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 minimizes operating costs by low energy consumption per day while providing superior protection for your critical samples. A combined insulation based on vacuum insulation panels and polyurethane foam enables extremely low energy consumption during long-term storage for the CryoCube F440h.

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.
