1915漢普儀 純氧分析器 實驗室玻璃儀器，固體吸收器概述及用途：

漢(han)普儀(yi)，1915漢(han)普儀(yi)（純氧分析器），也叫漢(han)氏(shi)氣體分析器：漢(han)普儀(yi)是用硼硅玻(bo)璃經(jing)爐工和燈(deng)工精心焊接而成(cheng)。做工考究，制(zhi)作精良，經(jing)濟實用。

使(shi)用時需要裝置在特制(zhi)木(mu)架(jia)上。漢氏氣(qi)(qi)體分(fen)析器適應氣(qi)(qi)體分(fen)析的(de)固體吸收，廣泛應用于制(zhi)氧(yang)設備對氧(yang)氣(qi)(qi)和氮氣(qi)(qi)的(de)純度試(shi)驗。

1915純氧分析器造型及(ji)原(yuan)理：

漢普儀造型及原理:漢普儀是用硼硅玻璃經爐工和燈工精心焊接而成。漢普儀的結構是由一個圓形吸收球與一個圓形球焊接而成，在吸收球的下端有一個開口，便于放入固體吸收器或填料，然后用膠塞塞住，其上端接一只毛細管，是接氣體量管用。
