Magula 10L Liquid Nitrogen Container
The Magula 10L LN2 dewar uses a compact 50 mm caliber to minimize liquid nitrogen loss during storage and transfer. It employs aerospace-grade aluminum for durability and a slower evaporation rate, with an appealing exterior finish. Six canisters are included for versatile sample handling. This option is best for small to medium volumes in laboratories, veterinary clinics, or beauty clinics that require reliable short- to mid-term preservation. A potential limitation is that higher-volume or long-term storage may necessitate a larger capacity unit.
ApexscnView 20L Liquid Nitrogen Tank
The ApexscnView 20L dewar combines aerospace-grade aluminum with a multi-layer insulation design and internal vacuum storage to extend sample life. Its 50 mm caliber keeps evaporation relatively slow, aided by a polystyrene foam insert under the lid. This unit is well-suited for facilities that need longer storage cycles and a robust, high-capacity transport option. It may be heavier to carry than smaller dewars, which is a consideration for field use.
Magula 3L Liquid Nitrogen Dewar
The Magula 3L dewar offers a compact, lightweight option with a 50 mm caliber designed to minimize evaporation. Constructed from aerospace-grade aluminum, it emphasizes durability and a slow evaporation rate suitable for small clinics or laboratories with tight space. Best for individual researchers or clinicians needing quick access to LN2 in a compact form. Avoid this if long-term, large-volume storage is required.
U.S. Solid 20 L Cryogenic Dewar
The U.S. Solid 20 L dewar is designed to hold up to 20 liters with an emphasis on slow evaporation. It provides a solid balance of capacity and practicality for mid-to-large scale preservation needs. A potential limitation is that exact evaporation performance is influenced by fill level and handling; regular monitoring is advised for precise scheduling of transfers.
CGOLDENWALL 20L Liquid Nitrogen Container
The CGOLDENWALL 20L LN2 container emphasizes a wide application range, including semen, embryos, cells, and other samples. It uses a compact 50 mm caliber for reduced evaporation and includes a carry bag for transport. Aerospace-grade aluminum enhances durability. A consideration is that, for very large-volume operations, multiple units may be needed to maintain continuous supplies during lengthy experiments.
Treasea 20L Liquid Nitrogen Container
The Treasea 20L dewar features a 1.97-inch neck, six canisters, and a carry bag. It is designed for reliable long-term storage of larger sample sets such as cells, tissues, or embryos. It blends durability with practical storage options and quick access capabilities. Consider this option when handling frequent transfers across larger sample sets; otherwise a smaller unit might suffice.
Buying Guide
What capacity should you choose?
Capacity depends on sample throughput and transfer frequency. Choose 3–10 L for individual usage or small clinics. Opt for 20 L for laboratories with higher daily sample needs or semen/embryo storage.
Which design features matter?
- Caliber (neck diameter): A compact 50 mm caliber reduces evaporation and aids long-term storage.
- Insulation: Vacuum multi-layer insulation extends storage time and minimizes heat transfer.
- Canister system: Six canisters offer versatile storage and quick access to different samples.
- Material: Aerospace-grade aluminum delivers durability and corrosion resistance.
What about portability and handling?
- Carry bags and strap options improve transportability for on-site work or field use.
- Weight and balance matter for safe carrying between rooms or vehicles.
How to manage evaporation?
Keep the liquid nitrogen level above the preservation material and monitor fill levels regularly. Avoid overfilling, and ensure proper lid insulation to minimize evaporation during routine handling.
FAQ
- What is a LN2 dewar designed for?
It is designed to store and transport liquid nitrogen with reduced evaporation and safe access to samples.
- Why choose a 20 L dewar over a 10 L one?
For higher sample throughput or longer-term storage without frequent refills.
- What is the significance of a 50 mm caliber?
A smaller neck helps minimize nitrogen loss during transfers.
- Are six canisters standard?
Six canisters provide flexible storage for multiple sample types; some models offer sealed canisters for different access needs.
- Is aluminum the best material?
Aerospace-grade aluminum blends strength, corrosion resistance, and lighter weight for easier transport.
- How should I maintain LN2 dewars?
Regularly check LN2 levels, ensure proper lid fit, and follow manufacturer storage guidelines to maximize longevity.
