Eppendorf LN2 back-up system U9044-0006

The Eppendorf LN2 back-up system (catalog no. U9044-0006) is an independent liquid-nitrogen emergency cooling module designed to protect samples in compatible Eppendorf ultra-low temperature freezers during power or system failures. The unit uses a battery-backed control and its own temperature probe to trigger pulsed LN2 injection, maintaining ultra-low temperatures and allowing either factory installation or retrofit on specified CryoCube, Premium and HEF freezers.

Key Features:

• Catalog no.: U9044-0006 — LN2 back-up system for CryoCube F570 series, CryoCube FC660 series, Premium and HEF freezers
• Electrical input: 120–220 V, 60 Hz (product listing for U9044-0006 specifies 120–220 V/60 Hz)
• Temperature capability: LN2 pulsed addition can maintain temperatures down to −85 °C (manufacturer/authorized distributor product descriptions)
• Self-contained protection: battery back-up and independent temperature probe (operates during power outage)
• Pulsed LN2 delivery to ensure even distribution while avoiding excessive coolant consumption

Advantages:

• Provides reliable emergency cooling to protect valuable samples during power or system failures via battery-backed operation
• Pulsed LN2 delivery gives more even cooling and reduces LN2 consumption compared with continuous flow
• Can be factory-installed or retrofitted to specified Eppendorf freezer models for flexible deployment
