Thermo Scientific 819 Arctic Express Cryogenic Transport Dewar for Biological Samples

The Thermo Scientific 819 Arctic Express Transport System is a cryogenic transport dewar engineered for the secure, long-term shipment of biological samples and infectious materials at liquid nitrogen temperatures. Manufactured in 2013, this reliable manual-fill LN2 Dewar features a 4.3 L capacity with a low static evaporation rate of 0.2 L/day, delivering an extended 21-day static holding time essential for biobanking and molecular diagnostics workflows.

Key technical specifications include:

• Lockable lid and internal security compartments safeguard cryovials and canisters during transport, ensuring sample integrity and protection against contamination.
• Constructed from lightweight aluminum with a pail-style handle, it facilitates easy handling and compatibility with standard carriers.
• Incorporates innovative nitrogen-absorbing material to prevent liquid nitrogen spillage, critical for maintaining biosample preservation conditions.
• Vial capacity accommodates 48 × 1.2 mL, 48 × 2 mL, 24 × 4 mL, and 16 × 5 mL cryovials, alongside a single canister supporting up to 8 canes or 120 straws, ideal for high-throughput sample storage and transport.

This cryotank is widely adopted in biotechnology, synthetic biology, and clinical diagnostics for the secure shipment of cryopreserved cultures, cellular materials, and molecular assay components. It serves as an essential tool in bioprocessing, gene editing, and biopharmaceutical production pipelines, enabling controlled cryogenic sample transport with enhanced safety features.

Suitable for researchers and laboratory professionals in biomedical engineering, cell imaging, and live-cell biobanking, the Thermo 819 Dewar combines robust construction with advanced cryogenic containment technology, supporting critical workflows in molecular cloning and synthetic biology research.
