Overview
The Thermo Scientific Revco RFMS2305A is a specialized laboratory refrigerator developed for facilities that need to maintain flammable chemicals and other compatible materials at controlled refrigerated temperatures.
Its 23 cu. ft. chamber provides substantial storage capacity while retaining the convenience of a single-door upright refrigerator. Four adjustable shelves allow laboratory personnel to organize bottles, chemical containers, reagents, and other approved materials according to their storage requirements.
The RFMS2305A differs from an ordinary laboratory refrigerator because its refrigerated compartment is designed without electrical components that could produce sparks or other potential ignition sources. This design is important when storing flammable liquids that may release combustible vapors.
The refrigerator uses a microprocessor-based temperature controller and digital display to support monitoring and adjustment of storage conditions. Its operating range of +1°C to +8°C makes it appropriate for compatible materials requiring conventional laboratory refrigeration.
An integrated alarm system provides notification of abnormal temperature conditions, door openings, power failures, and other operating concerns. Battery-backed alarm monitoring adds protection during certain electrical interruptions.
For laboratories replacing older chemical-storage refrigerators or expanding refrigerated solvent-storage capacity, a refurbished RFMS2305A offers a practical alternative to purchasing new specialized cold-storage equipment.
Flammable Material Storage & Laboratory Safety
The primary distinction between the Thermo Scientific RFMS2305A and a standard laboratory refrigerator is its flammable-material storage design.
Conventional refrigerators may contain internal electrical switches, thermostats, lights, or other components capable of producing sparks. These components can create ignition hazards when flammable vapors accumulate inside a refrigerated compartment.
The RFMS2305A is designed to eliminate such potential ignition sources from its interior storage space.
This makes it suitable for refrigerated storage of compatible flammable liquids, solvents, and chemical materials when used in accordance with applicable safety requirements.
However, a flammable-material storage refrigerator is not the same as an explosion-proof refrigerator.
The RFMS2305A is intended for appropriate laboratory environments where flammable materials must be stored inside the refrigerator. It is not designed for installation in classified hazardous locations where flammable vapors may be present in the surrounding room and explosion-proof electrical construction is required.
Laboratories should consult their environmental health and safety personnel, applicable fire codes, chemical safety data sheets, and facility requirements before selecting refrigerated storage equipment for flammable chemicals.
Thermo Scientific RFMS2305A flammable material storage refrigerator Common Applications
The Thermo Scientific RFMS2305A is designed for refrigerated storage of compatible flammable laboratory materials, including certain organic solvents, chemical reagents, analytical standards, research compounds, and other temperature-sensitive chemicals.
Typical applications include pharmaceutical research, analytical chemistry, chemical synthesis, biotechnology research, environmental testing, industrial quality control, and laboratories handling volatile organic compounds.
The refrigerator may also be appropriate for certain flammable solutions used in chromatography, sample preparation, chemical analysis, and research workflows when the materials require refrigerated storage within the specified temperature range.
Storage suitability should always be determined from the chemical manufacturer's safety data sheet and applicable laboratory safety procedures. Not all flammable materials require refrigeration, and not every chemical is compatible with the same storage environment.
Ideal Laboratory Types
The RFMS2305A is well suited for pharmaceutical laboratories, chemical research facilities, analytical testing laboratories, biotechnology companies, university chemistry departments, industrial research facilities, environmental testing laboratories, and quality-control departments.
Facilities that routinely handle flammable solvents or temperature-sensitive chemical reagents may benefit from maintaining a dedicated refrigerator specifically designed for flammable-material storage.
The 23 cu. ft. capacity makes the RFMS2305A particularly useful for laboratories requiring more storage than compact benchtop or undercounter flammable-material refrigerators can provide.
Its combination of specialized interior construction, temperature monitoring, security features, and alarm protection supports laboratories seeking to improve organization and oversight of refrigerated chemical inventory.
Temperature Recovery & Uniformity
The Thermo Scientific RFMS2305A operates over a temperature range of +1°C to +8°C, with a factory preset temperature of +5°C.
Its microprocessor-based control system monitors refrigeration performance and provides digital temperature information for laboratory personnel.
High- and low-temperature alarms help identify conditions outside the selected operating limits, while the door-ajar alarm alerts users when the refrigerator door remains open.
Temperature recovery following routine access depends on ambient laboratory conditions, stored material quantity, container size, shelf arrangement, and the duration of door openings.
Organizing frequently accessed chemicals for efficient retrieval can help minimize unnecessary temperature disturbances.
The four adjustable shelves also allow users to accommodate different container heights while maintaining suitable spacing for normal refrigeration performance.
For applications requiring documented temperature performance, laboratories should consider independent temperature monitoring and appropriate recordkeeping procedures.
Chemical Storage Recommendations
The RFMS2305A should be used only for materials whose storage requirements are compatible with its +1°C to +8°C operating range and flammable-material storage design.
Chemicals should remain in properly labeled, compatible, securely closed containers. Secondary containment may be appropriate depending on the chemical, container type, and laboratory safety procedures.
Materials should be organized by chemical compatibility rather than simply by available shelf space. Incompatible chemicals should not be stored together merely because they share the same temperature requirements.
The refrigerator's adjustable shelving can accommodate different bottle and container sizes, but users should avoid overcrowding or arranging materials in ways that interfere with normal cooling performance.
Because the RFMS2305A uses manual defrost, laboratories should establish appropriate procedures for managing frost accumulation and temporarily relocating materials when defrosting is required.
Laboratories should also maintain an inventory of stored chemicals and follow applicable requirements for flammable-liquid quantities, container compatibility, labeling, and emergency response.
