As laboratory inventories grow, frozen storage needs to do more than simply maintain temperature. It should provide dependable performance, easy organization, efficient operation, and the flexibility to support busy research and clinical environments. The LABRepCo Futura LABLD-49-FA Double-Door Laboratory Freezer was designed with these priorities in mind, combining laboratory-grade temperature control with a spacious 49 cubic foot cabinet, energy-efficient refrigeration, and modern monitoring features.
With an adjustable operating temperature range of -18°C to -25°C, forced-air circulation, and a double-door upright design, the LABLD-49-FA is well suited for biotechnology companies, pharmaceutical manufacturers, hospitals, universities, environmental laboratories, and industrial quality control facilities requiring dependable frozen storage for valuable laboratory materials. Purchasing a professionally refurbished unit from American Instrument Exchange allows laboratories to expand storage capacity while reducing capital equipment costs.
Laboratories building a complete cold storage strategy often combine high-capacity laboratory freezers with laboratory refrigerators for refrigerated reagents, ultralow freezers for long-term biological preservation, and cryogenic storage systems for specialized liquid nitrogen storage.

LABRepCo Futura LABLD-49-FA Overview
The LABLD-49-FA was engineered for laboratories that require dependable day-to-day frozen storage together with the organizational advantages of a large-capacity cabinet. The double-door configuration allows users to organize inventory efficiently while reducing unnecessary temperature loss by opening only one section of the freezer during routine access.
Forced-air circulation promotes consistent temperatures throughout the storage chamber, while the microprocessor controller continuously monitors cabinet conditions and supports accurate temperature regulation. Battery-backed audible and visual alarms, remote alarm contacts, and a probe access port provide additional confidence for laboratories storing valuable research materials and temperature-sensitive products.
The LABRepCo Futura LABLD-49-FA is commonly used to store:
Biological specimens
Laboratory reagents
Vaccines
Diagnostic materials
Plasma and serum
Enzymes
Antibodies
Pharmaceutical products
Environmental samples
Quality control materials
Laboratory buffers
Research collections
Its large-capacity cabinet makes it particularly well suited for centralized laboratory storage rooms, hospital core laboratories, pharmaceutical production facilities, academic research centers, and industrial laboratories managing large frozen inventories.
Ideal Laboratory Types
The LABLD-49-FA is well suited for:
Biotechnology laboratories
Pharmaceutical manufacturers
Academic research institutions
Hospitals and clinical laboratories
Environmental testing laboratories
Industrial quality control laboratories
Government laboratories
Public health laboratories
Laboratories seeking dependable frozen storage with modern monitoring features and energy-efficient operation will appreciate the balance of capacity, organization, and reliability offered by the Futura platform.
Temperature Uniformity & Sample Protection
Consistent cabinet temperatures are critical for protecting laboratory materials during everyday operation. The LABLD-49-FA utilizes forced-air circulation to maintain temperature uniformity throughout the storage chamber while supporting rapid recovery after routine door openings.
The double-door cabinet design helps reduce unnecessary cold air loss by allowing users to access only one side of the freezer during sample retrieval. Combined with battery-backed alarms and remote monitoring capability, these features help laboratories maintain confidence in the integrity of stored materials.
Typical Stored Materials
The LABLD-49-FA is commonly used to store:
Biological specimens
Plasma and serum
Vaccines
Laboratory reagents
Enzymes
Antibodies
Pharmaceutical compounds
Clinical samples
Environmental testing samples
Quality control standards
Applications requiring storage below -40°C or long-term preservation of DNA libraries, stem cells, and cell lines should instead utilize ultralow freezers.

Energy Efficiency & Operating Costs
The LABLD-49-FA is Energy Star® listed and utilizes natural R290 hydrocarbon refrigerant together with an efficient monoblock compressor system to reduce operating costs while maintaining dependable laboratory performance. Quiet operation—approximately 52 dB—also makes the freezer well suited for laboratories where equipment noise is a consideration. Consolidating multiple smaller freezers into one high-capacity cabinet can further simplify inventory management and reduce overall maintenance requirements.

Refurbishment & Testing Process
Every LABRepCo Futura LABLD-49-FA received by American Instrument Exchange undergoes a comprehensive inspection and performance evaluation before shipment. Our technicians verify refrigeration performance, confirm temperature stability throughout the operating range, inspect the refrigeration system, evaluate door gaskets and cabinet insulation, test alarms and electronic controls, verify controller accuracy, and thoroughly clean the freezer before delivery.
Shipping & Installation Considerations
The LABRepCo Futura LABLD-49-FA ships by freight from American Instrument Exchange. Before delivery, laboratories should verify doorway clearances, electrical service, available floor space, and adequate ventilation around the cabinet. Locking casters simplify positioning during installation while allowing the freezer to be relocated when laboratory layouts change.
