Why Choose a 4 Liter Liquid Nitrogen Dewar?
A 4 liter liquid nitrogen dewar is one of the most popular sizes for everyday laboratory and clinical use. Its compact footprint makes it easy to store on a bench or carry to the field, while its 4L capacity is sufficient for most short-term cryogenic tasks – from dispensing LN2 into smaller containers to temporarily holding biological samples during transfer.
Compared to larger dewars, the 4L model is ideal when you need:
Portability without sacrificing adequate liquid nitrogen volume
A low evaporation rate to reduce LN2 consumption and costs
Quick access to cryogenic storage in a small lab or clinic space
A dedicated vessel for field sampling or mobile cryogenic workflows
How Our 4L Dewar Compares to Other Sizes
Choosing the right liquid nitrogen dewar size depends on your storage duration and volume needs. Here is a quick comparison to help you decide:
| Capacity | Best For | Hold Time (approx.) |
|---|---|---|
| 2 Liter | Minimal lab tasks, bench-top use | ~7 days |
| 4 Liter | Routine research labs, IVF clinics, sample transfer | ~10–14 days |
| 10 Liter | Core labs, frequent LN2 dispensing, biobanking | ~30 days |
| 20 Liter | Hospital labs, industrial applications | ~60+ days |
The 4 liter model strikes an optimal balance between portability and practical hold time, making it the top choice for researchers and clinicians worldwide.

Frequently Asked Questions – 4 Liter Liquid Nitrogen Dewar
Q: How long does a 4 liter liquid nitrogen dewar hold LN2?
With an evaporation rate of approximately 0.19 liters per day, a fully filled 4 liter dewar can hold liquid nitrogen for roughly 10 to 14 days under normal static conditions. Frequent opening or transport may slightly reduce hold time.
Q: Can a 4L dewar be used to store biological samples?
Yes. Our 4 liter dewar is suitable for short-term cryogenic storage of cryo vials, sperm samples, embryos, and other biological specimens. For long-term sample storage, we recommend pairing it with a dedicated cryogenic storage dewar with canister inserts.
Q: Is the 4 liter liquid nitrogen dewar suitable for transport?
It is designed primarily as a lab or bench-top vessel. For transport applications, we recommend using our certified LN2 dry shipper series, which are engineered to carry samples safely in the vapor phase during transit.
Q: What accessories are compatible with this dewar?
Replacement caps, carry bags, roller bases, liquid withdrawal devices, and protective gloves are all available as optional accessories. Contact our team for a complete accessory list.
Q: What certifications does Banagee's dewar carry?
Our dewars are CE and ISO certified and manufactured under strict quality control standards in our ISO-compliant facility in China, ensuring they meet global export requirements.
