I am looking into buying a new ULT freezer but I do not know if I should buy an upright or chest model?
Eppendorf sells both upright as well as chest model freezers. The key features to consider for your purchase are availability of space and ease of access. Upright freezers have a lower footprint than chest models and it is easier to access samples more frequently. Whereas the chest models offer more capacity at a higher footprint, making them ideal for long term storage with higher temperature uniformity.
What is the difference between 120V, 60 Hz and 208/220V, 60 Hz?
Both are available in the US and in general 120V is considered as the household voltage and 208/230V is considered as the industrial voltage. 120 V has a slightly higher power consumption due to the lower voltage. There is no difference in the power consumption or performance between the 208 V and 230 V. Depending on the power receptacle you currently use at the planned location for the freezer, please be sure to select the correct power cable. We recommend a dedicated circuit for each freezer.
Why is a lockable switch plate needed?
The lockable switch plate protects the device from being switched on off accidentally.
A separate battery circle can be switched off during transport.
What does "warm up time" mean?
This is the time required for a unit to warm up in case of a power or system failure from -80°C to 0°C. This usually takes more then 20 hours for the smallest Eppendorf freezer F101h and around 40 h for Eppendorf CryoCubes with 2/3 filling. The warm up data for all Eppendorf freezers can be requested at local Sales office
What is Vacuum panel technology?
Vacuum insulation panels are used in Eppendorf Innova, HEF (high efficiency) and most CryoCube freezers for maximum storage and maximum energy savings by providing more effective thermal insulation than traditional foams.
What is the function of an auto vent port ?
When freezer door is opened ambient air rushes into the freezer. When the door is closed, this air is compressed and a vacuum is created. Eppendorf freezers are equipped with an auto vent port on the left hand or integrated in the front panel (CryoCube) to equalize the pressure. This operates automatically but can be used manually by pressing the button in addition for quicker access.
How do I defrost my Eppendorf – 86 °C ULT freezer?
After extended period operation, defrosting may become necessary. Please refer to your Eppendorf freezer manual for step by step direction on how to defrost the unit.
What does a CO2 or LN2 Backup System provide?
The Backup Systems are independent systems which provide protection of samples in case of a power or unit failure by injecting liquid LN2 or CO2 into the unit. It is controlled by an independent temperature sensor. Carbon dioxide systems will maintain temperatures between -40 °C and -70 °C for a period of up to 48 hours. Liquid nitrogen back-up systems will maintain the freezer temperature at -86 °C for few hours. CO2 and LN2 systems can be retrofitted by the Service.
Can I connect the freezer to my building management system (BMS)?
All Eppendorf freezers are provided with an alarm monitoring socket at the rear of the freezer and a matching plug. The device can be connected to a central monitoring system (building management system) for freezer alarm monitoring. Eppendorf also offers an independent chart recorder.
What is the material of the inner chamber?
All Eppendorf ULT Freezer provide stainless steel chambers without rust build up, scratches and easy cleanability.
Can the ULT freezers be placed in a room with ambient temperature of 4 °C?
This is not possible. Our Freezers are specified to operate in ambient temperatures between 10°C and 32°C.
Which options are available for the new Eppendorf CryoCube F740 series?
All CryoCube F740 types are available as left hand or right hand option. A 3 or 5 compartment version is offered but each version has 3 inner doors.
What are the benefits of the advanced interface (Touch screen) on F740 hi/i ?
The benefits are easy intuitive operation, home screen showing setpoint, ambient temprature, temperature graph and event list.
The event list saves all important events like door openings, all kind of alarms, warning limits, change of settings.
All logging and Service data can be downloaded via USB Stick.
For monitoring of Freezers and additional Eppendorf devices, VisioNize Software can be installed for remote control.
How is the sample access controlled?
Sample access is managed with the help of an electronic lock that works in combination with an active user managememt. The administrator is able set up users with different rights and levels. The user / some user groups have access to the samples and rights to acknowledge alarms and change settings.
What is the most cost-effective model of the F740 series?
The F740h shows the well-known LED Display and is insulated with PU Foam and Vacuum insulation panels. It has the same high quality as F740hi regarding construction of chamber and robustness of machine.
Which refrigerants are used in different models and which is the most environmental friendly ULT?
For F740h and F740hi we use the most environmental friendly hydrocarbon refrigerants (R290/R170) in a two stage cooling system with very low energy consumption data for the F740hi of 10.5 kWh/d at- 80C and 9.0 kWh/d at -70C.
Is there a sample management system available?
With the help of BioItech inventory software solution it is easy to stay organized. For more information please click here
Are the F740 devices noisy?
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.
Which racking systems and accessories are available ?
Eppendorf offers a broad range of Stainless steel and Aluminium Racks for sample storage. In addition Eppendorf Storage Boxes of polypropylene are available in 2"", 2.5"", 3"",4"" and 5"" sizes for standard Cryovessels, SafeLock tubes, 5ml Eppendorf tubes, 15 and 50 ml conical tubes, PCR plates, Deepwell plates and MTPs.

Yes, the CryoCube F740h (box enabled) can be connected to VisioNize Lab Suite via a Gateway box. It enables remote monitoring and status checks, alert notifications form anywhere.
What are the height requirements when placing the CryoCube F101h under a work bench?
The external dimensions are 83 x 90 x 56.6 cm (HxDxB).
The work bench should allow for a clearence of at least 85 cm, measured from the bottom edge of the bench to the bottom floor.
What kind of cooling liquids are used for the CryoCube F101h?
The cooling system operates with "green" cooling liquids (R290/ R170) only.
In 2014, the European Union announced a ban of all non-hydrocarbon-liquids (EU_517/2014) until 2020 (also known as "F-gas regulation"). Hydrocarbons are also known as green or natural gases. The two major representatives are propane and ethane (known as R290 and R170). This ban includes all cooling devices except instruments for temperatures below -50°C. Based on this exception, ULT freezers of -86°C can continue to run with HFCs. Still, it makes sense to replace the HFC cooling liquids also for ULTs as global warming needs to be slowed down.
What kind of racks are available for CryoCube F101h?
CryoCube F101h freezers have 2 internal compartments, each of which can hold three racks.
All rack options for different vessel formats are listed in the brochure "Store More".
Is the CryoCube F101h provided with inner doors?
The chamber is divided by 2 inner doors sealing the two internal compartments.
The inner doors are equipped with seals to minimize the loss of cold when opening.
What material is used for the inner chamber of the CryoCube F101h?
The inner chamber of CryoCube F101h, like all other Eppendorf ultra-low temperature freezers, is made of stainless steel and is therefore resistant to a large number of disinfectants, scratches and rust.
Can the CryoCube F101h be locked with a key?
Yes, a lock is integrated in the door handle of the CryoCube F101h. Two keys are available.
Where do I find the control panel of the CryoCube F101h?
The control panel of the CryoCube F101h is located in the upper right corner on front of the device.
What kind of insulation is used for the CryoCube F101h?
The Freezer is insulated using polyurethane foam (PU) as well as vacuum insulation panels. This results in a low energy consumption of the F101h and leads to long warm-up time during power failure.
