The Fisher Isotemp Flammable Materials Storage Refrigerator, Catalog Number 13-986-152, is a laboratory-grade refrigerator specifically designed for the safe refrigerated storage of volatile and flammable chemicals where a spark-free interior cabinet is required. Offering 21 cubic feet (595 L) of storage capacity and an operating temperature range of 1°C to 12°C, this upright refrigerator provides dependable cold storage for solvents, reagents, standards, and other flammable laboratory materials while helping laboratories comply with accepted laboratory safety practices.
Unlike a conventional laboratory refrigerator, the 13-986-152 is engineered so that no ignition sources are located inside the refrigerated compartment. Electrical components that could generate sparks are isolated from the storage chamber, reducing the risk associated with storing flammable materials. The refrigerator features manual defrost operation, fixed shelving, magnetic door gaskets, and laboratory-grade construction suitable for research, pharmaceutical, industrial, and quality-control laboratories. Designed to meet NFPA 45, NFPA 99, and OSHA 1910.307 requirements for flammable materials storage refrigerators, this model is intended for use in non-hazardous laboratory environments where a spark-free cabinet interior is required. It is not an explosion-proof refrigerator for hazardous (classified) locations.

Refurbishment & Testing Process
Every Fisher Isotemp 13-986-152 received by American Instrument Exchange undergoes a comprehensive inspection before shipment. Our technicians verify cabinet temperature using calibrated monitoring equipment, inspect the refrigeration system, temperature controller, shelving, door gasket, and overall cabinet condition. Each refrigerator is thoroughly cleaned, temperature tested, and verified for dependable laboratory operation before shipment.
The Fisher Isotemp 13-986-152 ships by freight from American Instrument Exchange. Before installation, verify adequate electrical service and proper ventilation clearance. This refrigerator is intended for installation in non-classified laboratory spaces and should not be substituted for an explosion-proof refrigerator where hazardous location requirements apply. Allow the cabinet to stabilize at operating temperature before loading flammable materials.
Frequently Asked Questions
What is the difference between a flammable materials storage refrigerator and an explosion-proof refrigerator?
A flammable materials storage refrigerator provides a spark-free interior for storing volatile chemicals in standard laboratory environments. An explosion-proof refrigerator is designed for hazardous (classified) locations where flammable vapors may be present outside the cabinet and includes explosion-proof electrical components throughout the unit.
What temperature range does this refrigerator maintain?
The Fisher Isotemp 13-986-152 is designed to maintain temperatures between 1°C and 12°C.
What types of materials can be stored inside?
This refrigerator is intended for refrigerated storage of volatile solvents, flammable chemicals, analytical standards, reagents, and other laboratory materials requiring a spark-free storage environment.
How is the refrigerator tested before shipment?
Every refurbished Fisher Isotemp 13-986-152 is inspected and temperature tested by American Instrument Exchange technicians. Refrigeration performance, temperature control, cabinet condition, and overall operation are verified before shipment.

Testing Procedures for Used and Refurbished Laboratory Refrigerators Ensure Temperature Stability and Cold Storage Accuracy
Used and refurbished laboratory refrigerators from American Instrument Exchange are thoroughly tested to ensure reliable cold storage performance, temperature accuracy, and compliance with laboratory safety and storage standards. Each unit undergoes a detailed inspection and functional verification to meet the requirements of clinical, pharmaceutical, research, and industrial labs.
Why Testing Used Laboratory Refrigerators Is Essential
Before a laboratory refrigerator is reintroduced into any laboratory setting, it must be carefully tested for:
• Temperature uniformity and stability
• Cooling system integrity and compressor function
• Door seal performance and insulation effectiveness
• Electrical safety and compliance with lab standards
Thorough testing minimizes the risk of temperature excursions, product loss, and system failures—especially critical for storing reagents, vaccines, biological samples, pharmaceuticals, and temperature-sensitive materials.
Our structured testing protocol ensures refurbished lab refrigerators deliver consistent, dependable performance across all makes and models.
Key Testing Procedures for Refurbished and Used Laboratory Refrigerators
1. Initial Visual Inspection
• Check exterior surfaces, hinges, and door gaskets for wear, corrosion, or damage
• Inspect power cords, plugs, and control panels for fraying or visible defects
• Verify that shelves, racks, and internal compartments are present and functional
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
