Why choose a specific laboratory freezer?
A laboratory freezer is designed to ensure a constant temperature, generally much lower than that of standard domestic freezers. It offers:
- Thermal stability even during repeated door openings.
- A precise control system to avoid harmful fluctuations.
- An alarm in the event of a power failure or abnormal temperature variation.
Unlike standard freezers, they are capable of reaching temperatures from -20°C to -86°C, which are essential for the preservation of cell cultures, tissues, DNA, enzymes, or sensitive vaccines.
Types of laboratory freezers available
Upright freezers
Perfect for optimizing floor space, they are equipped with multiple compartments that facilitate storage and access to samples.
Chest freezers
They generally offer better temperature uniformity, which is ideal for long-term storage of large quantities of samples.
Ultra-low temperature freezers (-86°C)
Used for the preservation of biological samples at very low temperatures, they guarantee the absolute stability required for certain sensitive research.
Key features of a good laboratory freezer
To make the right choice, several criteria must be taken into account:
-
Thermal stability: imperative to prevent sample degradation.
-
Temperature alarm: essential for being alerted in case of an anomaly.
-
Energy consumption: some A++ energy class models offer an excellent compromise between performance and economy.
-
Type of cooling: ventilated to prevent frost formation, or static for certain specific applications.
-
Usable volume: it must be sized according to the nature and quantity of samples to be stored.
How to optimize the use of your laboratory freezer?
To ensure optimal preservation:
- Do not overload the compartments to ensure homogeneous air circulation.
- Regularly check the door seals to avoid any thermal loss.
- Systematically record temperatures using a dedicated recorder.
- Plan for regular preventive maintenance to check the compressor, thermostat, and sensors.
Proper maintenance extends the lifespan of your laboratory freezer and secures your sensitive samples.
Laboratory freezer and complementarity with other equipment
A high-performance laboratory cannot rely on just one piece of equipment. In addition to storage, preparation and analysis are just as essential. For example, to isolate biological samples before freezing, a laboratory centrifuge is indispensable. This type of combination maximizes the quality and reproducibility of your experiments.
Selection criteria for a first purchase
The volume and intended use
Determine if you need massive storage (chest) or easy access (upright cabinet).
The frequency of opening
A laboratory that handles samples frequently will prefer a ventilated cooling model to avoid frost formation.
Temperature precision
Molecular biology or cryopreservation applications require a high-performance ultra-low temperature freezer.

Using a laboratory freezer
The laboratory freezer is designed to ensure optimal preservation of biological samples, chemical reagents, and many other sensitive materials. Unlike domestic freezers, it offers precise temperature control, often adjustable between -10°C and -86°C depending on the model. This meets the strict requirements of research, medical biology, pharmaceutical, and chemical industry laboratories. Furthermore, some models have alarms for temperature variations or power outages, providing maximum protection for the stored contents.
Advantages of a refurbished laboratory freezer
Opting for a refurbished laboratory freezer has several advantages. Firstly, the cost is significantly lower than that of new equipment, without compromising performance thanks to a rigorous refurbishment process. At Rewake, each device is checked, calibrated, and brought up to standards to ensure optimal reliability. Secondly, it is an ecological approach that supports the circular economy while reducing acquisition lead times: refurbished equipment is often available immediately. Finally, you benefit from the expertise of scientific equipment specialists, with dedicated after-sales service and solid warranties.
Laboratory freezer purchase
To succeed in purchasing a laboratory freezer, several criteria must be taken into account. Storage capacity, temperature range, cooling type (static or ventilated), and onboard safety systems are essential for choosing the model suited to your activity. Rewake offers a demanding selection of refurbished equipment, including upright freezers, ultra-low temperature chest freezers, and specific models for cryopreservation. Whether you are a university, pharmaceutical, or industrial laboratory, our expertise will guide you in finding the solution best suited to your needs at the best value for money.
Laboratory freezer price
The price of a laboratory freezer varies considerably depending on the technology, capacity, and features. A standard model can cost between €1,500 and €4,000, while an ultra-low temperature freezer can reach €10,000 when new. Thanks to refurbishment, Rewake makes it possible to acquire this equipment at much more accessible rates while maintaining a high level of quality and performance. This represents a valuable opportunity for organizations wishing to optimize their budget without compromising the security of their samples.
