- Typical capacity
- For this class of equipment, liquid nitrogen capacities typically range from 20 to 60 litres, with sample storage capacities varying based on canister and box configurations.
- Power supply
- Units of this type are passive cryogenic storage vessels and do not typically require an electrical power supply for operation, relying solely on the insulating properties to maintain temperature.
- Temperature range
- Cryogenic storage vessels commonly maintain temperatures around -196°C in the liquid phase, suitable for long-term sample preservation.
- Material construction
- Vessels are typically constructed from high-grade aluminium or stainless steel, designed for durability and optimal thermal performance.
- Evaporation rate
- Units of this type are designed for low liquid nitrogen evaporation rates, typically measured in litres per day, to maximise hold time.
- Sample access
- Access is commonly via a neck tube opening, allowing for the insertion and retrieval of canisters holding cryoboxes or cryovials.
