A liquid nitrogen dewar is an insulated storage container designed to maintain liquid nitrogen at -196°C for long-term storage. It uses vacuum insulation technology (similar to a thermos bottle) to minimise heat loss and evaporation. Dewars are essential equipment for IVF clinics, research laboratories, and fertility centres that need to preserve biological samples indefinitely.
Key features:
- Double-walled construction with vacuum insulation
- Maintains -196°C indefinitely
- Available in sizes from 10L to 200L+
- Lifespan of 10-15 years with proper maintenance
- Certified to UK/ISO safety standards
