The device for pouring specimen commonly used in PGC and NGC includes a gas tube (1), a temperature controller (2), a stopper (3), a diaphram (4), a main body (5) of the specimen pouring device, and tube fittings (7). The gas tube (1) having a form of bent loops is made to get through the temperature controller. A gas inlet (10) of the gas tube is L1 away from the inner end of the tube fittings. The distance, L1, is 70-90% of the distance, L2, which is the whole length of the main body of the specimen pouring device.
