ABSTRACT:
A sampler for molten metal has a flat sample chamber arranged in a carrier tube, an inlet duct with an inflow opening arranged on the side of the flat sample chamber facing away from the immersion end of the carrier tube, and a wall surface which forms a sample analysis surface running parallel to the axis of the carrier tube. In order to create a sampler with which high-quality flat samples can be obtained and which can be easily removed from the sampler, a prechamber is arranged inside the carrier tube, at the end of the inlet duct facing away from the immersion end of the carrier tube, above the flat sample chamber and between the inlet duct and the inflow opening. The prechamber has a cross-sectional area transverse to the inflow direction through the inflow opening which is greater than the cross-sectional area of the inflow opening, and a cross-sectional area transverse to the axis of the inlet duct in the vicinity of its inlet which is greater than the cross-sectional area of the inlet of the inlet duct.
