VWR Chromatography Refrigerator – Catalog No. 89209-824 (Model MH45PA-GAEE-VW)

The VWR Chromatography Refrigerator, Catalog Number 89209-824 (Model MH45PA-GAEE-VW) is a laboratory-grade chromatography refrigerator engineered for protein purification, FPLC systems, HPLC sample preparation, and other temperature-sensitive analytical workflows. Offering approximately 45 cubic feet of refrigerated storage with a temperature range of 2°C to 8°C, the MH45PA-GAEE-VW provides the space and specialized features needed to operate chromatography equipment while maintaining stable refrigerated conditions for sensitive biological samples and reagents.

Unlike a standard laboratory refrigerator, this chromatography model is specifically designed to house complete purification systems. It features insulated glass doors for product visibility, forced-air refrigeration for excellent temperature uniformity, cable access ports, an internal duplex electrical outlet, a chromatography mast, digital temperature control, and laboratory-grade alarm monitoring. These features allow chromatography instruments to operate continuously inside the refrigerated chamber while maintaining precise temperature control.

Many laboratories pair chromatography refrigerators with centrifuges, ultra-low freezers, biosafety cabinets, and laboratory freezers to create complete protein purification and cold-storage workflows.

Overview

The VWR MH45PA-GAEE-VW was designed specifically for laboratories performing chromatography and protein purification where maintaining refrigerated operating conditions is essential for sample integrity. Rather than simply storing reagents, the refrigerator accommodates complete purification systems—including pumps, chromatography columns, fraction collectors, and tubing—inside the temperature-controlled cabinet.

Integrated cable access ports allow electrical cords and fluid tubing to pass through the cabinet while minimizing temperature loss. The internal electrical outlet simplifies instrument installation, while insulated glass doors improve inventory visibility and reduce unnecessary door openings during extended purification runs.

Common Applications

The MH45PA-GAEE-VW is commonly used for ÄKTA chromatography systems, FPLC purification, Bio-Rad NGC systems, affinity chromatography, ion exchange chromatography, size exclusion chromatography, antibody purification, recombinant protein purification, enzyme purification, fraction collection, HPLC sample preparation, and refrigerated storage of chromatography buffers, standards, media, and biological samples.

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.
