VWR Explosion-Proof Combination Refrigerator/Freezer

The VWR Explosion-Proof Combination Refrigerator/Freezer is a laboratory-grade cold storage system engineered for the safe refrigerated and frozen storage of flammable chemicals in hazardous locations where ignitable vapors may be present. Featuring separate refrigerator and freezer compartments with a combined storage capacity of 10.1 cubic feet (286 L), this explosion-proof unit is designed for pharmaceutical laboratories, chemical manufacturing facilities, research institutions, industrial laboratories, and other environments requiring equipment suitable for Class I hazardous locations.

Unlike flammable-material storage refrigerators, which are intended for non-hazardous laboratory spaces, the VWR Explosion-Proof Combination Refrigerator/Freezer is engineered with explosion-proof electrical components and a hermetically sealed refrigeration system to minimize ignition hazards in hazardous work environments. Spark-resistant interior construction, corrosion-resistant materials, and heavy-duty insulation provide dependable temperature performance while supporting safe laboratory operation.

Many laboratories pair explosion-proof refrigerators with chemical fume hoods, biosafety cabinets, laboratory freezers, and centrifuges to create complete laboratory workstations for handling hazardous chemicals.

Overview

The VWR Explosion-Proof Combination Refrigerator/Freezer is designed for laboratories where flammable vapors may routinely be present and standard laboratory refrigerators cannot be safely used. Explosion-proof electrical components are enclosed to prevent internal electrical arcs or sparks from igniting surrounding hazardous atmospheres, making the unit appropriate for laboratories that work with volatile solvents and combustible chemicals.

Separate refrigerator and freezer compartments allow laboratories to safely store materials requiring different temperature ranges without purchasing multiple explosion-proof cabinets. The corrosion-resistant interior and hermetically sealed compressor are designed for long-term laboratory service in demanding chemical environments.

Common Applications

The VWR Explosion-Proof Combination Refrigerator/Freezer is commonly used for storing volatile solvents, chromatography reagents, petroleum products, alcohols, laboratory standards, chemical reference materials, pharmaceutical ingredients, flammable reagents, and other hazardous materials requiring refrigerated or frozen storage. It is frequently installed in chemical laboratories, pharmaceutical manufacturing facilities, petrochemical laboratories, industrial quality-control departments, and research facilities where hazardous atmospheres may be present.

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.
