worthington LABS20K气相液氮罐
美国Worthington沃辛顿液氮罐LABS系列中的当样品存储在液氮平面之上，依旧保持一个低温状态，气相是一个非常安静的液氮冷缺工艺，随着离开液氮平面越远，气相液氮罐内温度随之增加，在许多生物的应用程序存储中这是一个显著的温度差，但是LABS根据控温系统,可以严格保温温度波动情况，在温度低于限定值时，自动开启液氮补充模式。

使用注意事项：
液氮供应压力入口应控制在10 psig（0.7兆帕/ 69 kPa）到22 psig（1.5兆帕/ 152 kPa）的范围，为*性能，较高的工作压力会增加传输损耗，造成液氮罐内液体流速过快，从而产生虚假信号，发生对液位控制器箱欠满的虚假报警。
