Air Liquide TR11 nitrogen Vessel

• Long-term cryogenic storage of biological samples such as cells, tissues, and DNA.
• Laboratory research requiring stable ultra-low temperature environments.
• Storage of pharmaceutical and biotechnological products sensitive to temperature fluctuations.
• Industrial applications where controlled cryogenic conditions are necessary for material preservation.

Typical capacity

For this class of equipment, capacities commonly range from 10 to 50 litres of liquid nitrogen.

Power supply

Cryogenic storage vessels like the TR11 are typically passive, requiring no external power for temperature maintenance, only for optional monitoring systems.

Temperature range

Units of this type maintain temperatures around -196°C, the boiling point of liquid nitrogen.

Material construction

Commonly constructed from durable aluminium alloy for the outer casing and inner vessel, with a vacuum insulation layer.

Holding time

Typical static holding times for similar vessels can range from several weeks to a few months, depending on capacity and usage.

Sample storage format

Designed to accommodate various storage formats, including cryovials, blood bags, and canes within racks or boxes.

• What maintenance does a liquid nitrogen vessel require?

  Maintenance typically involves regular visual inspections for damage, monitoring liquid nitrogen levels, and occasional cleaning. Periodic recalibration of any integrated monitoring systems may also be required.

• How is the liquid nitrogen refilled?

• What safety precautions are necessary when operating this equipment?

• Can this vessel be moved easily?

• What is the expected lifespan of a used liquid nitrogen vessel?

Liquid nitrogen storage systems are valued for reliable long-term sample preservation in research and pharmaceutical settings. Buyers typically prioritise checking insulation condition, vapour loss rates, and maintenance history when purchasing used units. Industry sentiment emphasises the importance of verifying calibration records and safety certifications before installation. Common strengths include robust construction and compatibility with existing laboratory infrastructure. Capacity requirements and storage location should guide selection, as should supplier support for ongoing servicing and spare parts availability.
