Liquid Nitrogen Container SHengwin 20L Aluminum Dewar Flask Carry Bag

Description

Product Overview

The SHengwin 20L liquid nitrogen container is engineered for demanding scientific and industrial environments where reliable cryogenic storage is essential. Constructed from high‑strength aerial‑level aluminum alloy, the tank features a robust shell that resists dents and corrosion while maintaining a lightweight profile for easy maneuverability. Seven layers of advanced insulation, including vacuum‑sealed panels and reflective barriers, work together to dramatically reduce heat transfer, allowing the container to retain liquid nitrogen for up to 180 days at a constant –18 °C temperature.

Precision engineering is evident in every detail of the container. The 20‑liter capacity is paired with a 50 mm caliber opening, providing ample space for large sample volumes without compromising the integrity of the stored material. The interior is lined with a polished stainless‑steel surface that prevents contamination and facilitates easy cleaning, ensuring that sensitive biological specimens remain pure throughout their storage lifecycle.

To further protect the contents, the container incorporates a double‑seal mechanism that combines an O‑ring gasket with a silicone‑based sealing ring. This dual‑seal system dramatically reduces the rate of nitrogen evaporation, extending the usable life of the liquid nitrogen and lowering operational costs. The container also includes a built‑in pressure relief valve that safely vents excess pressure, protecting both the user and the equipment during rapid temperature changes.

Accompanying the main tank are three interchangeable canisters designed to hold individual sample vials, petri dishes, or small culture plates. These canisters lock securely into the tank, providing an organized and protected environment for each specimen. A rugged, padded carry bag is supplied to shield the exterior from scratches and impacts during transport, making the system ideal for field work, mobile laboratories, and on‑site research applications.

Usage

The SHengwin liquid nitrogen container is suited for a broad spectrum of applications across animal husbandry, biomedical research, and industrial processing. In reproductive technology labs, the container serves as a dependable storage solution for semen, embryos, and oocytes, preserving viability for extended periods and supporting successful fertilization programs. Researchers in molecular biology and genetics rely on the stable low‑temperature environment to safeguard cell lines, DNA samples, and protein extracts, ensuring experimental reproducibility and data integrity.

Beyond biological specimens, the container is valuable in materials science and engineering contexts where rapid cooling or cryogenic treatment is required. It can be employed to cool metal parts for stress‑relief processes, to maintain superconducting components at operational temperatures, or to provide a cold source for cryogenic grinding and milling operations. The robust construction and secure sealing make it safe for use in high‑traffic laboratory settings, where accidental spills or temperature fluctuations could otherwise jeopardize experiments.

Portability is a key advantage for field researchers who need to collect and preserve samples on location. The included carry bag, combined with the container’s ergonomic handles, allows technicians to transport the unit safely in vehicles, aircraft, or even on foot across rugged terrain. The container’s ability to retain liquid nitrogen for months without refilling reduces logistical challenges and ensures that critical samples remain viable until they can be processed in a central laboratory.

Why Choose Us

Choosing the SHengwin 20L liquid nitrogen container means investing in a product that balances durability, performance, and cost‑effectiveness. The aluminum alloy construction offers superior strength-to‑weight ratio compared to traditional stainless‑steel tanks, making it easier to handle while still providing excellent resistance to corrosion and wear. This material choice also contributes to a lower overall price point without sacrificing the rigorous standards required for cryogenic storage.

Our commitment to quality is reflected in the meticulous manufacturing process, which includes multiple stages of inspection, vacuum testing, and thermal performance verification. Each container undergoes a 24‑hour hold test at –18 °C to confirm that the insulation system meets or exceeds industry benchmarks for boil‑off rates. This rigorous testing ensures that customers receive a product that performs reliably under real‑world conditions.

Customer support is an integral part of the SHengwin experience. Buyers receive a comprehensive user manual, safety guidelines, and access to a dedicated technical assistance line staffed by experts in cryogenic equipment. In addition, we offer a one‑year warranty covering material defects and a responsive replacement program for any components that fail to meet our high standards. This after‑sales service provides peace of mind and reinforces the long‑term value of the investment.
