16L Liquid Nitrogen Container

16L Liquid Nitrogen Container

A 16 L liquid nitrogen container (also called an LN₂ dewar) is a cryogenic vacuum-insulated storage vessel engineered to hold liquid nitrogen at extremely low temperatures (≈ −196 °C / −320 °F). It’s widely used in laboratories, medical facilities, fertility clinics, research institutions, and animal husbandry for cryopreservation, semen and embryo storage, biological sample preservation, and safe transport of cryogenic materials.

❄️ Key Features

Large Cryogenic Capacity:
Designed to hold ~16 litres of liquid nitrogen — ideal for medium-scale cryogenic storage needs.

Vacuum-Insulated Design:
Double-walled insulation minimizes heat transfer to reduce nitrogen boil-off and extend holding time.

Low Evaporation Loss:
Typical static evaporation rates for dewars around this size are low, ensuring efficient LN₂ use over prolonged periods.

Robust Construction:
Made from lightweight yet durable materials (often aerospace-grade aluminium) that withstand cryogenic temperatures and everyday handling.

Portable & Easy Handling:
While heavier than small dewars, many models come with handles and optional accessories (like caster bases or carts) for easier transport within labs or facilities.

🧪 Typical Applications

Cryopreservation & Biobanking: Storing semen, embryos, cells, tissues, and other biological samples in static liquid phase at ultra-low temperatures.

Medical & Research Laboratories: Long-term storage of reagents and cryogenic samples.

Veterinary & Agriculture: Animal semen and embryo storage for artificial insemination programs.

Transport: Short-distance transport of LN₂ samples (with appropriate safeguards).
