Why choose a specific laboratory freezer?
A laboratory freezer is designed to ensure a constant temperature, generally much lower than that of conventional 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 breakdown or abnormal temperature variation.
Unlike conventional freezers, they are capable of reaching temperatures from -20°C to -86°C, essential for the preservation of sensitive cell cultures, tissues, DNA, enzymes or vaccines.
Types of laboratory freezers available
Upright freezers
Perfect for optimizing floor space, they are equipped with multiple compartments for easy storage and access to samples.
Chest freezers
They generally offer better temperature homogeneity, ideal for long-term storage of large quantities of samples.
Ultra-freezers (-86°C)
Used for the preservation of biological samples at very low temperatures, they guarantee the absolute stability necessary 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 : essential to avoid sample degradation.
- Temperature alarm : essential to be alerted in the event of an anomaly.
- Energy consumption : some A++ energy class models offer an excellent compromise between performance and economy.
- Type of cold : ventilated to avoid the formation of frost, or static for certain specific applications.
- Useful 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 conservation:
- Do not overload the compartments to ensure even air circulation.
- Check door seals regularly to prevent heat loss.
- Systematically record temperatures using a dedicated recorder.
- Schedule regular preventative maintenance to check the compressor, thermostat and sensors.
Proper maintenance extends the life of your laboratory freezer and keeps your sensitive samples safe.
Laboratory freezer and complementarity with other equipment
A high-performance laboratory cannot rely on a single piece of equipment. In addition to storage, preparation and analysis are equally essential. For example, to isolate biological samples before freezing, a laboratory centrifuge is essential. This type of combination maximizes the quality and reproducibility of your experiments.
Selection criteria for a first purchase
The intended volume and use
Determine whether you need massive storage (chest) or easy access (vertical cabinet).
The opening frequency
A laboratory that frequently handles samples will prefer a ventilated cold model to avoid the formation of frost.
Temperature accuracy
Molecular biology or cryopreservation applications require a high-performance ultra-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 allows it to meet the stringent requirements of research, medical biology, pharmaceutical, and chemical industry laboratories. In addition, some models have alarms in case of temperature fluctuations or power outages, for maximum protection of stored contents.
Benefits of a Reconditioned Laboratory Freezer
Opting for a refurbished laboratory freezer has several advantages. First, the cost is significantly lower than that of new equipment, without compromising on performance thanks to a rigorous refurbishment process. At Rewake, each device is checked, calibrated, and brought up to standard to ensure optimal reliability. Second, it's an environmentally friendly approach that supports the circular economy, while reducing acquisition times: refurbished equipment is often available immediately. Finally, you benefit from the expertise of scientific equipment specialists, with dedicated after-sales service and solid guarantees.
Purchase laboratory freezer
To successfully purchase a laboratory freezer, several criteria must be considered. Storage capacity, temperature range, cooling type (static or ventilated), and onboard safety systems are essential to choosing the right model for your business. Rewake offers a demanding selection of reconditioned equipment, including upright freezers , ultra-low temperature chests, and specific models for cryopreservation. Whether you are a university, pharmaceutical, or industrial laboratory, our expertise will help you find 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 technology, capacity, and features. A standard model can cost between €1,500 and €4,000, while a new ultra-low temperature freezer can cost up to €10,000. Thanks to its refurbished offering, Rewake makes it possible to acquire this equipment at much more affordable prices, while maintaining a high level of quality and performance. This represents a valuable opportunity for organizations looking to optimize their budget without compromising the safety of their samples.
