Magula 3L Liquid Nitrogen Dewar
The Magula 3L liquid nitrogen container features a compact 50mm caliber design to extend storage cycles while minimizing leakage. Constructed from high-strength aerospace aluminum, it offers durability and slower evaporation. The outer finish uses aviation-grade paint with fewer welds for a clean, attractive look. Its versatility supports use in farms, labs, hospitals, beauty clinics, and other units requiring dependable low-temperature storage.
U.S. Solid 3L Liquid Nitrogen Container
Designed to hold up to 3 liters of liquid nitrogen, this dewar emphasizes slow evaporation via its shape, capacity, and material construction. Evaporation rate tests are conducted by fully filling the tank and tracking nitrogen loss, ensuring predictable performance for routine storage needs in research or clinical settings.
U.S. Solid 10L Cryogenic Dewar
With a 10-liter capacity, this U.S. Solid dewar is built to store larger volumes of liquid nitrogen while maintaining a slow evaporation rate. Its robust construction supports laboratory or field storage, reducing the need for frequent refills during extended experiments or sample handling sessions.
U.S. Solid 6L Cryogenic Dewar
This 6-liter model balances compact size with substantial storage, suitable for labs and clinics that require moderate capacity with dependable temperature control. It emphasizes safe construction and a consistent evaporation profile for predictable sample handling.
CGOLDENWALL 20L Dewar LN2 Tank
The CGOLDENWALL 20L dewar provides a high-capacity option for larger storage needs. It uses lightweight aluminum alloy and vacuum insulation to maintain cryogenic temperatures. The kit includes six canisters for sample organization and a carry bag for portability, making it suitable for labs, clinics, and fieldwork where frequent access to substantial liquid nitrogen reserves is required.
Buying Guide: Key Considerations And Comparisons
When selecting a dewar liquid nitrogen container, consider the following factors to match your workflow and safety requirements:
- Capacity and use case: Choose a size that aligns with your sample volume, storage duration, and the number of samples handled per session. Smaller dewars excel in mobility; larger models maximize storage between refills.
- Material and durability: Look for aerospace-grade aluminum or similarly durable alloys for longevity and reduced evaporation. A robust vacuum-insulated design minimizes heat transfer and loss.
- Evaporation rate: A slower evaporation rate translates to longer storage times between fills. Some models are tested by filling the vessel and tracking nitrogen loss to ensure predictable performance.
- Portability and accessories: Carry bags, integrated handles, and canister sets improve transport efficiency and sample organization. Ensure included canisters match your sample types and dimensions.
- Application compatibility: Some dewars are optimized for semen, embryos, cells, or dry ice. Verify compatibility with your specific samples and storage protocols.
- Maintenance and safety: Check for secure seals, leak-proof design, and easy accessibility for safe sample retrieval. Proper handling reduces cryogenic hazards.
- Brand and warranty: Reputable manufacturers with clear warranty terms provide reliability and support for long-term lab use.
In summary, the best choice depends on your storage needs, mobility requirements, and sample type. For routine, low-volume storage with frequent movement, a compact 3L model from Magula or U.S. Solid may be ideal. For larger volumes or less frequent refilling, consider a 6L or 10L dewar, with CGOLDENWALL offering a higher-capacity option. Always prioritize a slow evaporation rate and durable construction to ensure consistent cryogenic performance across applications.
