Disposable sampling apparatus for drawing samples from melts by lowering thereof into the melt and comprising a mold embedded in a sand body, a tube constituting an inlet for the molten material into the mold and projecting out of the sand body, and a tubular sleeve surrounding a portion of the sand body and at least a portion of the inlet tube to the mold. The novelty features of the invention reside in the fact that the sleeve is arranged on a portion of the sand body adjacent the inlet tube and extends therefrom outwards around the inlet tube, and that there is a gas flow path through said sand portion from the recess formed between the inlet tube and the sleeve to an open portion of the sand body.
