2.5L Aluminum Liquid Nitrogen Container

2.5L Aluminum Liquid Nitrogen Container

A 2.5 L aluminum liquid nitrogen container is a cryogenic dewar built specifically to store and transport a few litres of liquid nitrogen (LN₂) at extremely low temperatures (~−196 °C). These small-capacity dewars are ideal when you need compact, portable cryogenic storage for lab vials, veterinary semen, small biological samples, or field applications. The aluminum construction balances lightweight handling with strong structural performance.

❄️ Key Features

High-Strength Aluminum Alloy Body:
Provides good cryogenic durability while keeping the container relatively lightweight for easier handling and transport.

Vacuum-Insulated Design:
Double walls with vacuum insulation minimize heat transfer, reducing evaporation loss and maintaining LN₂ temperature for longer static hold times.

Compact Capacity (~2.5 L):
Ideal for storing a small number of samples or for transferring LN₂ from a large tank to your point of use without needing large infrastructure.

Portable & Easy to Use:
Many models have a wide neck opening and carry handle to make filling and sample retrieval quick and safe.

Low Evaporation:
Typical static evaporation losses for similar small dewars are in the range of ~0.1–0.12 L/day, with static holding times around 20+ days under standard conditions.

🧪 Typical Uses

Cryopreservation of Biological Samples:
Storing vials of semen, embryos, cells, or tissue sections at ultra-low temperatures for lab or veterinary use.

Veterinary & Agriculture:
Short-term and transport storage for semen or embryo samples in breeding programs.

Laboratory & Research Applications:
Holding LN₂ for bench use, rapid freezing, or periodic sample retrieval.

Portable Field Work:
Small dewars can be used outside fixed facilities for field sample collection and handling.
