Abstract

A process for the production of at least one analytical device is disclosed. The analytical device comprises at least one capillary element. The process comprises providing at least one carrier layer; providing at least one spacer layer; applying the spacer layer on top of the carrier layer; providing at least one cover layer; and applying the cover layer on top of the spacer layer. The process further comprises at least one cutting step. At least one capillary channel of the capillary element is cut out from the spacer layer. The cutting step is performed by using at least two cutting tools. The cutting tools complement one another to form a contour of the capillary channel.
