How to Choose the Right Scientific Dewar Containers

The ideal liquid nitrogen (LN2) storage dewar for your facility or project will depend on how you plan to use it.

Consider your needs regarding:

• Footprint and capacity: If you have limited space or require portability, opt for a smaller model. Larger models will increase your LN2 capacity and reduce refill frequency
• Static hold and evaporation rate: The less evaporation that occurs, the longer you can go without refilling LN2. However, especially sensitive materials may require a model that prioritizes hold time over evaporation rate
• Access: Smaller device necks can conserve more LN2 when dispensing, but may be more challenging to use and slow down operations that require frequent dispensing
• Portability: The more compact your laboratory dewar flask is, the easier it will be to transport and use in field research. If portability is not a concern, a larger model may offer more benefits
• Accessory compatibility: While IC Biomedical’s catalog usually aligns with standard accessories (e.g., canisters, racks, transfer lines), check the specifications of the models you are reviewing to make sure they will integrate with your existing workflow
