Testing Procedures for Used and Refurbished Ultralow Freezers
Ensure -80°C Stability and Critical Sample Protection

Used and refurbished ultralow freezers from American Instrument Exchange are rigorously tested to ensure reliable long-term storage at temperatures as low as -80°C. Each unit undergoes a detailed inspection, full system evaluation, and extended runtime testing to meet the high standards required by research, clinical, and biorepository environments.

Why Testing Used Ultralow Freezers Is Essential

Before an ultralow freezer is placed back into service, it must be carefully tested for:
• Temperature stability and uniformity at ultralow levels (e.g., -70°C to -86°C)
• Cascade refrigeration system functionality and compressor health
• Seal and insulation effectiveness to prevent thermal loss
• Electrical safety, alarm functionality, and system compliance

Thorough testing helps prevent temperature excursions and equipment failure—crucial for protecting sensitive materials such as biological samples, vaccines, enzymes, and research specimens.
Our structured ULT testing protocol ensures each refurbished unit delivers dependable performance and long-term reliability.

Key Testing Procedures for Refurbished and Used Ultralow Freezers

1. Initial Visual Inspection

• Inspect external cabinet, hinges, and door gaskets for wear, corrosion, or damage
• Check power cords, plugs, and control interfaces for signs of wear or tampering
• Verify that internal racks, shelving, and chamber components are intact and operational

2. Functional Startup and Control Testing

• Power on the unit and confirm successful initialization of digital displays and alarm systems
• Test control panels, keypad responsiveness, and user-setpoint functionality
• Verify that door seals close tightly and form a secure barrier

3. Temperature and -80°C Stability Testing

• Test and evaluate internal temperature sensors thermometers/probes
• Monitor temperature performance at multiple chamber points over extended runtimes
• Confirm uniformity and stability at key setpoints, including -70°C, -80°C, and -86°C

4. Refrigeration System and Cascade Compressor Evaluation

• Test dual-stage (cascade) compressor function, startup times, and cycling behavior
• Evaluate evaporator coils, heat exchangers, and vacuum insulation panels for performance and integrity
• Check for refrigerant leaks, low-pressure faults, and abnormal compressor noise

5. Alarm and Safety System Verification

• Test high/low temperature alarms, power failure alerts, and battery backup systems (if equipped)
• Verify lockout controls, alarm delay settings, and door-open indicators

6. Final Quality Assurance and Documentation

• Run a continuous multi-day test cycle at -80°C to confirm sustained performance
• Document temperature logs, controller accuracy, and compressor behavior
• Complete a detailed service report
