Medical Liquid Nitrogen

A cryogenic liquid is a liquefied gas which has a boiling point below 150℃

• Liquid Oxygen -183.0°C (boiling temp at 101.325 kPa)
• Liquid Argon -185.9°C
• Liquid Nitrogen -195.8°C
• Liquid Helium -268.9°C

The most common cryogenic liquids are: Cryogenic liquids convert to gas quickly when being decanted

Small volumes of cryogenic liquids are stored and handled in purpose built storage vessels. The two types utilised by Air Liquide customers are;

Pressurised Liquid Vessels (PLVs)

• Contain cryogenic liquid under pressure
• Greatest capacity for liquid
• Filled by trained operators of Air Liquide

Dewars

• Non-pressurised storage vessels
• Insulated containers with lids that can vent
• Typically filled by PLVs by end users
