Overview
The Jewett CT1 was developed for facilities requiring dependable blood storage in areas where floor space is limited. Although compact, it utilizes the same refrigeration technology and monitoring systems found in larger Jewett blood bank refrigerators, providing excellent temperature uniformity and rapid recovery following door openings.
The removable countertop allows the unit to be installed either as a freestanding counter-height refrigerator or beneath a laboratory counter. Positive forced-air circulation maintains consistent temperatures throughout the cabinet, while the integrated monitoring system continuously records storage conditions for quality assurance and regulatory documentation.
Common Applications
The Jewett CT1 is commonly used for storing whole blood, packed red blood cells, blood components, transfusion products, blood typing reagents, quality-control materials, and other temperature-sensitive clinical products requiring storage between 2°C and 4°C. Its compact size makes it particularly well suited for hospital laboratories, blood banks, emergency departments, surgical suites, outpatient transfusion centers, and satellite laboratory locations where blood products must remain readily available near the point of care.

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.
