Thermo Model 819 Arctic Express 4.3L Cryogenic Dewar for Liquid Nitrogen Sample Transport

The Thermo Model 819 Arctic Express Cryogenic Dewar is engineered for secure and reliable transportation of infectious or biological samples at cryogenic temperatures, essential in molecular diagnostics and bioprocessing workflows. Constructed from lightweight aluminum, this LN2 storage tank features a 4.3-liter capacity with a static evaporation rate of 0.2 L/day, enabling a 21-day liquid nitrogen holding time critical for long-distance cold-chain shipping in biotechnology and biomedical research.

Key design elements include an innovative absorbent material to prevent LN2 spillage, a lockable lid with an internal security compartment for enhanced sample protection, and a canister capable of holding up to 48 vials of 1.2 mL or 2 mL size. These features make it widely adopted in synthetic biology research and clinical diagnostics for safe cryogenic storage and transport.

The unit’s compact dimensions and low weight (~1.09 kg) optimize portability for cryogenic sample handling in cell imaging labs, biomanufacturing facilities, and molecular cloning workflows where temperature stability and contamination prevention are paramount.
