Overview

The Thermo Scientific TSX70086A represents one of the largest configurations in the TSX Series of upright ultra-low temperature freezers. Designed for laboratories maintaining extensive biological sample collections, the TSX70086A offers substantially greater storage capacity than smaller 400-, 500-, and 600-box models.

Its 33.5 cu. ft. chamber accommodates up to 700 standard 2-inch cryoboxes. With compatible 100-place cryoboxes, this provides a theoretical capacity of approximately 70,000 individual cryovials. This storage density makes the freezer particularly useful for biobanks, pharmaceutical development programs, large academic research facilities, and centralized sample repositories.

A defining feature of the TSX70086A is Thermo Scientific's V-drive refrigeration technology. Unlike traditional fixed-speed compressor systems, V-drive adjusts refrigeration operation in response to changing conditions. The system can increase cooling output following door openings or other thermal disturbances and reduce compressor activity when temperatures are stable.

This adaptive approach helps balance temperature recovery, energy consumption, compressor operation, and laboratory noise.

The TSX70086A also incorporates a touchscreen interface that provides convenient access to operating information, alarm settings, event records, and temperature data. Built-in USB functionality supports data retrieval for equipment monitoring, documentation, and troubleshooting.

For laboratories replacing older ultra-low freezers, a refurbished TSX70086A can provide modern refrigeration technology and substantial sample capacity at a lower acquisition cost than comparable new equipment.

Common Applications

The Thermo Scientific TSX70086A is designed for long-term ultra-low temperature storage of compatible biological and research materials, including DNA, RNA, cell lines, stem cells, plasma, serum, tissue specimens, microbial cultures, proteins, enzymes, antibodies, pharmaceutical compounds, and archived research samples.

Common applications include biobanking, molecular biology, genomics, proteomics, pharmaceutical research, biotechnology development, vaccine research, microbiology, clinical research, and biomedical sample preservation.

Its large storage capacity makes the TSX70086A particularly valuable for facilities managing extensive sample collections, longitudinal research studies, pharmaceutical reference materials, and centralized biological repositories.

Specific storage temperatures should always be determined by the requirements of the individual materials being preserved.

Ideal Laboratory Types

The TSX70086A is particularly well suited for biotechnology companies, pharmaceutical research and development facilities, biobanks, university core laboratories, academic research institutions, hospitals, clinical research organizations, molecular biology facilities, public health laboratories, and government research institutions.

Laboratories maintaining large numbers of samples can benefit from consolidating inventory into high-capacity ultra-low temperature freezers. Compared with distributing an equivalent sample collection across numerous smaller cabinets, consolidation may reduce equipment count, maintenance requirements, and monitoring complexity.

The TSX70086A is also an attractive option for facilities seeking to modernize older ultra-low freezer inventories with more energy-efficient equipment.

Temperature Recovery & Uniformity

Reliable temperature recovery is essential when storing valuable biological samples at approximately -80°C. Each time an ultra-low freezer is opened, warmer laboratory air enters the cabinet and creates an additional refrigeration load.

The TSX70086A uses V-drive variable-speed refrigeration to respond dynamically to these changing conditions. When increased cooling capacity is needed, compressor operation adjusts to help restore the chamber to its operating setpoint.

Thermo Scientific reports approximately 31 minutes of door-opening recovery for the TSX70086A under its published test conditions at a -80°C setpoint and 20°C ambient temperature.

The freezer's high-performance insulation and insulated inner compartments help reduce temperature disturbances during routine sample access.

Thermo's published performance data also indicates approximately 339 minutes of warm-up time from -80°C to -50°C under specified test conditions. This figure provides useful context for the freezer's thermal performance but should not replace appropriate emergency monitoring and backup-storage procedures.

Actual temperature uniformity and recovery will depend on freezer loading, ambient temperature, door-opening duration, sample arrangement, operating setpoint, and refrigeration-system condition.

Sample Storage Recommendations

With capacity for up to 700 standard 2-inch cryoboxes, effective inventory management is especially important in the TSX70086A.

Compatible freezer racks can organize cryoboxes by project, researcher, sample type, collection date, or department. Using 100-place cryoboxes, the freezer can theoretically accommodate approximately 70,000 individual cryovials, although actual capacity depends on rack and box configuration.

Laboratories should establish clearly labeled rack positions and maintain an accurate sample inventory. This reduces the time required to locate materials and helps minimize unnecessary door openings.

Frequently accessed samples should be organized so they can be retrieved quickly without disturbing other storage areas. Insulated inner compartments should be opened only as necessary during sample retrieval.

For valuable or irreplaceable sample collections, laboratories should maintain appropriate temperature monitoring, alarm notification, emergency power procedures, backup ultra-low freezer capacity, and documented sample-transfer plans.

Key Specifications

Specifications are based on Thermo Scientific's published TSX70086A manufacturer literature. Performance figures represent manufacturer test conditions and may vary in actual laboratory operation. Other electrical configurations, including the TSX70086D, have different power requirements.

Energy Efficiency & Operating Costs

Energy consumption is a major consideration when selecting an ultra-low temperature freezer, particularly for laboratories operating multiple units continuously.

The Thermo Scientific TSX70086A uses V-drive variable-speed refrigeration to adjust cooling output according to operating conditions. Rather than relying exclusively on fixed-speed compressor cycling, the system responds to changes in thermal demand.

Thermo Scientific reports typical energy consumption of approximately 10.2 kWh per day for the TSX70086A at a -80°C setpoint and 20°C ambient temperature under its published test conditions.

For a freezer accommodating up to 700 cryoboxes, this provides substantial storage capacity relative to daily energy consumption.

Energy-efficient refrigeration can also reduce the amount of heat released into the laboratory environment, potentially lowering HVAC demand in facilities containing multiple ultra-low freezers.

The TSX70086A additionally incorporates natural hydrocarbon refrigerants and high-performance insulation, supporting Thermo Scientific's emphasis on environmentally responsible cold-storage technology.

Actual operating costs depend on electrical rates, ambient conditions, setpoint, sample loading, ventilation, maintenance, and door-opening frequency.

Refurbishment & Testing

This Thermo Scientific TSX70086A ultra-low temperature freezer is supplied used and refurbished by American Instrument Exchange.

Before shipment, AIE technicians inspect, clean, and performance test the freezer to verify proper operation. Ultra-low temperature equipment is tested using NIST-traceable temperature probes and data logging equipment as appropriate to evaluate its ability to reach and maintain ultra-low operating temperatures.

The refrigeration system and V-drive compressor operation are evaluated along with the touchscreen controller, temperature display, alarms, monitoring functions, door hardware, inner doors, gaskets, insulation, shelving, electrical components, and cabinet.

Temperature performance is monitored over time rather than simply confirming that the freezer reaches its setpoint. This allows technicians to evaluate sustained refrigeration performance and identify problems that may not be apparent during initial cooldown.

Worn or defective components are repaired or replaced as necessary during refurbishment. The freezer interior and exterior are thoroughly cleaned before shipment.

Customers with specific testing or documentation requirements are encouraged to discuss those needs with American Instrument Exchange before shipment. When practical, AIE can accommodate application-specific temperature testing requests.
