Sampling device for liquid samples

A device for sampling liquid samples comprising:

• a carrier;
• an intermediate layer mounted to the carrier;
• a secondary intermediate layer mounted to the carrier a distance from the intermediate layer, said distance between the immediate layers defining a sampling site;
• a cover mounted to the intermediate layer and providing a vent hole, said cover protruding beyond the entire intermediate layer in the sampling site;
• and
• a secondary cover mounted to the secondary intermediate layer, said secondary cover protruding beyond the entire secondary intermediate layer in the sampling site, wherein
• the carrier, the intermediate layer, and cover define a capillary-active channel extending from the vent hole to the sampling site, said capillary-active channel widens towards the sampling site, and
• the carrier, the secondary intermediate layer, and secondary cover define a secondary capillary-active channel extending from and returning to the sampling site.
