What is a laboratory refrigerator-freezer combination?
A laboratory refrigerator-freezer combination is a piece of equipment that integrates two distinct, independently regulated compartments. The refrigerator compartment maintains a positive temperature, generally between 2 and 8°C, suitable for storing reagents, culture media, and heat-sensitive biological samples. The freezer compartment reaches negative temperatures, down to -30°C depending on the model, for the long-term storage of samples and frozen products.
This equipment is fundamentally different from consumer combinations due to the precision of its thermal regulation, the resistance of its interior materials to chemicals, and its compliance with the requirements of pharmaceutical and biological environments. A consumer model does not guarantee the thermal stability or traceability required by laboratory protocols.
The uses covered are varied: storage of vaccines and heat-sensitive medications, preservation of reagents and buffers, freezing of biological samples for biobanking, and maintaining culture media at a controlled temperature between uses.

The different types of refrigerator-freezer combinations available
The Rewake collection covers the main families of refrigerator-freezer combinations used in laboratories. Each type meets specific volume, thermal precision, and usage level constraints. Identifying the right model from the start avoids selection errors and the risk of product loss.
Useful volumes range from a few tens of liters for compact benchtop models to several hundred liters for high-capacity equipment. The type of cooling and the temperature range of the freezer compartment are the two priority criteria to evaluate according to the products to be stored.
Standard laboratory refrigerator-freezer combination
The standard combination is the benchmark model for analysis and research laboratories. It integrates two independent compartments with precise temperature regulation, height-adjustable shelves to adapt the interior to the formats of the containers used, and interior LED lighting to facilitate product location.
Its noise level is suitable for shared workspaces. It is suitable for the daily storage of reagents, buffers, culture media, and biological samples. The useful volume of each compartment, the temperature range, and the precision of the thermostat are the key criteria to check according to the laboratory's protocols.
Ventilated cooling combination and high-capacity combination
The ventilated cooling combination ensures optimal thermal homogeneity inside each compartment thanks to forced cold air circulation. It eliminates uneven temperature zones and prevents frost formation on stored products, making it particularly suitable for applications sensitive to thermal variations.
High-capacity models are sized for biobanks, pharmaceutical units, and production laboratories storing large volumes of products simultaneously. Their energy consumption and footprint must be taken into account during installation, particularly in terms of room ventilation and available electrical power.
Technical criteria for choosing your laboratory refrigerator-freezer combination
The first criterion is the useful volume of each compartment, expressed in liters. It must correspond to the actual volume of products stored simultaneously, with sufficient margin to ensure good cold air circulation and avoid overloading. Overloaded equipment loses thermal homogeneity and storage efficiency.
The temperature ranges of the two compartments must cover all requirements of the laboratory protocols. The type of cooling, static or ventilated, conditions the thermal homogeneity and frost formation. Thermostat precision is particularly critical for pharmaceutical or biological products whose storage is regulated.
The presence of a thermal deviation alarm is essential for laboratories subject to traceability requirements. It allows for the detection of any cold chain break and intervention before products are compromised. Some models integrate a data logger to document temperatures over time.
The noise level, energy class, and dimensions of the equipment are practical criteria to check according to the installation environment. Compliance with the pharmaceutical standards applicable to the site is a point to validate with your quality manager before acquisition.
Rewake reconditioned refrigerator-freezer combinations: our refurbishment process
Each refrigerator-freezer combination added to the Rewake collection follows a structured refurbishment protocol, performed by technicians specialized in laboratory equipment. The objective is to restore thermal performance in compliance with original specifications at a reduced acquisition cost.
The first step is a complete inspection of the compressor and the refrigeration circuit. The condition of the refrigerant, condenser, and evaporator is checked for any leaks, wear, or operational anomalies. Any degraded component is replaced before performance tests are conducted.
Door seals are checked and replaced if necessary to ensure the tightness of each compartment. The actual temperature range is measured at several setpoints in both compartments. The values obtained are compared to the equipment's original specifications.
The thermostat, alarms, and all controls are tested under real conditions. The interior of the compartments is cleaned and disinfected before shipment. Each piece of equipment comes with a warranty and complete traceability, including the temperatures measured during validation tests.
For which uses and sectors?
The refrigerator-freezer combinations in the Rewake collection cover a wide spectrum of professional applications. In microbiology and cell biology, they are used for the daily storage of culture media, bacterial strains, enzymes, and reagents sensitive to heat or freezing.
The pharmaceutical industry and biotechnology firms use this equipment for the storage of biological raw materials, vaccines, and heat-sensitive medications for which the cold chain must be rigorously maintained and documented. Temperature traceability is a non-negotiable regulatory requirement here.
Biobanks and clinical research laboratories use the freezer compartments for the long-term storage of human or animal biological samples. Thermal stability and the long-term reliability of the compressor are priority criteria for these applications where the loss of a sample is irreversible.
Agri-food quality control and hospital care units complete the spectrum of sectors covered. In these environments, the availability of spare parts and the responsiveness of after-sales service are criteria to be integrated into the choice of equipment.
Why choose a reconditioned refrigerator-freezer combination?
The main argument is economic. A reconditioned refrigerator-freezer combination is accessible at a significantly lower price than an equivalent new piece of equipment. For laboratories managing tight budgets or equipping several storage stations simultaneously, it is a concrete lever for cost reduction without compromising thermal stability or reliability.
Major brands of laboratory refrigeration are represented in the Rewake collection. Accessing equipment recognized for its robustness and thermal precision, at a controlled cost, is a direct advantage for teams subject to strict storage requirements.
Delivery times are generally shorter than for new orders, as the equipment is available in stock and ready to ship. An urgent replacement after a breakdown or a quick extension of cold storage capacity thus becomes possible without tying up a significant investment budget.
Environmentally, extending the life of refrigeration equipment reduces manufacturing needs and limits electronic waste. Refurbishment contributes to better overall energy efficiency of the laboratory's equipment fleet without compromising the operational quality of the delivered device.

FAQ — Reconditioned refrigerator-freezer combination
What is the difference between a laboratory refrigerator-freezer combination and a consumer model?
A laboratory model offers precise and stable thermal regulation in each compartment, with deviation alarms and temperature traceability adapted to regulatory requirements. The interior materials are resistant to chemicals commonly found in laboratories. A consumer model is designed for food storage, without these levels of precision or documentation. The two pieces of equipment are not interchangeable for sensitive pharmaceutical or biological applications.
Is ventilated or static cooling required for a laboratory?
Static cooling is quieter and better preserves product moisture, which is suitable for samples that must not be dried out. Ventilated cooling ensures superior thermal homogeneity and prevents frost formation, which is advantageous for products sensitive to temperature variations. The choice depends directly on the nature of the stored products and the laboratory's storage requirements.
Are Rewake reconditioned refrigerator-freezer combinations reliable for storing vaccines or sensitive reagents?
Each combination is tested for its actual temperature ranges and the thermal stability of each compartment before shipment. Alarms are verified and measured values are compared to original specifications. Test reports are available on request for laboratories subject to quality audits or regulatory inspections.
What capacity should I choose for a laboratory refrigerator-freezer combination?
The useful volume of each compartment must correspond to the actual volume of products stored simultaneously, taking into account the formats of containers used and the rotation frequency of the products. An overloaded compartment loses thermal homogeneity. Rewake offers models of different capacities and can guide you toward the sizing best suited to your needs.
What maintenance is required for a laboratory refrigerator-freezer combination?
Regular maintenance focuses on five points: disinfection of the compartments according to laboratory protocols, verification of door seals, periodic checking of actual temperatures against setpoints, defrosting if necessary, and checking the compressor and condenser. Rigorous maintenance is essential to maintain the thermal stability and regulatory compliance of the equipment over time.
