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 which is made of glass and is provided with a receiving cavity for storing chemicals therein, the casing being designed as a tube with two open ends, the device further comprising a transponder including a memory, the transponder being arranged in the device such that it cannot be affected by the chemicals, the transponder being melted-in in a closed glass housing, the housing being covered with absorption material.

2. A device according to claim 1, the transponder comprising an antenna.

3. A device according to claim 2, the antenna being provided on the glass casing by a vapor deposition technique.

4. A device according to claim 3, the vapor-deposited antenna being designed as a layer of metal ions vapor-deposited in a spiral path.

5. A device according to claim 2, the antenna being designed as a coil-shaped element accommodated in the glass housing.

6. A device according to claim 1, the device being a sampling tube, the receiving cavity accommodating an absorption material, and the transponder housing being embedded in the absorption material.

7. A device according to claim 1, the memory of the transponder being programmable.

8. A device according to claim 7, the memory of the transponder containing a non-erasable identification number.
