Haier Biomedical Self-Pressurised Liquid Nitrogen Storage Vessels is the latest innovation for high-performance liquid phase cryopreservation. These vessels use the pressure generated from the vaporisation of a small amount of liquid nitrogen to discharge LN2 for other containers. It features a rotary ring stainless steel construction that ensures the system can withstand the most demanding environment. It provides a reduced evaporation loss rate, compared with conventional welding insulation tanks. 

Benefits

• 5 Year vacuum warranty
• Stainless steel structure
• Decant valves
• Liquid storage
• Muffler
• Pressure raising
• Relief valve
• Rotary ring construction
• Labelled valves for easy identification
• Ten models with capacities ranging from 5 to 500 litres

Product Advantages

• All models have four casters for better mobility
• Accessories included: a pressure valve, a drain valve, a relief valve, and a pressure gauge
• Extra accessories included for 200 L and above models: rupture discs and silencers
• Self-pressurised LN2 Backup System

In cases of cryofreezer failures (mechanical or power outage), the back-up system automatically injects LN2 into the freezer to maintain temperature and protect samples. The container uses the pressure generated from the vaporisation of a small amount of liquid nitrogen to discharge LN2² for other containers.
