Overview
Chromatography refrigerators differ from conventional laboratory refrigerators because they are designed not only to store refrigerated materials, but also to accommodate equipment and experimental workflows inside the temperature-controlled chamber. The Fisherbrand Isotemp GTFBG45CPLA combines a spacious 45 cu. ft. interior with access ports and internal electrical power, making it particularly useful for laboratories performing chromatography, protein purification, and other temperature-sensitive procedures.
The large interior provides room for chromatography columns, fraction collectors, collection vessels, tubing, buffers, reagents, and compatible powered equipment. The cabinet can also be configured to provide conventional refrigerated storage when it is not being used for active chromatography work.
One of the distinguishing features of the GTFBG45CPLA is its two sliding double-pane glass doors. The sliding design allows users to access one section of the refrigerator without opening the entire front of the cabinet, while the glass construction makes it possible to inspect equipment, samples, and collection vessels without opening the doors at all.
Access ports allow tubing, electrical cables, monitoring probes, and other connections to pass between equipment inside and outside the refrigerated chamber. An internal electrical outlet provides power for compatible equipment operating within the refrigerator, helping laboratories avoid improvised cable routing through the door opening.
The combination of substantial interior capacity and chromatography-specific features makes the GTFBG45CPLA a flexible option for laboratories that need more working room than a single-door chromatography refrigerator can provide.
Common Applications
The Fisherbrand GTFBG45CPLA is well suited for protein purification, column chromatography, FPLC workflows, refrigerated fraction collection, buffer preparation and storage, sample preparation, and other temperature-sensitive analytical procedures.
Its large interior can accommodate chromatography equipment and associated supplies while maintaining refrigerated conditions throughout a procedure. This can be particularly valuable for proteins, enzymes, biological samples, and other materials whose stability may depend on maintaining lower temperatures during purification or processing.
When not being used for active chromatography work, the refrigerator can provide high-capacity storage for reagents, proteins, enzymes, media, buffers, biological samples, standards, controls, and other materials requiring refrigerated storage within its specified temperature range.
Ideal Laboratory Types
The Fisherbrand Isotemp GTFBG45CPLA is an excellent option for biotechnology laboratories, pharmaceutical research facilities, protein purification laboratories, academic research groups, biochemistry laboratories, analytical laboratories, life science facilities, and industrial R&D laboratories.
The 45 cu. ft. capacity makes this model particularly attractive for laboratories with higher sample volumes, larger chromatography systems, or multiple researchers sharing a refrigerated chromatography workspace.
It can also be a practical choice for growing laboratories that want sufficient capacity to support both current chromatography workflows and additional refrigerated storage requirements.
Performance & Temperature Uniformity
The Fisherbrand GTFBG45CPLA operates across a 2°C to 10°C temperature range, covering the refrigerated conditions commonly required for chromatography procedures, reagents, buffers, proteins, and other laboratory materials.
The glass doors allow laboratory personnel to visually monitor equipment and stored materials without opening the refrigerator, helping reduce unnecessary introduction of warmer ambient air into the cabinet. When access is required, the two-door sliding configuration allows users to open only the portion of the cabinet necessary for the task.
The refrigerator incorporates audible and visual alarm functions for temperature excursions, open-door conditions, and power failure. Battery backup helps maintain alarm functionality during power interruptions, while remote alarm contacts provide the ability to connect the refrigerator to compatible external monitoring or facility alarm systems.
For laboratories storing particularly valuable or sensitive materials, independent temperature monitoring or data logging may provide an additional layer of protection and documentation.
Sample Storage Recommendations
For routine refrigerated storage, samples, reagents, and containers should be arranged to permit adequate airflow throughout the chamber. Avoid tightly packing materials against interior air passages or positioning large containers in ways that could interfere with air circulation.
When configuring the GTFBG45CPLA for chromatography applications, sufficient clearance should be maintained around pumps, columns, fraction collectors, collection vessels, and other equipment. This helps preserve airflow while also providing researchers with adequate access to make adjustments or inspect the system during operation.
The refrigerator's access ports are particularly useful when external connections are required. Tubing, monitoring probes, electrical cables, or other compatible connections can be routed through these ports rather than through the door opening.
For high-value samples or applications requiring documented storage conditions, laboratories should consider using an independent temperature monitoring system or data logger in addition to the refrigerator's onboard controls and alarms.

Energy Efficiency & Operating Costs
The Fisherbrand Isotemp GTFBG45CPLA incorporates several features intended to support efficient laboratory operation, including natural hydrocarbon refrigerant, adaptive defrost, LED interior lighting, and low-heat-output operation.
The double-pane glass doors also allow users to locate materials and visually monitor chromatography equipment before opening the cabinet. Reducing unnecessary door openings can limit the amount of warm laboratory air entering the chamber and reduce the cooling system's recovery workload.
The sliding double-door configuration provides an additional advantage on a cabinet of this size because only a portion of the refrigerator needs to be opened for many routine tasks.
Actual energy consumption will vary according to laboratory temperature, refrigerator setpoint, door-opening frequency, sample loading, and the amount and heat output of equipment operating inside the chamber.
