Thermo 819 LN2 Dewar Cryogenic Sample Transport with 4.3L Capacity

The Thermo 819 LN2 Dewar is a manual fill cryogenic transport vessel designed specifically for the secure shipping and storage of biological samples and infectious materials at cryogenic temperatures. Constructed from lightweight aluminum with a pail-style handle, this portable container supports biotechnological workflows requiring safe liquid nitrogen storage and transport.

Key technical features include:

• Capacity: 4.3 liters of liquid nitrogen, supporting long-term static sample preservation.
• Static Holding Time: Up to 21 days of liquid nitrogen retention with an evaporation rate of 0.2 L/day, critical for uninterrupted cold chain logistics in molecular diagnostics and bioprocessing.
• Sample Capacity: Compatible with 1 canister holding up to 8 canes, 6 vials per cane (1.2 mL), and 120 straws; vial capacities include 48×1.2 mL, 48×2 mL, 24×4 mL, and 16×5 mL, providing flexible sample organization options.
• Safety and Security: Features a lockable lid that prevents liquid nitrogen spillage and sample contamination, ensuring specimen integrity during air or ground shipment.
• Design: Aluminum body with spill-prevention materials absorbs excess nitrogen to reduce risks, while the ergonomic handle facilitates transport in clinical diagnostics, cell imaging labs, and biomanufacturing environments.
• Dimensions and Weight: Lightweight at 1.09 kg (2.4 lbs) with compact shipping dimensions (24.4 × 24.4 × 42.7 cm), optimizing its use in constrained laboratory workflows.

This dewar is widely adopted in synthetic biology research and biotech production pipelines where maintaining cryogenic conditions during transport is essential. It is ideal for applications in molecular cloning workflows, live-cell preservation, and long-term storage of sensitive biological samples.
