CryoCube® F740

CryoCube® F740

Design the freezer around the sample: The Eppendorf CryoCube® F740 series is the latest addition to the Eppendorf Freezer family. Combining the high-quality tradition of our previous freezers with an increased capacity, the CryoCube F740 is designed to store more of your samples securely while maintaining optimal energy usage. The integration of the PhysioCare Concept during development means that the CryoCube F740 is easier and more comfortable to use, supports an ergonomic workspace, and provides optimal workflow in the lab.

Product Information

Eppendorf ULT Freezers are known for their energy efficiency, reliability, and worry-free, long-term sample preservation. They provide many of the same basic features as our Innova ULT Freezers and high-efficient ULT freezers. The polyurethane foam insulation (incl. vacuum insuation panels for CryoCube F740) combined with a highly efficient cooling system achieve and maintain ultra-low temperatures of -86 °C.

Expanded options for enhanced security: The following models of the CryoCube F740 series are available, you can select the best fit for your needs:
F740 with LED interface, classic cooling liquids, and air-cooling
F740i with touchscreen interface, classic cooling liquids, and air-cooling
F740iw with touchscreen interface, classic cooling liquids, and water-cooling
F740hi with touchscreen interface, green cooling liquids, and air-cooling
F740hiw with touchscreen interface, green cooling liquids, and water-cooling

Need for special set-up?

All units are available as 3-compartment or 5-compartment instrument. The 3-compartment unit has 3 shelves (fixed bottom one + two removable shelves). The 5-compartment unit has 5 shelves (fixed bottom one + 4 removable shelves).
The air-cooled versions offer a left-handed or right-handed outer door handle as option to adapt the freezer to the conditions in your lab.
The built-in inverter technology enables the same freezer to be used on 100, 115, 208, and 230 V, just change the power cable.

Focusing on sustainability?

The "h" versions are the green flagships - by using hydrocarbon-based cooling liquids (R290/ R170), the power consumption is further reduced compared to non-"h" versions.

Bothered by loud ULT freezers?

The CryoCube F740 has an improved sound level of 47.8 dB. The "i" versions provide you some silence level of down to 41.3 dB. These "i" versions are equipped with a sound-reduction-system. Based on a different air filter position at the front of the freezer, the air flow is now guided in a more silent way towards the ventilation system. At the backside of the freezer, a special compartment further reduces the sound level. Relax when working near a CryoCube F740i.

Burdened by unsorted boxes cluttering your freezer?

Make your scientific life easier: Store your freezer storage boxes within organized freezer racks. The CryoCube F740 series offers two different ways to store boxes: The 3-compartment and the 5-compartment style. The maximum of 576 boxes can be stored in a 3-compartment CryoCube F740, equipped with MAX racks.For other racking systems, please check the inner dimensions of the freezer and contact Eppendorf.

Worried about the safety of your high value samples within your ULT freezer?

The "i" versions are equipped with a touchscreen interface where data are stored on-board and can be checked 24/7. If necessary, data as well as service reports can be extracted by a front-mounted USB port. The electronic lock system enables controlleded access and higher sample safety.The handling concept is based on ou longterm expertise of Eppendorf PhysioCare combined with extensive user test sessions.
