Thermo Scientific Flammable Material Combination Refrigerator/Freezer – Model GTT8H07CF8A

The Thermo Scientific Flammable Material Combination Refrigerator/Freezer, Model GTT8H07CF8A, is a laboratory-grade combination refrigerator and freezer specifically engineered for the safe storage of flammable and volatile chemicals. Featuring separate refrigerated and frozen storage compartments within a single cabinet, the GTT8H07CF8A provides laboratories with the flexibility to safely store solvents, reagents, standards, and temperature-sensitive flammable materials while meeting laboratory safety requirements for spark-free interior storage.

Unlike standard laboratory refrigerators, the GTT8H07CF8A is designed with a spark-free interior, eliminating electrical components within the storage compartments that could ignite flammable vapors. Manual defrost operation, external temperature controls, magnetic door gaskets, and CFC- and HCFC-free insulation contribute to dependable temperature performance while complying with laboratory safety standards for flammable material storage. Units in this series are designed to meet NFPA 45, NFPA 70, and applicable OSHA requirements for the storage of flammable chemicals.

Many laboratories pair flammable material storage refrigerators with ultra-low freezers for biological preservation, biosafety cabinets for sterile processing, chemical fume hoods for solvent handling, and laboratory refrigerators to create a complete laboratory cold-storage solution.

Overview

The Thermo Scientific GTT8H07CF8A provides laboratories with a practical solution for safely storing both refrigerated and frozen flammable materials within a single cabinet. Rather than purchasing separate flammable-storage refrigerator and freezer units, laboratories can consolidate both storage requirements while conserving valuable floor space.

The cabinet's spark-free interior is specifically engineered to reduce the possibility of ignition from internal electrical components. External thermostat controls eliminate the need to open the cabinet during routine temperature adjustments, while manual defrost operation helps maintain stable storage conditions for sensitive laboratory materials.

Common Applications

The Thermo Scientific GTT8H07CF8A is commonly used for the safe storage of ethanol, methanol, acetone, isopropanol, volatile organic compounds (VOCs), chromatography solvents, pharmaceutical ingredients, laboratory standards, chemical reagents, reference materials, and other flammable or combustible laboratory chemicals requiring refrigerated or frozen storage. It is frequently found in pharmaceutical laboratories, analytical chemistry laboratories, environmental testing facilities, research institutions, and industrial quality-control laboratories.

Ideal Laboratory Types

Pharmaceutical laboratories
Biotechnology laboratories
Chemical laboratories
Environmental testing laboratories
Academic research laboratories
Hospital research facilities
Industrial quality assurance laboratories

2. Functional Testing
• Power on the refrigerator and verify that display screens, alarms, and controls function properly
• Test door latches and sealing mechanisms to ensure secure closure and insulation
• Run preliminary temperature cycles to observe startup behavior and cooling response

3. Temperature and Stability Testing
• Test internal temperature sensors and controllers using thermometers/probes
• Monitor temperature at multiple points within the chamber over an extended period
• Verify accuracy across user-defined setpoints (e.g., +4°C, +2°C to +8°C range)

4. Cooling System and Compressor Evaluation
• Test compressor startup, cycling, and operating noise levels
• Inspect condenser coils and fans for proper function and cleanliness
• Check refrigerant pressure (if applicable) and confirm there are no leaks or system inefficiencies

5. Electrical Safety and Compliance Checks
• Ensure all internal and external electrical components are properly grounded
• Perform insulation resistance and leakage current tests
6. Final Quality Assurance Checklist
• Run full operational tests over a 24-hour period
• Document temperature logs, control responsiveness, and system performance
• Complete a detailed service report

All refurbished laboratory refrigerators from American Instrument Exchange are backed by our rigorous testing standards and quality commitment. From vaccine storage to reagent preservation, you can count on consistent cold storage performance from day one.
