Fisher Scientific Isotemp 13-986-233G General Purpose Laboratory Refrigerator
Laboratories storing reagents, media, biological specimens, pharmaceuticals, controls, and other temperature-sensitive materials need refrigeration designed for scientific use rather than household food storage. The Fisher Scientific Isotemp 13-986-233G General Purpose Laboratory Refrigerator provides dependable refrigerated storage in a spacious 31 cubic foot cabinet, making it well suited for biotechnology companies, pharmaceutical manufacturers, universities, hospitals, clinical laboratories, and industrial research facilities.
The Fisher 13-986-233G operates from 1°C to 12°C and provides approximately ±3°C temperature stability for everyday laboratory storage applications. Its large glass-door cabinet allows personnel to identify stored materials before opening the refrigerator, helping reduce unnecessary door-open time and improve workflow in laboratories with frequently accessed inventory.
Refurbished and performance tested by American Instrument Exchange
90-day warranty included
Overview
The Fisher Scientific Isotemp 13-986-233G is designed for laboratories that need substantial refrigerated storage capacity without the specialized configuration of a blood bank, pharmacy, or chromatography refrigerator. Its 31 cubic foot interior provides room for large inventories of commonly used laboratory materials while supporting organized, accessible storage.
Two glass doors allow laboratory personnel to locate samples and reagents before opening the cabinet. This improves inventory visibility and can reduce the duration of door openings, helping the refrigerator return to its target temperature more efficiently during busy laboratory operations.
The stainless steel interior provides a durable, corrosion-resistant storage chamber that is easier to clean than many painted interiors. An automatic defrost system reduces routine maintenance, while the digital display and alarm functions help users monitor cabinet conditions throughout daily operation.
Common Applications
The Fisher Scientific 13-986-233G is commonly used for refrigerated storage of laboratory reagents, cell culture media, antibodies, enzymes, proteins, biological specimens, diagnostic materials, pharmaceutical products, analytical standards, quality-control samples, and other research materials requiring controlled temperatures.
Ideal Laboratory Types
The 13-986-233G is well suited for:
Biotechnology companies
Pharmaceutical manufacturers
Academic research laboratories
Clinical laboratories
Hospitals and medical research facilities
Environmental testing laboratories
Government research facilities
Industrial research and development laboratories
Quality-control and quality-assurance laboratories
Its combination of large capacity and straightforward laboratory refrigeration makes it particularly useful for facilities that need centralized storage for materials accessed regularly throughout the workday.
Why Choose the Fisher Scientific 13-986-233G?
The Fisher 13-986-233G offers a practical balance of capacity, visibility, durability, and temperature control. Its two-door configuration and large interior make it easier to organize substantial laboratory inventories, while the glass doors help users find materials before opening the cabinet.

Refurbishment and Testing Process
Every Fisher Scientific Isotemp 13-986-233G offered by American Instrument Exchange undergoes a comprehensive inspection and performance evaluation before shipment. Our technicians test the refrigerator with calibrated temperature-recording equipment to verify the accuracy of the temperature controls and digital readout.
The refrigeration system, compressor, fans, automatic defrost operation, alarm functions, electrical components, glass doors, hinges, gaskets, shelving, and cabinet condition are inspected. Hardware and worn components are repaired or replaced as necessary, and the refrigerator is thoroughly cleaned before being prepared for shipment.
The Fisher Scientific 13-986-233G ships by freight from American Instrument Exchange. Before delivery, verify doorway clearances, hallway widths, available floor space, and access to the required 115V, 60 Hz electrical service.
The refrigerator should be installed on a level surface with adequate clearance for ventilation around the refrigeration system. After installation, allow the cabinet to reach and stabilize at the selected operating temperature before loading valuable laboratory materials.
