of said system;

and

exerting mechanical pressure on the test element in the first chamber to, cause the test element to pierce a second foil of a second opening of the first chamber to push the test element out of the first chamber.

13. Process of claim 12, wherein the test element is pushed from the first chamber directly into an instrument for analyzing the sample liquids.

14. A storage system for test elements for analyzing sample liquids, comprising;

a rigid storage container including a plurality of tubes having two ends, the tubes having longitudinal axis which am parallel to one another, and the tubes having openings at the two ends thereof;

foils sealing said openings of said tubes, said foils sealing interiors of said tubes from water vapor from the surroundings wherein said tubes and foils form water vapor-impermeable chambers;

a plurality of test elements individually located in a respective water vapor-impermeable chamber; and

pushing means for pushing a first end of one of the test elements such that a second end of the test element pierces a foil sealing the opening of the tube which is opposite the second end of the test element.

15. The storage system according to claim 14, wherein an angle is formed between an end of each test element and the opening opposite the end of the test element.

16. The storage system according to claim 15, wherein the angle is between 1°

to 45°

.

17. A storage system according to claim 14, wherein said pushing means pierces a foil sealing the opening of the tube which is opposite the first end of the test element.

18. A storage system according to claim 14, wherein said storage container is cylindrical.

19. A storage system according to claim 14, wherein said piercing means comprises a ram, guiding pins for guiding said ram and a cover, wherein pressure can be applied to the cover which transmits a force to the ram to cause the ram to pierce a foil.
