CryoCube® F740 series

Design the freezer around the sample
The Eppendorf CryoCube® F740 series is the latest addition to the Eppendorf ULT 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 enables an optimal workflow in the lab.

Expanded options for enhanced security: The following models of the CryoCube F740 series ULT freezers are available, you can select the best fit for your needs:

› CryoCube F740h: 80 mm wall (polyurethane foam and vacuum insulation panels), LED interface, "green" cooling liquids (R290/ R170), and air-cooling
› CryoCube F740hi: 80 mm wall (polyurethane foam and vacuum insulation panels), touchscreen interface, "green" cooling liquids (R290/ R170), and air-cooling
› CryoCube F740hiw: 80 mm wall (polyurethane foam and vacuum insulation panels), touchscreen interface, "green" cooling liquids (R290/ R170), and water-cooling

All -80 lab freezer versions of the CryoCube F740 series have a volume of 740 L (26.1 square feet) and a temperature range from -50 °C to -86 °C.

Eppendorf ULT Freezers are known for their energy efficiency, reliability, and worry-free, long-term sample preservation.

Worried about the safety of valuable samples in 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 controlled access and higher sample safety.
This handling concept is based on our long-term expertise from Eppendorf PhysioCare combined with extensive user test sessions.
The CryoCube F740 series is equipped with reliable heavy-duty compressors (2-stage cascade cooling system). Quick pull-down times (250 min) enable fast re-use after cleaning/defrosting of the instrument. The freezers have short recovery times after opening to provide extra sample safety.
For even higher sample safety, the ULT freezers can be equipped with CO2/LN2 back-up systems and a chart recorder (Type II). Temperature monitor systems can be used to monitor the freezers remotely.

Bothered by loud ULT freezers?
The CryoCube F740h has an improved sound level of 47.8 dB. The "i" versions provide you some silence level of even 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 back of the freezer, a special compartment further reduces the sound level. Relax when working near a CryoCube F740 "i" version.

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. A maximum of 576 boxes can be stored in a 3-compartment CryoCube F740 series equipped with MAX racks or 504 boxes equipped with standard racks. The 5-compartment CryoCube F740 series can be used for up to 528 boxes.
For other racking systems, please check the inner dimensions of the freezer and contact Eppendorf.
Additionally, you might think about a sample management solution beyond sample location documentation by paper or spreadsheet. Check out eLABInventory software.

Need a special set-up?
All units are available with 3 or 5 compartments. 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 an 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 classic cooling systems.
CryoCube F740 models are also validated by the ACT concept of "My Green lab".
The CryoCube F740hi and F740hiw are certified by ENERGY STAR®.
