5mm外徑經(jīng)濟(jì)型NMR核磁管
經(jīng)濟(jì)型NMR樣品管由符合美國(guó)標(biāo)準(zhǔn)和材料協(xié)會(huì)(American Society for Testing and Materials)E438標(biāo)準(zhǔn)中規(guī)定的一型B類硼硅玻璃制成。此類玻璃在工業(yè)上通常稱為N51A玻璃。基于此類玻璃的物理性質(zhì)，N51A玻璃的抗熱膨脹能力要遠(yuǎn)低于通常稱為Pyrex玻璃的ASTM
一型A類玻璃 (ASTM一型A類玻璃是精密型產(chǎn)品的材料)。同時(shí)由于N51A玻璃含有微量的順磁物質(zhì)Fe2O3，其MHz級(jí)別要低于同等精度的精密型玻璃。
5mm外徑經(jīng)濟(jì)型NMR核磁管推薦使用在室溫下測(cè)量小分子(分子量小于1500）的1維NMR實(shí)驗(yàn)中。加熱或者冷卻經(jīng)濟(jì)型管都可能導(dǎo)致管壁由于熱漲冷縮造成的破裂1。除了WG-1000系列，其余經(jīng)濟(jì)型產(chǎn)品均提供可拋棄型管帽。
