Choosing the right neck size for a liquid nitrogen tank can save half of the liquid nitrogen!

The size of the neck (opening) of the liquid nitrogen tank directly determines two key issues:
 
Liquid nitrogen consumption rate (smaller neck opening saves more)
 
Convenience of retrieval and placement (larger neck opening is more convenient)
 
How to choose? Remember three sentences
Long term storage with small openings (50-60mm)
 
Suitable for sample libraries and research institutions
 
Save liquid nitrogen! Less evaporation by 30% compared to larger diameters
 
Frequently access the selection port (80-100mm)
 
Suitable for hospitals and breeding centers
 
Take samples without getting stuck
 
Large sample selection mouth (120mm+)
 
Specialized for organ packaging and large bags
 
But liquid nitrogen consumes quickly, it's best to have automatic replenishment
 
Guide to Avoiding Pits
Don't just look at the price! Small necked cans are cheap, but taking samples every day can be frustrating
✔  Choose a neck with anti frost design (to reduce freezing and getting stuck)
 
Summary in one sentence:
 
The sample has not moved for several years → small neck opening
 
Take it every day → Big Neck Mouth
