Abstract

A device for storing and/or treating chemicals is described. The device includes a glass casing provided with a receiving cavity for storing chemicals therein, and further includes a transponder having a memory, the transponder being arranged in the device such that it cannot be affected by the chemicals.

Claims

1. A device for storing and/or treating chemicals, comprising:

a casing in the form of a sampling tube having two open ends, the sampling tube defining a receiving cavity for storing chemicals therein, the receiving cavity accommodating an absorption material,

wherein the sampling tube is provided with a transponder including a memory, the transponder being arranged in the sampling tube such that it cannot be affected by the chemicals, the transponder being arranged outside the absorption material.

2. A device according to claim 1,

characterized in that the transponder is melted-in in a closed glass housing which constitutes an inseparable part of the device.

3. A device according to claim 1 characterized in that the transponder comprises an antenna.

4. A device according to claim 3,

characterized in that the antenna is provided on the glass casing by a vapor deposition technique.

5. A device according to claim 4,

characterized in that the vapor-deposited antenna is designed as a layer of metal ions vapor-deposited in a spiral path.

6. A device according to claim 3,

characterized in that the antenna is designed as a coil-shaped element accommodated in the glass housing.

7. A device according to claim 1,

characterized in that the memory of the transponder is programmable.

8. A device according to claim 7,

characterized in that the memory of the transponder contains a non-erasable identification number.

9. The device according to claim 1 wherein the sampling tube is received in a package which is made of glass and filled with inert gas, the package having closed ends.

10. The device according to claim 1 wherein the absorption material is confined between two sieves.

11. The device according to claim 10 wherein the sieves are glass wool plugs.

12. The device according to claim 10 wherein the sieves are metal sieves.

13. The device according to claim 1 wherein the transponder is fixed between two sieves.

14. The device according to claim 13 wherein the sieves are glass wool plugs.

15. The device according to claim 13 wherein the sieves are metal sieves.

16. The device according to claim 1 wherein the transponder is fixed between two confined portions of the sampling tube.
