液氮儲存容器有危險性嗎

時間:2023-08-03 14:15來源:班德公司 作者:小編 點擊:

  低溫容器中的液氮儲存容器因冷凍生物樣本方便、型號替代性強而深受科研實驗室和畜牧業冷凍精華客戶的喜愛。由于儲存的樣本很有價值,客戶更擔心它的安全性和可靠性。

  使用液氮儲存容器有危險嗎?這個問題還是要相對來說的!無危險的前提是操作得當,按產品說明書進行。

  大多數危險是由于操作錯誤,如為了避免液氮揮發,密封液氮罐,導致自然揮發N2無法排出,導致罐爆炸;或徒手取樣液氮,傷害自己凍結等。

  液氮儲存容器為敞口常溫罐,無壓力,也不會產生壓力,

  安裝液氮后,由于液氮自然揮發,氣體有壓力,不能一起排出,到臨界點爆炸。為了避免這種危險,液氮儲存容器的頸塞設計相對松動,以便N2排出。

  然而,一些客戶會試圖密封容器,因為他們希望液氮一直儲存下來,結果往往是爆炸和罐子損壞;幸運的是,它不會傷害人,只會破壞樣品;不幸的是,樣品被破壞了。自增壓液氮罐

  因此,如果液氮儲存容器不危險,就要嚴格按照使用說明書,不要密封罐子,隨意更換頸塞,使用時注意安全防護。
