摘要

The present invention relates to a sample tube (10) for NMR measurement, obtainable by providing a reference material (13) for NMR measurement to a first tube (11) closed at one end, providing a second tube (12) closed at one end into the first tube, and fusing the other end of the first tube and the other end of the second tube to seal a gap between the other end of the first tube and the other end of the second tube.
