VWR Explosion-Proof Laboratory Refrigerator

The VWR Explosion-Proof Laboratory Refrigerator is a laboratory-grade refrigerator engineered for the safe refrigerated storage of flammable and volatile chemicals in hazardous locations where ignitable vapors may be present. Offering 14 cubic feet (396.4 L) of refrigerated storage capacity and an operating temperature range of 0°C to 10°C, this explosion-proof refrigerator is designed for chemical laboratories, pharmaceutical manufacturers, petrochemical facilities, research institutions, and industrial laboratories requiring refrigeration equipment suitable for hazardous environments.

Unlike flammable material storage refrigerators, which are intended for use in non-hazardous laboratory spaces, the VWR Explosion-Proof Laboratory Refrigerator incorporates explosion-proof electrical construction and a hermetically sealed refrigeration system to reduce ignition hazards where combustible vapors may be present. Non-sparking magnetic door gaskets, heavy-duty cabinet construction, and hardwired installation further enhance laboratory safety while providing dependable refrigerated storage for hazardous materials. The refrigerator is designed for use in accordance with NFPA 45 and NFPA 70 guidelines for hazardous laboratory environments.

Many laboratories pair explosion-proof refrigeration with chemical fume hoods, biosafety cabinets, laboratory freezers, and centrifuges to create a complete hazardous-material handling workflow.

Routine condenser cleaning, proper ventilation, and periodic inspection of door gaskets will help maintain dependable refrigeration performance and extend equipment life.

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

Refurbishment & Testing Process

Every VWR Explosion-Proof Laboratory Refrigerator received by American Instrument Exchange undergoes a comprehensive inspection before shipment. Our technicians verify temperature accuracy using calibrated temperature monitoring equipment, inspect the refrigeration system, shelving, door gaskets, cabinet integrity, and overall operation. Each refrigerator is thoroughly cleaned, temperature tested, and verified for dependable laboratory performance before shipment.

Laboratories building complete hazardous-material storage systems frequently purchase chemical fume hoods, laboratory freezers, biosafety cabinets, and additional laboratory refrigerators from American Instrument Exchange.

Shipping & Installation Considerations

The VWR Explosion-Proof Laboratory Refrigerator ships by freight from American Instrument Exchange. Before installation, verify doorway clearances, available electrical service, and compliance with local electrical and fire codes. Because this is an explosion-proof refrigerator, it must be hardwired by a qualified electrician into an approved conduit box. Allow the refrigerator to stabilize at operating temperature before loading valuable laboratory materials.

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
• 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.
