Eppendorf – Ultra-low Temperature Freezers

CryoCube® F570 Series - ULT Freezer

The Eppendorf CryoCube F570 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 opening. Provide your valuable samples a safe and cold location. The freezer minimizes operating costs 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 (“h” versions). Benefit from sustainable cold storage combined with safe sample storage.

How can I choose the right ULT freezer in a 500 – 600 L/400 freezer box scale for my lab?

The Eppendorf CryoCube F570 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 represents the volume class of 570 L (20.1 cubic feet) and a temperature range from -50 °C to -86 °C. The CryoCube F570 series is based on three different freezer models:

CryoCube F570n:
• 130 mm wall (polyurethane insulation)
• “Green” hydrocarbon-based cooling liquids (R290/ R170)
• Air-cooling

CryoCube F570h:
• 130 mm wall (polyurethane insulation and vacuum insulation panels)
• “Green” hydrocarbon-based cooling liquids (R290/ R170)
• Air-cooling

CryoCube F570hw:
• 130 mm wall (polyurethane insulation and vacuum insulation panels)
• “Green” hydrocarbon-based cooling liquids (R290/ R170) for 230 V
• Water-cooling

Key features  of the Eppendorf CryoCube F570 ULT freezer series:

• Easy sample access: The Eppendorf CryoCube F570 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).
• Sustainable footprint: 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, certified by ENERGY STAR^®.
• Increased sample safety storage: 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.

CryoCube® F101h - ULT Freezer

When it comes to maximizing sample storage capacity at the bench, the Eppendorf CryoCube F101h ULT freezer sets the standard: Up to 6,000 vessels below your bench in the lab with real -80°C. By taking advantage of ultra-efficient, compact vacuum insulation panels which are used in combination with traditional PU foam insulation, we slim down the freezer wall thickness from 130 mm to 80 mm.
The footprint is limited to half a square meter, especially designed for small labs. The temperature range for this -80°C lab freezer is between -50 °C and -86 °C.

Features of the CryoCube F101h

• Vacuum insulation panels allow for increased internal capacity with the same footprint as traditionally foamed freezers
• Inner doors are gasketed as well as insulated creating 2 separate compartments minimizing cold air loss while you access your samples
• Easy-to-read LED control panel and alarm status
• Special vacuum vent with plunger ergonomically located to gain immediate access to your freezer
• Inner doors can be quickly removed without the need for tools for easier and faster defrosting
• Full stainless steel interior for easy cleaning during maintenance and defrost cycles; powder-coated steel exterior
• Special low-temperature outer door seals allow gaskets to remain flexible at –86 °C and prevent ice buildup for easy access to samples
• Password protection of alarm and temperature setpoints to prevent unauthorized setting changes

CryoCube F101h applications

• ULT freezers are suitable for storage and preservation of all types of biological materials/samples:
  • Bacteria
  • Cells
  • Spores
  • Pollens
  • Protozoa
  • Blood components
  • DNA
  • Tissue used in research only
  • Preservation of chemicals or material testing components for a longer period.

CryoCube® F440 Series - ULT Freezer

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 minimises operating costs by low energy consumption per day while providing superior protection for your critical samples.

How can I choose the right ULT freezer in a 400 – 500 L/300 – 350 freezer box scale for my lab? Where do I need to pay attention to get a reliable -80 °C freezer?
