Thermo Scientific 819 Manual Fill 4.3L LN2 Dewar for Cryogenic Sample Storage

The Thermo Scientific 819 Manual Fill LN2 Dewar is a precision-engineered cryogenic storage container designed for reliable preservation and transport of biological samples at ultra-low temperatures. Ideal for applications in molecular diagnostics, biotechnology, and bioprocessing, this 4.3-liter dewar effectively supports workflows requiring sustained cryogenic conditions essential for biomanufacturing and synthetic biology research.

Key technical features include:

• Manual fill design compatible with standard liquid nitrogen refilling protocols
• Capacity to hold up to 8 canes or canisters, facilitating organized storage of samples
• Each cane accommodates 6 vials of 1.2 mL size, or a total of 120 cryo straws, supporting diverse vial sizes from 1.2 mL up to 5 mL for versatile sample volumes
• Static evaporation rate of 0.2 liters per day ensures minimized LN2 loss, enabling a static holding time of up to 21 days, crucial for extended sample preservation during bioprocessing and clinical diagnostics
• Supplied with one canister included for immediate integration into cryogenic storage workflows
• Compact and lightweight with a net weight of approximately 1.09 kilograms, promoting ease of handling in laboratory and clinical environments

This LN2 Dewar supports critical cold chain maintenance for sensitive biological materials, making it widely adopted in fields such as cell imaging, live-cell preservation, and neuroimaging sample storage. Its durability and static holding capabilities make it an essential tool in molecular biology laboratories and biopharmaceutical production pipelines, where consistent cryogenic conditions are vital.
