Product Name Portable Liquid Nitrogen Dewar
Product Overview The Portable Liquid Nitrogen Dewar is designed for cryogenic storage of livestock semen and other biological materials. Its lightweight aluminum construction and vacuum-insulated structure provide a practical solution for cattle breeding farms, dairy operations, veterinary facilities and artificial insemination programs.

The portable format allows convenient handling between breeding areas while the insulated vessel helps maintain stable cryogenic storage conditions.
Key Features
  • Lightweight aluminum alloy construction
  • Vacuum-insulated cryogenic storage structure
  • Low liquid nitrogen consumption
  • Portable handle for convenient movement
  • Internal canisters for organized semen storage
  • Easy access for sample retrieval
  • Suitable for farm and field AI operations
  • Customizable capacity and canister configuration
Structural Components
  • Outer vessel: Lightweight protective aluminum housing.
  • Inner vessel: Reservoir for liquid nitrogen and stored samples.
  • Vacuum space: Thermal insulation between the vessel walls.
  • Neck tube: Narrow opening designed to reduce heat transfer.
  • Insulated lid: Helps limit heat ingress during storage.
  • Canisters: Used to organize semen straws and biological samples.
  • Carry handle: Supports convenient manual handling and transportation.
Working Principle Liquid nitrogen is stored inside the inner vessel to create the cryogenic environment required for frozen semen preservation. The vacuum-insulated space between the inner and outer vessels minimizes heat transfer from the surrounding environment.

Frozen semen straws are placed inside suitable canes, goblets and canisters for organized storage. The internal arrangement supports efficient sample identification and retrieval during livestock artificial insemination.
