Western Enterprises Cryogenic Transfer Hose WMH-2-14
The WMH-2-14 hose offers clean oxygen service compatibility and exceptional flexibility, making it suitable for transferring liquid nitrogen in lab and industrial contexts. Its resistance to kinking helps maintain a steady flow, reducing interruptions during LN2 transfers. Machined CGA stainless steel end connections provide robust sealing and compatibility with standard cryogenic fittings. This hose is designed to support precise LN2 handling while limiting heat pickup during transfer, which helps minimize evaporation losses and improves overall efficiency in LN2 workflows.
U.S. Solid 10L Cryogenic Container LN2 Tank
The 10-liter U.S. Solid LN2 Dewar emphasizes a design geared toward slower evaporation and safer long-term storage. Dewars are tailored to hold extremely cold liquids like liquid nitrogen, and the container’s shape and materials aim to minimize heat ingress. Evaporation rate testing is a key factor in selecting a dewar for applications requiring predictable LN2 retention over extended periods, such as educational demonstrations, sample storage, or basic research setups. The included straps and canister configuration enhance portability and organization of stored samples.
VEVOR 20 L Liquid Nitrogen Tank with 6 Canisters
VEVOR’s 20-liter LN2 tank combines portability with robust insulation. The aluminum alloy construction balances durability with lighter weight, making handling easier in busy lab environments. Its multi-layer insulation and vacuum design reduce heat transfer, helping extend sample storage times. Six canisters, including two without holes for retrieving small samples and four with holes for storing multiple specimens, support organized, quick access to stored materials. The bag and carry options further enhance portability for field or mobile labs.
CXRCY 10L Aluminum Cryogenic Dewar
CXRCY’s 10-liter aluminum cryogenic dewar emphasizes dual utility for transportation and storage. Its insulation and vacuum design, with a low-thermal-conductivity neck tube and polyurethane neck plug, slow LNG volatilization and preserve ultra-low temperatures for extended periods. This Dewar is suitable for laboratories, agricultural technology applications, and beauty industry contexts where stable LN2 storage is critical. The durable construction aims to withstand repeated use, while the canister system allows flexible sample management.
NANBEI 3L Liquid Nitrogen Tank
The NANBEI 3-liter LN2 tank is designed for compact, portable LN2 storage with solid insulation to maintain ultra-low temperatures. Its compact design, paired with sturdy handles, facilitates easy transport for on-site sampling and rapid transfers in clinics or research facilities. The YDS-3 container supports safe, controlled access to LN2 and is suitable for beauty industry needs, semen preservation, and other cryogenic applications requiring a smaller volume with dependable insulation.
Buying Guide
- Capacity and evaporation rate: Choose tanks and dewars with the right capacity for your workflow and consider evaporation rates to minimize LN2 losses during storage or transfer.
- Insulation and design: Vacuum-insulated dewars reduce heat ingress. Look for two-layer constructions, polyurethane neck plugs, and low-thermal-conductivity neck tubes for long-term stability.
- Material and durability: Aluminum alloys provide a balance of lightness and durability, while stainless steel fittings ensure reliable seals. Inspect canister configurations and the mounting for easy access and safe handling.
- Portability: If you need to move LN2 between rooms or to field sites, prioritize lighter dewars, carry bags, straps, and ergonomic handles. Consider the overall weight when full.
- Canister system: A six-canister arrangement is common, with variations including holes for sample storage and holes-free sections for retrieving material. Ensure the layout matches your sample handling needs.
- Hose quality and compatibility: For LN2 transfer, select hoses with clean oxygen service, flexible construction, and robust end connections to ensure a stable flow and minimize kinking.
- Safety and handling: Always adhere to cryogenic safety guidelines. Inspect seals, fittings, and insulation regularly, and store dewars upright in a stable, ventilated area.
- Use-case alignment: If your work requires frequent sample retrieval, prioritize hoses with easy access to fittings and canister designs that support quick sample changes without excessive heat exposure.
