Labeled device

A labeled device comprising a first surface and a second surface, at least one reaction zone and at least one labeling zone, wherein

• the at least one reaction zone is arranged on the first or the second surface and the at least one labeling zone is arranged on the first or the second surface,
• the at least one reaction zone allows performing a reaction, preferably a chemical, physical, biochemical or biological reaction,
• the at least one labeling zone contains a marker, wherein the marker allows the identification of the device and wherein
• the labeled device is obtained by a method for the preparation of the labeled device, wherein
• a first chemical compound is added to the at least one reaction zone using a first delivery device,
• the marker is added to the at least one labeling zone prior, during or after the adding of the first chemical compound to the at least one labeling zone using a second delivery device,
• wherein the at least one reaction zone is arranged in a plane forming a reaction plane, and the at
• least one labeling zone is arranged in a plane forming a labeling plane and wherein the reaction plane and the labeling plane are at least partially overlapping.

A method for the manufacture or making of a device, comprising:

• providing a device comprising a first surface and a second surface, at least one reaction zone and at least one labeling zone, wherein
• the at least one reaction zone is arranged on the first or the second surface and the at least one labeling zone is arranged on the first or the second surface,
• the at least one reaction zone allows performing a reaction, preferably a chemical, physical, biochemical or biological reaction, and
• the at least one labeling zone contains a marker or allows arranging a marker therein, wherein the marker allows the identification of the device;
• and
• arranging a marker to the at least one labeling zone
• wherein
• a first chemical compound is added to the at least one reaction zone using a first delivery device and
• the marker is added to the at least one labeling zone prior, during or after the adding of the first chemical compound to the at least one labeling zone using a second delivery device.
