Worthington D050-8C00 Liquid Nitrogen Withdrawal System
The Worthington D050-8C00 system enables safe and efficient handling of liquid nitrogen for larger dewars. It supports smooth filling, venting, and transferring processes. The device is designed for high-volume use, with a discharge rate up to 8 L/min at 10 psi, helping laboratories maintain steady workflows. A two-year guarantee provides additional assurance for operational reliability in demanding environments.
U.S. Solid 10L Cryogenic Container LN2 Tank
This 10-liter dewar by U.S. Solid emphasizes storage efficiency with a design that minimizes nitrogen evaporation. The unit is purpose-built for holding extremely cold liquids like LN2, combining the right shape, capacity, and material construction to sustain longer storage periods. Evaporation rate testing is part of its quality assurance, ensuring predictable performance in lab or field settings.
Magula 10L Liquid Nitrogen Container
The Magula 10L dewar combines aerospace aluminum construction with a compact diameter to reduce leakage risks while offering a slower evaporation rate. Its 6 canisters enable organized storage and rapid retrieval of samples or LN2, making it suitable for clinics, laboratories, and educational facilities. The carry bag enhances portability between workstations or field sites.
VEVOR 20 L Liquid Nitrogen Tank
VEVOR’s 20-liter tank prioritizes portability and robust insulation. Made from aviation-grade aluminum, it reduces scratches and deformation while delivering reliable, low-temperature performance. The 6 canisters, with two without holes for precise extraction and four with holes for sample storage, support a flexible workflow in beauty clinics, research labs, and semen preservation contexts.
CXRCY 10L Cryogenic Dewar
The CXRCY 10L dewar emphasizes a dual-use design for transportation and storage. Its vacuum insulation and polyurethane neck plug reduce nitrogen volatilization, helping to maintain low temperatures over extended periods. The set includes a 6-canister arrangement and carry bag, making it suitable for labs, beauty facilities, and agricultural research where reliable LN2 handling is essential.
Buying Guide: Key Considerations For Selecting Liquid Nitrogen Dewars
Capacity and evaporation rate: Larger dewars store more LN2 but may evaporate faster if insulation is insufficient. For busy labs, prioritize models with proven slow evaporation and high-insulation design.
Insulation quality: Vacuum-insulated double-wall construction minimizes heat transfer. Look for multi-layer insulation and high-grade materials like aerospace aluminum for durability and longevity.
Portability: Weighing options from compact 3–10 L units to 20–25 L systems affects usage in clinics or fieldwork. Carry bags and straps enhance mobility between stations or sites.
Canister configuration: Dewars with multiple canisters enable organized storage, quick access, and controlled sampling. Check the number of canisters and whether some are hole-free for precise extraction.
Durability and warranty: Aluminum alloy construction and robust fittings reduce damage risks in transport and daily handling. A manufacturer warranty adds assurance against early failures in high-use environments.
Safety features: Consider devices that support safe filling, venting, and transfer. A reliable withdrawal or transfer system reduces splash risk and exposure to LN2.
Cost of ownership: While initial price matters, evaluate long-term operating costs, replacement parts, and potential downtime due to evaporation or leaks.
