A sampling tube includes a sealed metallic tube having a fusible end cap at an extending end which, when submerged in a molten bath, admits the molten sample into the evacuated tube. The tube has a liner which is either frangible or has a nonadhering surface defining a substantially uniform, cross-sectional diameter to freely allow the molten sample to enter the tube and solidify in the liner as the sample tube is removed.
