Thermo GPF Series Benchtop Laboratory Freezer

In many laboratories, efficiency comes down to keeping frequently used materials within arm's reach. The Thermo GPF Series Benchtop Laboratory Freezer was designed specifically for laboratories that need dependable frozen storage without sacrificing valuable floor space. With a footprint comparable to a microwave oven, this compact freezer sits directly on a laboratory bench, allowing researchers to access reagents, standards, and temperature-sensitive materials without leaving the workstation.

Offering 1.13 cubic feet (32 liters) of storage capacity and operating at -20°C, the GPF Series freezer is an excellent solution for biotechnology laboratories, pharmaceutical research, hospitals, clinical laboratories, and quality control facilities. Its compact size, digital controls, and laboratory-specific features make it well suited for storing frequently accessed frozen materials while improving day-to-day laboratory workflow.

Many laboratories pair a benchtop freezer like the GPF with laboratory refrigerators for refrigerated reagents, larger laboratory freezers for bulk frozen storage, ultralow freezers for long-term biological preservation, and biosafety cabinets to create efficient laboratory workstations.

Thermo GPF Series Overview

The Thermo GPF Series was developed for laboratories that need immediate access to frozen materials throughout the day. Rather than requiring researchers to walk to a central freezer, the compact cabinet can be positioned directly on a countertop or laboratory bench, reducing interruptions during sample preparation and analytical workflows.

Despite its small size, the freezer incorporates features typically found on larger laboratory systems, including a digital controller, remote alarm contacts, an access port for monitoring probes, audible and visual temperature alarms, and a lockable door. These features make it suitable for both research and clinical environments where temperature monitoring and sample security are important.

Common Applications

The Thermo GPF Series is commonly used for storing:

PCR reagents
Restriction enzymes
Antibodies
Diagnostic reagents
Vaccines
Pharmaceutical products
Laboratory standards
Protein samples
Quality control materials
Environmental testing samples
Frequently used research reagents

Its countertop design makes it ideal for materials that are accessed multiple times throughout the day.

Ideal Laboratory Types

The GPF Series is well suited for:

Biotechnology laboratories
Pharmaceutical laboratories
Clinical laboratories
Hospital laboratories
Academic research laboratories
Environmental testing laboratories
Quality control laboratories
Teaching laboratories

The compact footprint is particularly valuable in laboratories where bench space is available but floor space is limited.

Workflow & Point-of-Use Storage

The greatest advantage of the GPF Series is convenience. By positioning frozen materials directly within the laboratory workspace, researchers spend less time walking between workstations and central cold storage. This can improve efficiency during repetitive procedures such as PCR setup, molecular biology workflows, and routine quality control testing.

The ergonomic handle, top-mounted controls, reversible door, and external temperature display were all designed to simplify daily operation in busy laboratory environments.

Typical Stored Materials

The Thermo GPF Series is commonly used to store PCR reagents, restriction enzymes, antibodies, vaccines, protein extracts, laboratory standards, pharmaceutical products, quality control materials, environmental samples, and other research reagents requiring -20°C storage.

Applications requiring storage below -80°C, such as stem cells, cell lines, tissue archives, or long-term DNA preservation, are better suited for dedicated ultralow freezers or cryogenic storage systems.

Specifications compiled from Thermo Scientific manufacturer literature and American Instrument Exchange product information.

Refurbishment & Testing Process

Every Thermo GPF Series freezer received by American Instrument Exchange undergoes a comprehensive inspection and performance evaluation before shipment. Our technicians verify temperature accuracy using calibrated probes, inspect the refrigeration system, test alarms and digital controls, confirm remote alarm functionality, inspect the door seal and shelving, replace worn components as necessary, and thoroughly clean the freezer before delivery.

Laboratories purchasing compact laboratory freezers frequently pair them with laboratory refrigerators, laboratory freezers, ultralow freezers, biosafety cabinets, and centrifuges from American Instrument Exchange.

Shipping & Installation Considerations

The Thermo GPF Series ships by freight or parcel service, depending on the order. Before installation, laboratories should verify available bench space, electrical service, and ventilation clearances around the cabinet. Allowing adequate airflow around the refrigeration system will help maintain consistent cooling performance and maximize equipment life.

Testing Procedures for Used and Refurbished Laboratory Freezers

Cold Storage Reliability from American Instrument Exchange

At American Instrument Exchange, every used and refurbished laboratory freezer we offer undergoes a comprehensive multi-point testing protocol to ensure optimal performance, temperature stability, and long-term reliability. Our rigorous testing procedures are designed to meet the demanding standards of biomedical, pharmaceutical, research, and clinical environments—so you can trust your freezer to protect your valuable samples and materials.

Why Testing Refurbished Laboratory Freezers Is Critical

Before any laboratory freezer is placed back into service, it must be carefully tested for:

Consistent temperature control and uniformity across internal zones
Compressor functionality and refrigeration system performance
Seal integrity and insulation efficiency to prevent temperature loss
Electrical safety and alarm system operation

Thorough testing minimizes the risk of temperature excursions, equipment failure, and product loss—especially for temperature-sensitive items like reagents, biological samples, and vaccines.

Our structured testing protocol ensures that all used and refurbished laboratory freezers meet or exceed manufacturer specifications and industry expectations.
