It features six canisters for organized sample handling and is designed for extended LN2 retention. The container’s aesthetic finish and reduced welds emphasize durability and ease of cleaning, making it suitable for laboratories, beauty clinics, and culinary labs alike. Its wide application range supports storage of semen, embryos, cells, and other LN2 applications where controlled cryogenic environments are required.
Magula 3L Liquid Nitrogen Dewar
The Magula 3L dewar emphasizes compactness with a 50 mm caliber, reducing LN2 leakage risk while offering durable aerospace-grade construction. Its lighter capacity is paired with a durable aluminum body and slow evaporation rate, making it suitable for smaller labs or mobile culinary units. The design supports wide applications across farms, research facilities, hospitals, beauty clinics, and more, providing a reliable option for controlled cooling in diverse settings.
Bonvoisin 3L Liquid Nitrogen Container
The Bonvoisin dewar is built with high-grade aerospace aluminum and vacuum insulation to ensure durability and safety. It provides six stainless steel canisters, with two holes-free for retrieving small amounts of LN2, and four with holes for sample placement. This configuration supports precise, safe sample handling in food-grade contexts, research labs, and educational kitchens, offering robust protection against leaks and temperature fluctuations.
U.S. Solid 500ml LN2 Sprayer
The U.S. Solid sprayer provides a compact option for controlled LN2 application in culinary experiments or medical demonstrations. It holds 500 ml of LN2 with a precision aluminum alloy interior canister and nine interchangeable freeze heads. Its lightweight design supports quick, targeted cooling while maintaining a safe and easy-to-use interface for operators in classrooms or kitchens.
CGOLDENWALL 20L Liquid Nitrogen Container
The CGOLDENWALL 20L LN2 container is designed for both transport and storage, supporting a broad range of biological samples and materials. It features a compact 50 mm caliber for extended storage and reduced evaporation, plus aerospace-grade aluminum construction for durability. The carry bag enhances portability, making it suitable for fieldwork, educational labs, or professional kitchens that require reliable LN2 handling on the go.
3L Liquid Nitrogen Tank (ApexscnView)
The ApexscnView 3L LN2 tank emphasizes aerospace materials and multiple insulation layers with vacuum storage. Its compact 50 mm caliber supports long-term storage with slow LN2 dissipation, aided by a polystyrene foam insert under the lid. This makes it a practical choice for small-scale laboratories, culinary demonstrations, or educational labs requiring reliable cryogenic storage for shorter durations and frequent sample access.
Buying Guide: Key Purchase Considerations
- Capacity needs: Choose a size that matches your typical sample volume and frequency of use. Larger capacities reduce refilling but increase weight and handling complexity.
- Material and insulation: Look for aerospace-grade aluminum and robust vacuum insulation to minimize nitrogen loss and maintain stable temperatures over time.
- Caliber and design: A compact 50 mm caliber often slows evaporation and reduces LN2 leakage risk. Consider whether a carry bag or transport features are important for your workflow.
- Canister configuration: Six canisters offer organized sample storage; inspect hole options for retrieval needs and sample types to ensure compatibility with your workflow.
- Portability vs. stability: If you move between locations, prioritize lighter models with protective carrying features. For stationary labs, stability and lid insulation may be more critical.
- Culinary safety considerations: When using LN2 in food applications, ensure all components meet food-grade handling standards and are cleaned according to manufacturer guidelines to prevent contamination.
- Maintenance and safety: Regularly check LN2 levels, probe for leaks, and follow safety procedures for handling frozen liquids, including proper PPE and ventilation in the workspace.
- Compatibility with accessories: If you need multiple heads, canister types, or sample retrieval accessories, verify compatibility with your preferred brand or model before purchase.
In summary, the listed containers provide a range of capacities, materials, and features designed to support safe, efficient, and versatile liquid nitrogen use in food-grade environments. Consider your application scope—culinary demonstrations, educational labs, or professional kitchens—to select a unit that best aligns with your workflow, storage needs, and safety requirements.
