Abstract

A device for sampling liquid samples is provided comprising a capillary-active channel, a sampling site, and a determination site. The capillary-active channel is configured for transporting a sample from the sampling site to the determination site. The capillary-active channel is substantially formed by a carrier, a cover and an intermediate layer located between the carrier and cover. The carrier protrudes beyond the cover in the area of the sampling site. The intermediate layer is displaced towards the back in the direction of the determination site in the area of the sampling site so that the carrier as well as the cover protrude beyond the intermediate layer. The device allows sample to be applied from above onto the exposed area of the carrier in the area of the sampling site and also allows sample to be applied from the side.
