Description
Premium Liquid Nitrogen Container (Dewar Flask)
The Premium Liquid Nitrogen Container is a high-efficiency, ultra-insulated cryogenic vessel engineered for the safe storage, long-term preservation, and transport of liquid nitrogen ($LN_2$). Utilizing advanced high-vacuum multi-layer insulation technology, this industrial-grade Dewar flask is essential for livestock breeding (semen storage), medical laboratories, biotechnology research, and culinary arts, offering exceptionally low evaporation rates and superior thermal performance.
Key Features & Benefits
1. Advanced High-Vacuum Multi-Layer Insulation
Constructed with a double-walled structure, the container features an ultra-high vacuum zone packed with multi-layer thermal insulation materials. This structural design minimizes heat transfer via radiation, conduction, and convection, ensuring that the liquid nitrogen remains at its boiling point of -196°C with minimal daily evaporation loss.
2. High-Strength, Aviation-Grade Aluminum Alloy
The outer shell and internal liner are manufactured from premium, lightweight aviation-grade aluminum alloy. This material selection delivers exceptional structural durability, corrosion resistance, and high-impact protection while keeping the empty weight low for comfortable manual handling.
3. Open Storage System (Without Internal Dividers)
Designed for maximum space utilization and storage flexibility, this model features a spacious internal chamber without fixed metal dividers, brackets, or compartment slots. This completely open interior allows laboratory technicians and field operators to store larger canister sizes, bulk cryogenic vials, large biological samples, or specialized materials without configuration restrictions.
4. Ergonomic Neck Plug & Thermal Protective Cover
The vessel is equipped with a custom-molded, high-density polyurethane neck plug that fits tightly into the tube opening, providing an airtight thermal seal while still allowing necessary trace gas venting to prevent pressure buildup. Each unit comes standard with a heavy-duty, padded protective jacket with shoulder straps to shield the canister from scratches and impacts during transport.
