Fisher Laboratory Freezer 13-986-247

Many laboratories need dependable frozen storage for reagents, standards, biological samples, and research materials without the expense or complexity of an ultra-low freezer. The Fisher Laboratory Freezer 13-986-247 provides reliable -12°C to -20°C storage in a spacious upright cabinet, making it an excellent solution for general laboratory applications where consistent subzero temperatures are essential. Its large interior, simple manual defrost design, and durable construction make it well suited for laboratories that value reliability and straightforward operation.

The Fisher 13-986-247 is an excellent choice for biotechnology companies, pharmaceutical manufacturers, hospitals, universities, environmental laboratories, quality control facilities, and industrial research laboratories storing enzymes, reagents, biological specimens, standards, and laboratory chemicals requiring frozen storage. Many laboratories also choose this style of freezer because manual-defrost cabinets eliminate the periodic warming cycles associated with automatic defrost systems, helping maintain more consistent sample temperatures.

Many laboratories pair a general-purpose laboratory freezer like the 13-986-247 with laboratory refrigerators for refrigerated materials, ultra-low freezers for long-term preservation, biosafety cabinets for sterile sample preparation, and centrifuges to create a complete laboratory cold storage workflow.

Fisher Laboratory Freezer 13-986-247 Overview

The Fisher 13-986-247 is designed for laboratories that require dependable frozen storage with minimal complexity. Unlike ultra-low freezers that operate at -80°C, this freezer is intended for everyday laboratory materials that require conventional frozen storage while offering lower operating costs and easier maintenance.

Its manual-defrost refrigeration system is particularly attractive for laboratories storing temperature-sensitive materials because it avoids the periodic warming cycles common in frost-free commercial freezers. The large upright cabinet provides organized storage using fixed shelves, allowing researchers to separate samples by project, department, or application while maintaining easy access throughout the workday.

Common Applications

The Fisher 13-986-247 is commonly used for storing:

Laboratory reagents
Biological samples
Enzymes
Protein samples
Research chemicals
Cell culture reagents
Diagnostic kits
Calibration standards
Environmental samples
Quality control materials

Ideal Laboratory Types

This freezer is well suited for:

Biotechnology companies
Pharmaceutical manufacturers
Academic research laboratories
Clinical laboratories
Hospitals
Environmental laboratories
Industrial research facilities
Quality control laboratories

Laboratories requiring dependable frozen storage without the expense of an ultra-low freezer will appreciate its combination of capacity, reliability, and simple operation.

Why Choose a Manual-Defrost Laboratory Freezer?

Many research laboratories intentionally select manual-defrost freezers because they maintain more stable cabinet temperatures than automatic-defrost systems. Automatic defrost cycles periodically warm the evaporator to remove frost, while manual-defrost units avoid these temperature fluctuations, making them well suited for laboratories storing sensitive reagents, enzymes, proteins, and biological samples.

Typical Stored Materials

The Fisher 13-986-247 is commonly used to preserve:

Research reagents
Antibodies
Enzymes
Proteins
Laboratory chemicals
Cell culture media
Diagnostic materials
Biological specimens
Quality control samples

Operating Costs & Energy Considerations

Operating costs are lower than those of ultra-low freezers because the refrigeration system maintains conventional laboratory freezer temperatures rather than -80°C. Maintaining adequate condenser ventilation, periodically cleaning the condenser, and manually defrosting the cabinet when frost accumulates will help maximize refrigeration efficiency and extend equipment life.

Specifications compiled from Fisher manufacturer literature and American Instrument Exchange product information.

Refurbishment & Testing Process

Every Fisher Laboratory Freezer 13-986-247 received by American Instrument Exchange undergoes a comprehensive inspection and temperature performance evaluation before shipment. Our technicians verify refrigeration performance, thermostat operation, compressor function, door gasket integrity, and cabinet condition. Temperature stability is confirmed using calibrated instrumentation, worn components are replaced as needed, and each freezer is thoroughly cleaned before delivery.

Laboratories building complete cold storage systems frequently purchase laboratory refrigerators, ultra-low freezers, biosafety cabinets, centrifuges, and cryogenic storage systems from American Instrument Exchange.

Shipping & Installation Considerations

The Fisher 13-986-247 ships by freight from American Instrument Exchange. Before installation, laboratories should verify doorway clearances, available floor space, electrical service, and adequate ventilation around the condenser. Allow the cabinet to reach operating temperature before loading valuable samples to ensure optimal performance.

Testing Procedures for Used and Refurbished Laboratory Freezers

Cold Storage Reliability from American Instrument Exchange

At American Instrument Exchange, every used and refurbished laboratory freezer we offer undergoes a comprehensive multi-point testing protocol to ensure optimal performance, temperature stability, and long-term reliability. Our rigorous testing procedures are designed to meet the demanding standards of biomedical, pharmaceutical, research, and clinical environments—so you can trust your freezer to protect your valuable samples and materials.

Why Testing Refurbished Laboratory Freezers Is Critical

Before any laboratory freezer is placed back into service, it must be carefully tested for:

Consistent temperature control and uniformity across internal zones
Compressor functionality and refrigeration system performance
Seal integrity and insulation efficiency to prevent temperature loss
Electrical safety and alarm system operation

Thorough testing minimizes the risk of temperature excursions, equipment failure, and product loss—especially for temperature-sensitive items like reagents, biological samples, and vaccines.

Our structured testing protocol ensures that all used and refurbished laboratory freezers meet or exceed manufacturer specifications and industry expectations.
