TSX Series Ultra-Low Freezers – Thermo Fisher Scientific
The TSX Series ultra-low temperature freezers from Thermo Fisher Scientific represent the next generation of laboratory storage, purpose-built to meet the strictest requirements for sample protection, energy efficiency, and environmental responsibility. Engineered with proprietary V-Drive technology, these freezers dynamically adjust compressor speed based on real-time activity, optimizing performance during frequent access or extended idle periods. This intelligent control achieves the perfect balance between high cooling performance, reduced noise, and remarkable energy savings.
With peak temperature variation as low as ±5°C and rapid recovery after door openings (under 30 minutes), TSX Series freezers deliver the thermal stability required to preserve sensitive biological materials, even in demanding lab environments. Their advanced insulation system, using SNAP-compliant natural refrigerants and water-blown foam, helps achieve a daily energy consumption of less than 9 kWh (depending on size), lowering both carbon footprint and HVAC load.
Ergonomically designed, the TSX freezers feature a user-friendly capacitive touchscreen that remains responsive when wearing gloves. Users can easily access event logs, temperature mapping, and system diagnostics via an integrated USB port, and the units come equipped with cloud monitoring capability through DeviceLink. Advanced security features such as customizable alarms, padlock-compatible doors, and optional RFID card access provide superior sample protection.
Available in four sizes—400, 500, 600, and 700 2-inch cryobox capacities—the TSX Series is designed to fit any footprint or storage need. With ultra-quiet operation (as low as 45.5 dBA), these freezers can be placed directly in the laboratory space without disturbance. Each model can be customized with a wide range of accessories, including LN2 or CO2 backup systems, chart recorders, lighting options, shelf kits, sliding drawer racks, and more.
ACT label–certified through MyGreenLabs and manufactured in a zero-waste-to-landfill facility, the TSX Series combines peak performance, sustainability, and durability. Backed by an exceptional 12-year compressor warranty (5 years full coverage + 7 years on the compressor), these freezers are the preferred choice for researchers, biobanks, hospitals, and laboratories committed to long-term, reliable ultra-low storage.
