U.S. Solid 20L Cryogenic LN2 Dewar Tank
The 20-liter U.S. Solid cryogenic dewar is designed for bulk LN2 storage and sample management. Its 125 mm neck diameter improves accessibility for retrieving specimens, while the dewar construction aims to minimize nitrogen loss over time. This model emphasizes a balanced evaporation rate and robust build to support longer storage between fills. The included six canisters and a carry bag enhance on-site handling and transport between workstations or field locations.
U.S. Solid 10L Liquid Nitrogen Dewar
This 10-liter dewar provides a compact option for smaller labs or mobile tasks. It is built to hold LN2 with a focus on a slower evaporation rate, helping to extend storage time between refills. The design emphasizes practicality for routine semen storage, sample transport, or short-term cryogenic storage, with reliable insulation and a durable exterior suitable for recurring use in busy work environments.
NANBEI 10L LN2 Tank
NANBEI’s 10-liter LN2 tank focuses on durability and transportability. It uses robust insulation to maintain ultra-low temperatures and comes with sturdy handles to facilitate movement. This option is suitable for laboratories needing a middle-ground capacity with reliable performance for extended sample storage and safe handling during transfers or fieldwork.
Bonvoisin 3L LN2 Dewar
Bonvoisin’s 3-liter dewar is a compact, versatile option designed for semen, embryos, cells, and dry ice storage. It uses high-grade aluminum with vacuum insulation and includes six canisters, with two without holes for precise samples and four with holes for holding larger materials. The design emphasizes safety, durability, and organized storage in smaller laboratory environments or clinics.
3L Liquid Nitrogen Tank by ApexscnView
ApexscnView offers a compact 3-liter dewar with aerospace-grade aluminum construction and a detailed design to minimize evaporation. The aluminum body provides strength, while insulation and a sealed interior help maintain LN2 temperatures. The tank ships with six canisters and a carry bag, making it suitable for clinics and research settings that require portable, reliable LN2 storage in a smaller footprint.
VEVOR 3L LN2 Tank
VEVOR’s 3-liter tank prioritizes portability and reliability with a multi-layer vacuum insulation system. It includes six canisters and a carry bag with straps, making it convenient for technicians who require quick access to samples or assets during fieldwork, beauty industry applications, or research settings. The design balances lightweight handling with durable construction to prevent leaks and temperature drift.
Buying Guide: Key Considerations For Choosing A Liquid Nitrogen Dewar
- Capacity needs: Choose a size that aligns with your sample volume, frequency of LN2 usage, and storage space. Larger dewars reduce evaporation-related losses but require more handling space.
- Insulation and evaporation rate: Multi-layer insulation and a well-sealed design minimize LN2 loss. Compare tested evaporation rates where available to estimate how long LN2 will last between fills.
- Durability and materials: Look for aluminum alloys or other cryo-rated materials that resist impact and maintain cryogenic integrity. Vacuum insulation helps maintain ultra-low temperatures.
- Portability and accessories: Carry bags, straps, and integrated canisters enhance transport and organization. Ensure the neck diameter and opening suit your sample types for easy access.
- Canister configuration: A mix of canisters with and without holes supports versatile sample access and retrieval, important for clinics or labs with varied workflows.
- Maintenance and safety: Check for leak prevention features, robust seals, and clear user manuals. Proper handling reduces the risk of LN2 exposure and spills.
- Compatibility with applications: Some tanks are optimized for semen storage, biological specimens, or cosmetic/beauty industry uses. Ensure the model fits your specific storage needs.
- Transport considerations: For fieldwork or mobile labs, a compact, well-insulated unit with a carry bag improves usability and reduces spill risk.
Across these options, users should balance capacity, portability, and stability to meet their storage and handling requirements. The selections above provide a spectrum from compact 3-liter dewars to larger 20-liter models, all designed to maintain LN2 at ultra-low temperatures while facilitating safe retrieval and sample management.
