Selecting the right liquid nitrogen (LN₂) tank isn’t as complicated as it sounds—if you know what to look for. In just half a minute, here’s your quick guide:
Determine Your Purpose
Storage: For long-term preservation, choose a storage Dewar tank with excellent insulation.
Transport: For moving samples, pick a transport tank with added protective structure.
Frequent Dispensing: For regular nitrogen supply, a self-pressurizing tank is ideal.
Check the Capacity
Common sizes range from 2L to 50L. Smaller tanks are portable; larger ones store more nitrogen and maintain temperature longer.
Consider the Neck Diameter
The opening affects what can be stored and how easily samples can be retrieved. A wider neck allows quicker access but increases evaporation rates.
Look at Hold Time
This is how long the tank can keep nitrogen without refilling. If you need stability over weeks, go for longer static evaporation times.
Match Accessories
Ensure compatibility with canisters, locking lids, or level gauges for your application.
By matching purpose, size, neck diameter, and hold time, you’ll quickly find a tank model that meets your exact needs—saving time, money, and hassle.
