worthington LABS20K氣相液氮罐
美國Worthington沃辛頓液氮罐LABS系列中的當(dāng)樣品存儲在液氮平面之上，依舊保持一個低溫狀態(tài)，氣相是一個非常安靜的液氮冷缺工藝，隨著離開液氮平面越遠(yuǎn)，氣相液氮罐內(nèi)溫度隨之增加，在許多生物的應(yīng)用程序存儲中這是一個顯著的溫度差，但是LABS根據(jù)控溫系統(tǒng),可以嚴(yán)格保溫溫度波動情況，在溫度低于限定值時，自動開啟液氮補(bǔ)充模式。

使用注意事項：
液氮供應(yīng)壓力入口應(yīng)控制在10 psig（0.7兆帕/ 69 kPa）到22 psig（1.5兆帕/ 152 kPa）的范圍，為*性能，較高的工作壓力會增加傳輸損耗，造成液氮罐內(nèi)液體流速過快，從而產(chǎn)生虛假信號，發(fā)生對液位控制器箱欠滿的虛假報警。
