Process for the production of analytical devices
First Claim
1. A process for the production of a analytical device with a capillary-active zone in which(a) a carrier layer is provided;
- (b) a spacer layer is laminated onto the carrier layer;
(c) a contour which determines the shape of the capillary-active zone is cut through the spacer layer;
(d) those parts of the spacer layer which are not required for shaping the capillary-active zone are removed from the carrier layer; and
(e) a cover layer is mounted on the spacer layer so that the capillary-active zone and the devices are formed.

Abstract
A process for the production of analytical devices is provided in accordance with the present invention. Analytical devices include analytical test elements with a capillary-active zone for examining liquid samples. In the process a carrier layer is prepared, a spacer layer is laminated onto the carrier layer, a contour is punched, cut or stamped through the spacer layer laminated onto the carrier layer which determines the shape of the capillary-active zone, those parts of the spacer layer which are not required to form the capillary-active zone are removed from the carrier layer and a cover layer is applied to the spacer layer to result in a capillary-active zone. The process according to the invention is preferably suitable for manufacturing analytical devices from tape material.
