This 3L liquid nitrogen dewar is designed for safe and efficient transfer and temporary storage of liquid nitrogen (LN2)
It features high vacuum insulation technology combined with a special anti-frost coating on the inner tank, allowing it to withstand extreme low temperatures down to -197°C without cracking or deformation
The all-stainless steel body ensures durability, while the alloy handle provides easy portability
Ideal for laboratory use, cryotherapy, biological sample transport, and small-scale industrial applications
Features:
High Vacuum Insulation: Minimizes liquid nitrogen evaporation and maintains low temperature effectively
Extreme Low-Temperature Resistance: Special anti-freeze coating on the inner chamber prevents cryogenic embrittlement and cracking
Construction: Full stainless steel body and alloy handle for long-term use
Advanced Interlayer: Polyester foam low-temperature filler + high vacuum for enhanced thermal performance
Holding Time: Approximately 6 hours under normal use (filled with LN2 and lid closed)
