Eppendorf LN2 back-up system U9044-0002

The Eppendorf LN2 back-up system U9044-0002 is a battery-driven liquid nitrogen backup designed to maintain the contents of compatible ultra low temperature freezers at preset temperatures in the event of power or refrigeration failure.

Key Features:

• Part Number: U9044-0002
• Compatible with Innova U101, U360, U535, U725, U725-G, C585, C760, CryoCube F740 series
• Operates at 120 - 220 V / 60 Hz
• Battery-driven back-up system providing temporary power to control the system during power loss
• Maintains freezer temperatures between -50 °C and -70 °C
• Requires a low-pressure liquid nitrogen storage Dewar with pressure-regulated liquid withdrawal port (Dewar not included)
• Equipped with platinum resistance thermometer probe to measure internal freezer temperature
• Includes solenoid valve, door switch, freestanding control unit, cables, transfer lines, and connectors
• Liquid nitrogen must be used to ensure proper operation
• Can be factory installed with freezer order or retrofitted on location

Advantages:

• Ensures sample preservation by maintaining ultra-low temperatures (-50 °C to -70 °C) during power failures
• Battery power allows autonomous system operation temporarily during outage
• Precise temperature monitoring and control via platinum resistance thermometer and solenoid valve increases reliability
• Compatibility with multiple Eppendorf freezer models provides flexibility in deployment
• Installation options (factory or retrofit) enable integration into existing freezer setups
• Use of liquid nitrogen enables achieving temperatures lower than what CO2 backup systems can maintain
