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.
Claims13
A process for the production of at least one analytical device, the analytical device having at least one capillary element, the process comprising:
- 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;
- applying the cover layer on top of the spacer layer;
- and cutting out at least one capillary channel of the capillary element from the spacer layer, wherein the cutting out is performed by using at least two cutting tools, wherein each cutting tool generates a cutting line that overlap and complementing one another to form a contour of the capillary channel and an overlapping region, wherein the overlapping region compensates for varying distances between the cutting lines, wherein the cutting tools are individually controlled with regard to at least one cutting parameter.
