A sampling device for molten metals with a sample chamber arranged in a paperboard tube has an inflow canal leading through the paperboard tube, the canal being formed essentially of a heat-resistant inflow tube, such that the outer end of the inflow tube ends below (inside) the outer circumference of the sampling device and is closed off by a delayed-action device. In order to create a sampling device in which the intrusion of contaminants into the sample chamber is prevented, especially slag particles, gas occlusion particles and particles of the paperboard tubes, the delayedaction device is constructed as a multi-layered cap, whereby between cap and paperboard tube an intermediate space is formed, which is filled with cement.
