摘要: The method for manufacturing a sample tube the use in nuclear magnetic resonance apparatus comprising steps of: inserting core bar into tubular body made of glass or quartz, having stepped portion and remaining portion, with corresponding to receiving chamber being larger diameter than portion; gradually an electric furnace heating while allowing suction from vacuum pump act on interior body, thereby whole intimately attached shaping along outer peripheral surface bar; withdrawing outside lower end opening body; sealing by form bottom tube; grinding so that will be equal diameter.
