How to select a -80 °C freezer for my lab?

Sample storage in the lab is not limited to the freezer. The process of sample storage includes the right selection of vessels, a reliable labeling/ identification of your samples, robust freezer boxes and racks, a convenient sample management tool, the freezer itself, and freezer performance monitoring systems.
Still, the freezer is the core of your sample storage system:
Eppendorf offers different lines of -80 °C lab freezers to meet a variety of needs. Depending on the approach, there are different questions to answer before you select your Ultra-Low-Temperature freezer, also known as ULT freezer to store your freezer boxes and your valuable samples:

Do you need an upright freezer or a chest freezer to store your freezer boxes?
Do you want a foam-insulated freezer wall enforced by vacuum insulation panels or is foam sufficient?
Which footprint in the lab is sufficient and/ or acceptable?
When choosing an upright freezer, do you need a 3- or 5-compartment instrument?
Do you need a future-proof freezer with green cooling liquids as R290/ R170?
Do you want to connect your ULT freezer?

As your ULT freezer is a longterm investment, a careful planning and validation is recommended.We want to provide you with high performance, sample safety, and convenience.

It’s 2 a.m. in the morning & and the phone rings...

»There is an alarm in your lab, you‘d better come over…«
Due to the 50,000 valuable samples in your freezer, you rushed to the lab. Finally, the temperature was still ok, false alarm but you were done for the day. Just imagine, you get an alarm notification of VisioNize by email about your freezer, and in the next step, you log into the system and check online the temperature graph and the events of your freezer – still being at home. Then, you can still decide if you have to go to the lab or if you still have some hours - or if it is again a false alarm.

Your freezer becomes a smart storage with VisioNize keeping your valuable samples safe. VisioNize offers you the possibility to remotely monitor your freezer. Take advantage of customizable notifications to meet your needs. More peace of mind for "You and Your Lab" with VisioNize.

Important note:
Depending on your country, VisioNize and the VisioNize services may not be available. You can either check the Eppendorf eShop or contact your Eppendorf sales representative for details.

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 Eppendorf freezer. Many ULT 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.

Reduce air conditioning power consumption 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

Annoyed by uncomfortable handling?

Ergonomics is far beyond the »ergonomically designed chair«. Eppendorf started to optimize the laboratory devices regarding ergonomics already 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 is broaden up to include further laboratory products as a holistic solution to harmonize the workflow in your laboratory with your health and well-being, e.g. for the Eppendorf ULT freezer:

Intuitive interface for easy handling
Automatic vent port for easy re-access to samples
Low noise level for convenient working conditions
Ergonomic door handle for easy opening and closing
All cable interfaces are located at one corner for convenient access

More about the Eppendorf PhysioCare Concept

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.

Cost of ownership

When investing in a new freezer, the product price itself is only one aspect. Others include the long-term costs of power consumption and the costs of service and spare parts. Keep in mind, a high-quality freezer will do its job in the lab for 10 years or more.

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.
eLabInventory is a sample management software.

Eppendorf offers three lines of freezers to meet a variety of needs:

The Eppendorf High-Efficiency ULT Freezers are one of the best energy-efficient freezers in the market. The vacuum insulation panel technology is the core: an advanced thermal insulation technology that significantly outperforms traditional materials such as closed-cell foams (urethane), foam beads, and fiber blankets. Vacuum insulation removes gasses within the insulating space to reduce heat transfer; as a result, thermal insulation performance far exceeds traditional materials. Other freezers use vacuum insulation panel technology, but none use Vacupor NT®.

Vacupor panels not only provide exceptional thermal insulation, they have a metal-coated polymer film barrier seal to maintain vacuum and they are composed of biodegradable, CFC-free, and HCFC-free materials.
The Eppendorf Innova® ULT Freezers combine ultra-efficient insulation panels with foam insulation, generating a maximized storage capacity.
The Eppendorf ULT Freezers have established a reputation for preserving outstanding sample quality while minimizing energy consumption.

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 sample need to be safe: When the freezer door has been opened, you expect a fast recovery back to -80°C. Efficient cooling is 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

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 doors

Out part for sustainability

Eppendorf constantly validates and improves production processes for a better sustainability footprint.
