Fisher Scientific Isotemp 13-986-150 Explosion-Proof Laboratory Freezer

Laboratories that operate in hazardous environments require equipment designed to do more than simply maintain frozen temperatures. When flammable vapors may be present both inside the storage cabinet and in the surrounding room, an explosion-proof laboratory freezer provides an additional level of protection beyond a standard laboratory or flammable material storage freezer. The Fisher Scientific Isotemp 13-986-150 Explosion-Proof Laboratory Freezer is specifically engineered for these demanding environments, providing dependable -12°C to -20°C storage while meeting the requirements for installation in designated hazardous locations.

With approximately 20.6 cubic feet (583 L) of storage capacity, the 13-986-150 is an excellent choice for chemical manufacturers, pharmaceutical facilities, petrochemical laboratories, universities, government research facilities, and industrial laboratories where ignitable vapors may be present. Unlike conventional laboratory freezers, this model features both a spark-free interior and explosion-proof exterior electrical components, allowing it to be safely installed in Class I, Division 1, Group C and D hazardous locations when properly hardwired.

Many laboratories install explosion-proof freezers alongside chemical fume hoods for handling volatile solvents, laboratory refrigerators for refrigerated chemical storage, biosafety cabinets for biological sample preparation, and laboratory freezers for non-hazardous frozen storage.

Fisher Scientific 13-986-150 Overview

The 13-986-150 is intended for laboratories where hazardous concentrations of flammable gases or vapors may exist in the surrounding environment. Unlike a flammable material storage freezer—which protects against ignition of vapors inside the cabinet—an explosion-proof freezer also protects against ignition from electrical components located outside the storage compartment.

Electrical controls, thermostat components, relays, and wiring are housed within explosion-proof enclosures, while the refrigeration system is engineered for installation in classified hazardous areas. This allows laboratories to safely store volatile chemicals requiring frozen temperatures while complying with facility safety requirements for hazardous locations.

Common Applications

The Fisher Scientific 13-986-150 is commonly used for storing:

Flammable laboratory solvents
Organic standards
Volatile chemical reagents
Petroleum samples
Pharmaceutical compounds
Chemical reference materials
Hazardous laboratory chemicals
Industrial process samples

Ideal Laboratory Types

The 13-986-150 is well suited for:

Chemical manufacturing facilities
Petrochemical laboratories
Pharmaceutical production facilities
Government research laboratories
University chemistry departments
Environmental testing laboratories
Industrial R&D facilities
Hazardous materials laboratories

Laboratories operating in classified hazardous environments benefit from the additional protection provided by a true explosion-proof freezer.

Why Choose an Explosion-Proof Freezer?

One of the most common points of confusion is the difference between flammable material storage freezers and explosion-proof freezers.

A flammable material storage freezer is designed to prevent ignition of flammable vapors inside the cabinet. An explosion-proof freezer, however, is engineered for installation in hazardous locations where ignitable vapors may also exist outside the cabinet. To accomplish this, electrical controls and wiring are enclosed in explosion-proof housings, and the unit must be permanently hardwired according to applicable electrical codes.

If your laboratory is located in a classified hazardous area, an explosion-proof freezer is typically the appropriate choice.

Typical Stored Materials

The Fisher Scientific 13-986-150 is commonly used for storing:

Organic solvents
Flammable reagents
Petroleum products
Chemical standards
Industrial process samples
Volatile pharmaceutical compounds
Analytical reference materials

Operating Costs & Energy Considerations

The 13-986-150 operates at conventional laboratory freezer temperatures, making it considerably less expensive to operate than an ultra-low freezer. Manual defrost eliminates automatic warming cycles that could affect temperature-sensitive chemicals, while routine condenser cleaning and periodic manual defrosting help maximize refrigeration efficiency. Because this freezer is designed for hazardous locations, installation should always be performed by qualified personnel familiar with applicable electrical and fire safety codes.

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

Refurbishment & Testing Process

Every Fisher Scientific 13-986-150 received by American Instrument Exchange undergoes a comprehensive inspection before shipment. Our technicians verify refrigeration performance, thermostat operation, compressor function, cabinet integrity, shelving, and door gasket condition. Temperature performance is confirmed using calibrated instrumentation, and the freezer is thoroughly cleaned before shipment. Because explosion-proof equipment is installed in specialized environments, customers should have final installation and electrical connection completed by qualified personnel in accordance with local codes.

Laboratories outfitting hazardous chemical storage areas frequently purchase chemical fume hoods, laboratory refrigerators, laboratory freezers, biosafety cabinets, and centrifuges from American Instrument Exchange.

Shipping & Installation Considerations

The Fisher Scientific 13-986-150 ships by freight from American Instrument Exchange. Before installation, laboratories should verify doorway clearances, available floor space, and electrical service. Because this freezer is intended for hazardous locations, it must be permanently hardwired by a qualified electrician in accordance with local electrical codes and facility safety requirements. Adequate ventilation around the condenser should also be maintained for optimal refrigeration performance.

Frequently Asked Questions

How is an explosion-proof freezer different from a flammable material storage freezer?

A flammable material storage freezer protects against ignition of vapors inside the cabinet. An explosion-proof freezer also protects against hazardous vapors outside the cabinet, allowing installation in classified hazardous locations.

Can this freezer be plugged into a standard wall outlet?

No. The 13-986-150 is supplied without a power plug and must be permanently hardwired by a qualified electrician in accordance with applicable electrical codes.

What types of laboratories use explosion-proof freezers?

They are commonly used in chemical manufacturing, petrochemical facilities, pharmaceutical production, hazardous materials laboratories, and other environments where ignitable vapors may be present.

How is the Fisher Scientific 13-986-150 tested before shipment?

Every refurbished Fisher Scientific 13-986-150 is inspected and temperature tested by American Instrument Exchange technicians. Refrigeration performance, temperature stability, cabinet integrity, and overall operation are verified before shipment. Final electrical installation should always be performed by qualified personnel.

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.
