Worried about your sample safety?

The most important aspect of long-term sample storage is safety. The CryoCube F570 series of freezers is equipped with reliable heavy-duty compressors (2-stage cascade cooling system). Quick pull-down times enable fast re-use after cleaning/defrosting of the instrument. The freezers have short recovery times after opening to provide extra sample safety (Door-Open-Recovery/DOR) when getting back to -80 °C.
The temperature range of this ULT freezer series is from -50 °C to -86 °C. Most users put the set point to -80 °C.
The automatic vent port enables fast re-access if needed.
For even higher sample safety, the ULT freezers can be equipped with CO2/LN2 back-up systems and a chart recorder. Temperature monitor systems can be used to monitor the freezers remotely.

Burdened by unsorted boxes cluttering your freezer?

Make your scientific life easier: Store your freezer storage boxes within organized freezer racks. The CryoCube F570 series offers a 5-compartment model as a standard. The compartments can be height-adapted if necessary. A maximum of 25 freezer racks can be stored (5 racks per compartment). The racks can be filled with 4 boxes per drawer/layer, resulting in a maximum storage of 400 freezer boxes (53 mm/2 in) which can be stored in this ULT freezer.
You can choose between metal racks made of aluminum or stainless steel. Decide if you prefer side access or drawer racks.
For convenient rack selection, take advantage of the Eppendorf rack selection tool:
Selection tool for Eppendorf racks (please use Mozilla FireFox)
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 Eppendorf eLABInventory software

Which factors influence the sustainability of a freezer?

Sustainability for ULT freezers is a challenge: Maintaining extremely low temperatures of -80 °C or even -86 °C for 24 hours a day, 7 days a week requires energy.
The stored samples need to be safe: When the freezer door has been opened, you expect a fast recovery back to -80 °C. Efficient cooling requires energy as well as powerful compressor systems.
There are multiple factors influencing the energy consumption of a lab freezer for ultra-low temperatures:
› Thickness of insulation
› Type of insulation
› Type of cooling liquids
› Efficiency of compressors
› Control of compressor
› Pressure in cooling system
› Style of cooling loops (diameter, length, density, ...)
› Sealings of outer door
› Sealings of inner doors
› Insulation of inner doors
› Insulation of outer door

External validation and certification

By following our epGreen concept, the Eppendorf freezer R&D team developed intelligent solutions where energy savings are combined with durable long-lasting product quality and ergonomic aspects. By using highly efficient technologies, the CryoCube F570h lab freezer has a very low power consumption value. This future-oriented instrument class provides consumption levels which are ahead of most competitors within this volume class.
Our performance data are based on an external validation agency where three units of the freezer model are tested.
Besides this, the CryoCube F570h and the F570n are certified by the ACT label of My Green Lab as well as by ENERGY STAR®.

Hydrocarbons – green cooling of the future

In 2014, the European Union announced a ban of all non-hydrocarbon-liquids (EU_517/2014) until 2020. This ban includes all cooling devices except instruments for temperatures below -50 °C. Based on this exception, ULT freezers for -86 °C can continue to run with non-hydrocarbon cooling liquids like HFCs. However, it also makes sense to replace the HFC cooling liquids for ULTs as global warming needs to be slowed down.
Which cooling liquids can be used as a green alternative? Hydrocarbons are also known as green or natural gases. The two major representatives for cooling purposes are propane and ethane (known as R290 and R170). Based on IEC 60335-2-89, no additional safety instructions for using green gases in ULT freezers are necessary.
Due to this goal, we at Eppendorf clearly plan to replace all classic cooling ULT freezers in our portfolio within the next years.

Remember 2008?

As one of the very first advocates of green gases at -86 °C, Eppendorf now has more than 12 years of experience in R&D, production, logistics, and service in the field.
In 2008, the (Eppendorf) New Brunswick Premium U570h was one of the very first commercially available ULT freezers driven by green cooling liquids.

Air-conditioning at the limit? Go for water-cooling
You can improve the conditions and comfort in your lab while saving energy by installing a water-cooled ULT freezer. Many of these lab freezers use the air in the laboratory to extract heat energy from the freezer’s heat exchanger. Another option is to use a water-cooled ULT freezer connected to a facility’s recirculating water system. A constant stream of water removes the heat from the heat exchanger, rather than the ambient air in the lab.
What are the benefits of water-cooling for ULT freezers?
› Reduce air conditioning power consumption within the room where your freezer is located by letting the water carry away the heat
› The heated cooling water can be reused for other heat-demanding systems in the facility
System specifications:
› Minimum flow: 29 L/h
› Inlet pressure: 1 – 10 bar
› Temperature range of water: 7 °C to 25 °C

PhysioCare® – ergonomics for my freezer?

Ergonomics goes far beyond the »ergonomically designed chair«. Eppendorf already started to optimize the ergonomics of laboratory devices in the early 1970s. In 2003, we started the PhysioCare Concept, focusing on ergonomic liquid handling devices like our pipettes.
Nowadays, the Eppendorf PhysioCare Concept has been extended to include further laboratory products to provide a holistic solution to harmonize the workflow in your laboratory with your health and well-being.
Examples for Eppendorf ULT freezers include:
› Intuitive interface for easy handling
› Automatic vent port for easy re-access to samples
› Low noise level for pleasant working conditions
› Ergonomic door handle for easy opening and closing
› All cable interfaces are located at one corner for convenient access

Ergonomics in daily work

The main focus of our ULT freezer door handle is to provide you the best ergonomics we can design. Especially the new door handle of the CryoCube models is based on the Eppendorf PhysioCare Concept®: Safe grip but very light forces are needed to open and close the freezer door.

Sample identification needed?

Sorting samples in freezer boxes and freezer racks is the first level of improved storage efficiency. Correct and stable labeling is your next level: The SafeCode system provides prelabeled, barcoded vessels with 3-level coding in multiple formats to safeguard your samples and improve your processes.
Eppendorf DataPort provides all relevant vessel information for complete documentation such as certificates, lot number, drawings, and order number, all online.
Manage your barcoded samples with sample management software like eLABJournal.

Lost in samples? Stay organized!

Over many years, you collect hundreds and thousands of samples – samples that are the results of years of hard work – samples of high value. When storing these in the ULT freezer at -80°C, it is vital to keep them safe and accessible.
Many scientists still use spreadsheets or even paper-based lists to keep track of their storage. While these solutions may work most of the time, they are susceptible to human error, damage, and misplacement.
Keep track of your samples with eLabInventory
