Thermo Scientific™ TSX Universal Series Ultra-Low Freezer – 19.4 cu. ft.

The Thermo Scientific™ TSX40086FA2IDREP Ultra-Low Freezer delivers exceptional performance, durability, and energy efficiency for laboratories requiring secure long-term storage of high-value biological materials. With a 19.4 cu. ft. capacity and a stable temperature range of –40°C to –86°C, this freezer combines advanced V-Drive technology, robust construction, and precision temperature control to safeguard critical samples.

Built in ISO 13485:2016 facilities, each unit undergoes over 10,000 hours of intensive testing and strict end-of-line quality verification. The universal V-Drive technology intelligently adapts compressor speed to user activity, ensuring peak efficiency and consistent temperature recovery after door openings—while maintaining less than 4°C variation throughout the cabinet.

A compact footprint, universal voltage, ergonomic handle, and whisper-quiet operation make this unit ideal for research, clinical laboratories, biobanks, and pharmaceutical facilities. Advanced insulation, ENERGY STAR® certification, and rapid cooldown time (reaching –80°C in under 5 hours) further enhance reliability and performance.

⚠️ Safety Notice

Install the freezer on a stable, ventilated surface and ensure clearance for airflow. To maintain optimal performance, keep the solid door sealed tightly using the ergonomic handle and avoid prolonged door openings. Because the unit operates on manual defrost, monitor frost accumulation and schedule defrosting to maintain temperature accuracy. Verify alarms regularly and follow all manufacturer recommendations for sample protection and equipment maintenance. Disconnect power before performing any service.
