What are you using instead of an LN2 dewar right now?
Ultra-low temperature (ULT) freezers
Typically set at around -80°C, these freezers are common for many biological samples. However, they don’t achieve the same ultra-low temperatures as liquid nitrogen (-196°C), which is sometimes necessary for highly sensitive or long-term preservation needs
Dry ice storage
Dry ice can maintain temperatures of about -78°C, which is lower than a typical freezer but still far above LN₂ temperatures. It’s also more prone to supply issues and can be cumbersome or costly over the long term.
Alternative cryogenic options
Some labs might rely on specialized cryo shipping containers or outsource cryogenic storage to external facilities, especially if they have low-volume or infrequent needs.

Choosing the right liquid nitrogen dewar
Selecting the ideal LN₂ dewar depends on your lab’s specific needs, workflow, and growth plans. Here are four key considerations to guide your decision.
1. Capacity & hold time
- Match your volume requirements. Estimate the daily or weekly liquid nitrogen usage and factor in how often you’ll need to refill.
- Plan for peaks. If your lab’s workload spikes for certain projects, ensure the dewar can handle the extra demand without frequent top-offs.
2. Mobility & ergonomics
- Physical constraints. If your lab involves moving dewars between stations or floors, choose a design with sturdy handles, wheels, or easy-lift features.
- User-focused design. Ergonomic components reduce strain on technicians and lower the risk of accidents or spillage.
3. Monitoring & safety features
- Level gauges & alarms. Built-in systems let you track nitrogen levels at a glance, preventing unexpected runouts.
- Pressure relief valves. Safeguard against over-pressurization and comply with safety standards.
4. Construction & insulation
- High-quality materials. Stainless steel or aluminum builds offer enhanced durability and corrosion resistance.
- Efficient insulation. Superior vacuum layers extend hold times and minimize evaporation, cutting down on LN2 costs over the long run.
By focusing on capacity, design, safety features, and insulation, you can choose a liquid nitrogen dewar that’s perfectly aligned with your lab’s immediate needs and future ambitions.

Liquid nitrogen dewar frequently asked questions
Estimate how much LN2 you use daily or weekly. Factor in peak demand and choose a dewar that can accommodate those volumes without frequent refills.
It depends on the dewar’s insulation and capacity. High-quality dewars can maintain LN2 for days or weeks, but frequent opening or large neck openings reduce hold time.
Use a transfer hose or funnel from a larger LN2 source. Wear appropriate PPE (face shield, gloves) and fill slowly to avoid splashing or rapid vapor release.
Secure the dewar upright in a well-ventilated vehicle or cart. Use safety straps to prevent tipping and ensure the vent isn’t blocked, as LN2 needs room to vent safely.
Yes, if you follow proper protocols. Always wear cryogenic gloves, goggles or face shield, and ensure good ventilation to prevent nitrogen gas buildup.
Many dewars have built-in gauges or dipsticks. Check levels regularly, and consider models with alarms or digital monitors for added safety.
Stainless steel is often more durable but heavier. Aluminum is lighter and sometimes easier to move. Both can be well-insulated, so choose based on handling needs.
First, allow it to warm up and evaporate any remaining LN2. Then wipe with a lint-free cloth or mild cleaning solution if necessary. Avoid harsh chemicals and ensure the dewar is thoroughly dry before refilling.
Regularly inspect for dents or compromised insulation, check vacuum integrity, and ensure the lid or neck is sealing properly. Replace worn parts like gaskets as needed.
Absolutely. LN2 dewars are versatile for sample storage, cryo-processing, and instrument cooling. Just confirm capacity and temperature specs align with each application.
Follow OSHA or local regulations on cryogen handling, maintain proper ventilation, keep safety gear accessible, and document LN2 usage and maintenance.
Look for increasing LN2 loss, damaged insulation, or vacuum failure. If you’re refilling more often or handling more samples than before, an upgrade may save time and costs.
Limit lid openings, keep the dewar in a cool area, and ensure the neck/lid is sealed properly after each use. Good insulation and minimal exposure to ambient air are key.
