*KeyFeatures *Lightweight and Durable Material: The liquid nitrogen tank is crafted from high-strength aviation-grade aluminum alloy, ensuring both portability and durability. This material effectively protects the stored liquid nitrogen and prevents scratches and deformation, ensuring safety and reliability during use. *Vacuum Insulation Design: Surrounding the liquid nitrogen container with a multi-layer insulation structure and special gas adsorbents creates an excellent vacuum storage space. This minimizes heat transfer, maintaining a stable low-temperature environment inside the container and extending the storage time of samples. *6 Canisters: Our liquid nitrogen dewar is equipped with 6 canisters, including 2 without holes for precise nitrogen extraction and 4 with holes for storing samples, allowing users to quickly access or replace stored materials as needed. *Portable Carry Bag: The protective cover prevents scratches and damage from accidental impacts, and adds an extra layer of protection. It's also easier to transport and carry, ensuring the cryogenic tank can be safely transported to laboratories, hospitals, or any other necessary location. *Wide Applications: The LN2 container is widely used in laboratories, medical institutions, farms, beauty salons, and more. They can safely store a variety of samples, including semen, embryos, cells, dry ice, and metal materials, meeting diverse needs from biological research to industrial applications. ******************************************************************************************************* *Specifications Item Model Number: YDS-20 Capacity: 5.28 gal / 20L Hole Diameter of Mouth: 1.96 in / 5 cm Outer Dimensions of Container: ∅15.1 x 26.4 in / ∅38.4 x 67.0 cm Canisters Quantity: 6pcs(2 without holes&4 with holes) Static Preservation Time: 165~172 days Daily Evaporation: 90~110 g/D Product Dimensions: 15.1 x 15.1 x 26.4 in / 384 x 384 x 670 mm Net Weight: 21.8 lbs / 9.9 kg ******************************************************************************************************* *Pakcage Content 1 x Liquid Nitrogen Tank 1 x User Manual 1 x Protective Cover 6 x Canisters
