Refurbishment and Testing Process

At American Instrument Exchange, each refurbished refrigerated incubator is inspected and evaluated by our technicians prior to shipment. Testing procedures may include temperature verification throughout the operating range, refrigeration system evaluation, controller functionality testing, display verification, airflow assessment, door gasket inspection, shelving evaluation, and general operational testing. Components showing excessive wear are addressed as needed to help ensure reliable operation. Final cleaning and inspection are completed before packaging and shipment.

Shipping and Installation Considerations

The Thermo Scientific PR505755R is a large-capacity floor model incubator that requires adequate ventilation clearance and a properly grounded 115V electrical supply. Buyers should verify doorway dimensions, hallway clearance, elevator access, and final installation location before delivery. Because of its size and weight, the incubator is typically shipped by freight carrier and should be allowed to stabilize after transport before being placed into service.

Related Laboratory Equipment

Laboratories purchasing refrigerated incubators often also require biosafety cabinets, centrifuges, laboratory refrigerators, ultra-low freezers, and analytical balances. American Instrument Exchange offers a wide selection of refurbished laboratory equipment to support environmental testing, microbiology, pharmaceutical research, and quality control applications.

Testing Procedures for Used and Refurbished Laboratory Incubators
Ensure Quality and Stability Before Use

Used and refurbished laboratory incubators from American Instrument Exchange are thoroughly tested to ensure optimal performance and temperature stability with laboratory safety standards. Each unit undergoes a detailed inspection and functionality assessment to meet the needs of research, clinical, and industrial labs.

Why Testing Used Laboratory Incubators Is Essential

Before a laboratory incubator is reintroduced into any work environment, it must be tested for:
• Temperature uniformity and accuracy
• Airflow and humidity control (if applicable)
• Door seal integrity and insulation effectiveness
• Electrical and safety system compliance

Comprehensive testing reduces the risk of culture loss, contamination, and equipment failure—especially critical in applications involving cell culture, microbiology, pharmaceutical research, and diagnostics.

Our multi-point testing protocol for used and refurbished incubators ensures reliability, safety, and performance across all models and brands.

Key Testing Procedures for Refurbished and Used Laboratory Incubators

1. Initial Visual Inspection
• Check for cosmetic damage, corrosion, and wear to exterior surfaces, door hinges, and gasket seals
• Inspect power cord, wiring, and display panel for any defects or signs of tampering
• Confirm that shelves, chamber components, and internal fixtures are present and undamaged

2. Functional Testing
• Power on the incubator and verify all display indicators and alarms function correctly
• Test door latch and seal mechanisms for proper closure and insulation
• Run basic temperature cycles to ensure the unit maintains stability over time

3. Temperature Accuracy and Uniformity Tests
• Test internal sensors and controllers using temperature probes
• Measure temperature consistency at multiple chamber locations over several hours
• Confirm that programmable temperature settings respond accurately

4. Airflow and Humidity Control (if applicable)
• Test internal fan operation and airflow distribution
• For humidified incubators, inspect and test humidity reservoirs, sensors, and control systems
• Check for condensation buildup and confirm environmental stability

5. Electrical Safety and Compliance Checks
• Ensure all electrical components are properly grounded
• Perform insulation resistance and leakage current tests
• Verify compliance with current electrical safety standards for laboratory equipment

6. Final Quality Assurance Checklist
• Perform full cycle testing at various temperature setpoints
• Document performance benchmarks and results

All refurbished incubators from American Instrument Exchange are backed by our commitment to quality and precision. With our strict testing procedures, you can rely on your incubator to deliver dependable results from day one.
