Thermo Scientific TSX40086 Ultra-Low Temperature Freezer
The Thermo Scientific TSX40086 Ultra-Low Temperature Freezer is a high-performance laboratory freezer engineered for biobanks, pharmaceutical manufacturers, biotechnology companies, hospitals, clinical laboratories, and research institutions requiring dependable long-term storage at temperatures as low as -86°C. Offering 19.4 cubic feet (549 L) of storage capacity with room for approximately 400 standard 2-inch storage boxes or 40,000 2 mL cryovials, the TSX40086 delivers outstanding sample protection while minimizing energy consumption and laboratory noise.
Part of the Thermo Scientific TSX Series, the TSX40086 incorporates V-drive variable-speed compressor technology, adaptive control software, high-performance vacuum insulation, a touchscreen controller, and natural hydrocarbon refrigerants to provide exceptional temperature uniformity, rapid recovery after door openings, and significantly lower operating costs than traditional cascade ultra-low freezers. Its quiet operation makes it well suited for installation directly within laboratory workspaces.
Many laboratories pair ultra-low freezers with laboratory refrigerators, biosafety cabinets, centrifuges, and cryogenic storage systems to build complete biological sample storage workflows.

Overview
The TSX40086 was engineered to provide dependable long-term storage for irreplaceable biological materials while dramatically reducing energy consumption compared to conventional cascade ultra-low freezers. Thermo Scientific's V-drive technology continuously adjusts compressor speed according to laboratory usage patterns, increasing cooling output during frequent door openings while reducing power consumption during periods of stability.
Unlike older fixed-speed refrigeration systems that operate continuously at maximum output, the TSX40086 optimizes compressor performance in real time. This improves temperature recovery, reduces compressor wear, lowers HVAC demands, and helps maintain exceptional temperature uniformity throughout the cabinet. Quiet operation also allows the freezer to remain inside the laboratory rather than requiring installation in a separate equipment room.
Common Applications
The TSX40086 is commonly used for long-term storage of DNA, RNA, plasma, serum, tissue samples, stem cells, bacterial cultures, viral collections, vaccines, monoclonal antibodies, proteins, microbiology isolates, clinical specimens, forensic evidence, pharmaceutical reference materials, and valuable research samples requiring storage at temperatures as low as -86°C.

Refurbishment & Testing Process
Every Thermo Scientific TSX40086 received by American Instrument Exchange undergoes a comprehensive inspection before shipment. Our technicians verify temperature accuracy using calibrated monitoring equipment, inspect the refrigeration system, V-drive compressor operation, touchscreen controller, alarm functions, battery backup, door gaskets, and cabinet integrity. Each freezer is thoroughly cleaned, performance tested, and verified to maintain temperature within manufacturer specifications before shipment.
Laboratories purchasing ultra-low freezers frequently also purchase laboratory refrigerators, cryogenic storage tanks, biosafety cabinets, and centrifuges from American Instrument Exchange.
Shipping & Installation Considerations
The TSX40086 ships by freight from American Instrument Exchange. Before installation, verify adequate electrical service, sufficient ventilation, and floor loading capacity. Allow the freezer to reach its operating temperature before loading valuable samples. Organizing inventory using compatible storage racks and minimizing door-open times will help maximize temperature stability and sample protection.
Frequently Asked Questions
How many sample boxes will the TSX40086 hold?
The TSX40086 accommodates approximately 400 standard 2-inch storage boxes, providing storage for roughly 40,000 standard 2 mL cryovials, depending on rack configuration.
How is the TSX40086 different from older Thermo Revco ultra-low freezers?
The TSX40086 uses Thermo Scientific's V-drive variable-speed compressor technology instead of a traditional fixed-speed cascade system. This improves energy efficiency, reduces operating noise, enhances temperature recovery after door openings, and lowers HVAC costs while maintaining outstanding sample protection.
Why does the TSX40086 have only two inner doors?
The two insulated inner doors reduce cold air loss during sample retrieval while simplifying access to stored inventory. Combined with high-performance insulation and adaptive compressor control, this design helps maintain stable temperatures throughout the cabinet.
How is the freezer tested before shipment?
Every refurbished Thermo Scientific TSX40086 is inspected and temperature tested by American Instrument Exchange technicians. Refrigeration performance, controller operation, alarm systems, door seals, and overall cabinet functionality are verified before shipment.
