Liquid Nitrogen Container CGOLDENWALL 3L Dewar 6 Canisters Carry Bag

Description

Product Overview

The CGOLDENWALL 3L liquid nitrogen container is engineered for scientists, technicians, and field researchers who require reliable cryogenic storage in a compact form factor. Constructed from aerospace‑grade aluminum alloy, the Dewar offers exceptional strength while maintaining a lightweight profile of just 11.35 pounds. Its 3‑liter capacity balances portability with sufficient volume for short‑term experiments, making it ideal for laboratories, teaching facilities, and on‑site sample collection.

Key specifications include a 20.5 × 11.5 × 11 inch footprint, a dual‑purpose design that supports both transportation and temporary storage, and a calibrated 50 mm caliber that minimizes liquid nitrogen loss. The container features a polished aviation‑grade finish that resists corrosion and reduces thermal conductivity, extending the hold time of liquid nitrogen. Six interchangeable canisters—five with bottom holes for specimen storage and one sealed for dipping—provide versatile handling of biological samples, reagents, or small equipment.

Usage

Designed for a wide range of environments, this Dewar excels in both controlled laboratory settings and rugged field conditions. Researchers can use it to preserve cell cultures, tissue samples, or temperature‑sensitive reagents during transport between facilities or to remote collection sites. The compact 50 mm diameter allows it to fit into standard laboratory refrigerators, while the robust aluminum construction withstands accidental bumps and drops common in field work.

Typical use cases include short‑term storage of cryopreserved specimens, preparation of low‑temperature reactions, and rapid cooling of equipment. The included carry bag simplifies mobility, enabling users to move the Dewar safely in vehicles, backpacks, or hand‑carts. Because the container is shipped empty, users can fill it with locally sourced liquid nitrogen, ensuring cost‑effective operation and compliance with local safety regulations.

Why Choose Us

CGOLDENWALL leverages decades of experience in cryogenic technology to deliver a product that combines performance, durability, and user‑centric design. The aluminum alloy body undergoes an optimized production process that reduces welds, applies aviation‑grade paint, and incorporates precision machining for a seamless finish. This attention to detail translates into a slower evaporation rate, meaning users can rely on longer hold times without frequent refilling.

Quality assurance is integral to every unit. Each Dewar undergoes rigorous testing for leak integrity, thermal performance, and mechanical resilience. The six canisters are manufactured to exacting tolerances, ensuring a secure fit and consistent temperature distribution across all stored items. Additionally, CGOLDENWALL provides responsive customer support, offering guidance on safe handling, maintenance, and troubleshooting to maximize the lifespan of the container.

FAQ

What is the expected hold time for liquid nitrogen in this Dewar?

When fully filled and sealed, the 3 L CGOLDENWALL Dewar typically maintains liquid nitrogen for 8‑10 hours under normal ambient conditions, thanks to its insulated aluminum alloy construction.

Can the container be used with other cryogenic liquids?

While optimized for liquid nitrogen, the Dewar can safely hold other cryogenic liquids such as liquid argon or liquid helium, provided users follow appropriate safety guidelines and verify compatibility.

How do I clean the canisters after use?

After each use, rinse the canisters with distilled water and allow them to air‑dry. For thorough cleaning, a mild detergent solution can be used, followed by a final rinse to remove any residues.

Is the Dewar compatible with standard cryogenic storage racks?

Yes, the Dewar’s dimensions conform to common laboratory rack specifications, allowing it to be securely placed in standard cryogenic storage systems.

What safety precautions should I observe when handling liquid nitrogen?

Always wear insulated gloves, safety goggles, and protective clothing. Ensure the Dewar is placed in a well‑ventilated area to prevent nitrogen buildup, and never seal the container completely while the liquid nitrogen is still boiling.
