【Aerospace-Grade Aluminum – Built to Last】 : This liquid nitrogen tank is constructed from durable aluminum alloy using advanced spinning technology. It resists impact, corrosion, and oxidation – so you get years of reliable service in demanding farm, vet, or lab environments without rust or degradation. 【Superior Vacuum Insulation – Low Evaporation】 : The integrated vacuum sealing and insulated liner minimize heat intrusion, keeping your samples cryogenically safe. With an evaporation rate of just 0.03 gallons per day, this LN2 dewar provides long‑term static storage without frequent refills – saving you time and liquid nitrogen costs. 【30L Capacity + 1.97" Caliber – Easy Access, Ample Storage】 : Hold up to 7.93 gallons (30L) of liquid nitrogen while maintaining easy sample retrieval through the practical 1.97‑inch neck opening. The compact footprint (17.56 x 26.38 inches) and portable handle make this cryogenic storage tank easy to move and store, even in tight workspaces. 【Complete Kit – Ready for Professional Use】 : Arrives with a protective sleeve to guard against bumps and a secure lock cover to reduce nitrogen loss. Simply follow the pre‑cooling instructions (add LN2, stand for 48 hours) and your nitrogen dewar is ready for immediate use – no extra parts or complicated setup. 【Trusted for Biological Preservation – Semen, Vaccines, Cells】 : Engineered specifically for critical samples. This 30L liquid nitrogen dewar is ideal for preserving animal semen, vaccines, cell lines, and other biological specimens. Essential for farms, veterinary clinics, research labs, and biobanks where sample integrity is non‑negotiable.
