What we should know about Liquid nitrogen tank

----What is Liquid nitrogen tank ?

Liquid nitrogen tank is a container which used to statis storage or transport liquid nitrogen.Liquid nitrogen 

is -197℃，it has wide usage for samples cryogenic storage in laboratory and life. 

----What are liquid nitrogen tank used for ?

Liquid nitrogen tanks are units used for the conservation of laboratory samples at very low temperatures. 

Due to fast freezing, it prevents damage to structures and protects processes from moisture, oxidation and 

contamination.

----How long time the liquid nitrogen can store in a tank ?

It depends. Liquid nitrogen tank has normal neckdiameter 50mm,also have wide neck with diameter 80mm,

125mm,210mm.  The neck diameter affect the liquid nitrogen evaporation ratio directly. So,the storage time 

of small neck is longer than wide neck. 

----How to choose small neck or wide neck liquid nitrogen tank ?

It depends on your sample. If it is big,surely choose wide neck. Otherwise,50mm is enough.

----How can I know the liquid nitrogen residue after times of using ?

We have a smart cap,it designed to help user to real-time monitor the temperature and liquid nitrogen level

inside of tank without open the lid. Also fully monitor the storage environment of samples in the tank safety.

When it collects liquid level and temperature data, it transmits the collected data to the data relay for storage

at a fixed frequency (10 minutes per time) by 2.4 G wireless mode.
