U.S. Solid 10L LN2 Tank With Canisters
The 10-liter U.S. Solid cryogenic dewar is designed to store liquid nitrogen with a slower evaporation rate, helping minimize loss during transport. This model includes six canisters and a carrying bag, enhancing portability for fieldwork or on-site demonstrations. The dewars’ shape and material construction focus on safety and durability in cold-temperature conditions, supporting reliable LN2 handling for laboratory or veterinary applications.
U.S. Solid 6L Cryogenic LN2 Tank
This six-liter dewar emphasizes compact portability while maintaining LN2 containment. It includes a six-canister setup and a carrying bag, making it suitable for smaller transport tasks or mobile applications where space is limited. The container is designed to minimize nitrogen loss through optimized insulation and construction suitable for repeated use in field or clinic environments.
VEVOR 30 L Liquid Nitrogen Tank
The VEVOR 30-liter LN2 tank combines a lightweight aluminum alloy body with vacuum insulation to reduce heat transfer and extend sample storage time. It includes six canisters and a carry bag with straps, supporting extended transport needs for larger sample sets in laboratories or beauty-industry settings. The design prioritizes ease of handling without compromising safety at cryogenic temperatures.
Bonvoisin 10L LN2 Container
Bonvoisin’s 10-liter liquid nitrogen container emphasizes durability with reinforced aeronautical aluminum construction and vacuum insulation. The unit ships with six stainless steel canisters, including a mix of canisters with and without holes for controlled sampling and retrieval. The design supports long-term storage and safer transport for semen, embryos, or other cryogenic specimens.
CGOLDENWALL 20L LN2 Container
The CGOLDENWALL 20-liter dewars combines aerospace-grade aluminum with multilayer insulation and a 50 mm caliber for efficient LN2 storage. It comes with a carry bag and six canisters, including two without holes for precise nitrogen retrieval and four with holes for sample storage. This configuration aims to balance capacity and accessibility for medium-scale transport tasks in research or clinical settings.
Buying Guide
- Capacity and use case: Choose capacity to match typical transport loads—smaller 3–6 L units for quick moves, 10 L for intermediate needs, or 20–30 L for larger sample sets.
- Insulation and evaporation: Look for vacuum insulation and materials designed to minimize LN2 evaporation during transport to reduce loss and handling frequency.
- Canisters and retrieval: A system with multiple canisters—some with holes and some without—offers flexible access to samples while maintaining temperature.
- Portability: Carriage bags, straps, and lightweight aluminum alloys improve handling, especially in clinics, labs, or field sites.
- Durability and safety: Aeronautical-grade aluminum or other strong alloys, along with robust fittings, enhance durability and reduce risk of leaks.
- Maintenance and cleaning: Materials should be corrosion-resistant and easy to clean between uses to support sanitary handling of samples.
- Intended environment: For beauty, semen preservation, or scientific applications, ensure the container’s design supports sterile handling and sample integrity.
- Cost of ownership: Consider evaporation rate and durability to gauge long-term value beyond upfront price.
For best results, align your choice with how often you transport LN2, how many samples you handle at once, and the required balance between portability and capacity. Always follow manufacturer guidance for safe operation, storage, and transfer procedures.
