CryoCube® F440 Series – ULT Freezer

The Eppendorf CryoCube F440 series of ULT freezers (also known as ultra-low temperature freezer/-80 °C freezer) is based on a strong compressor for fast recovery to -80 °C after opening. As this class of freezer is often used as real lab freezer, multiple openings per day are normal – a dynamic and strong cooling system is mandatory for fast recovery to -80 °C after every freezer access: Provide your valuable samples a safe and cold location. The freezer minimises operating costs by low energy consumption per day while providing superior protection for your critical samples.

How can I choose the right ULT freezer in a 400 – 500 L/300 – 350 freezer box scale for my lab? Where do I need to pay attention to get a reliable -80 °C freezer?

The Eppendorf CryoCube F440 series offers a 5-compartment lay-out and 5 insulated inner doors for easy sample access and safe sample storage at -80 °C. The walls are 130 mm thick based on foam and vacuum insulation panels (for the “h” version).
The ULT freezer has a volume of 440 L (15.5 cubic feet) and a temperature range from -50 °C to -86 °C. The CryoCube F440 series is based on two different freezer models:

CryoCube F440n:
• 130 mm wall (polyurethane insulation)
• “Green” hydrocarbon-based cooling liquids (R290/ R170)
• Air-cooling

CryoCube F440h:
• 130 mm wall (polyurethane insulation and vacuum insulation panels)
• “Green” hydrocarbon-based cooling liquids (R290/ R170)
• Air-cooling

Features of the CryoCube F440 Series

• Volume: 440 L (15.5 ft³), e.g. up to 32,000 samples
• Efficient insulation, composed of traditional insulation (“n”-version) and vacuum insulation panels (“h”-version), saves energy
• Efficient compressor control system reduces cycle times to lower energy consumption and increases freezer longevity
• Automatic vent port on front door of upright CryoCube models improves energy consumption and enables fast sample access
• Lockable main switch to prevent switch-offs by accident
