Thermo Scientific TSX40086A & TSX50086D Ultra-Low Temperature Freezers with V-Drive Adaptive Control

The Thermo Scientific TSX40086A and TSX50086D are advanced ultra-low temperature freezers designed for precise and energy-efficient storage of biological samples, essential in biotechnology, molecular diagnostics, and bioprocessing workflows. Featuring V-drive adaptive control technology, these ULT freezers dynamically adjust compressor output according to real-time conditions such as door openings and ambient temperature changes, ensuring consistent -80°C storage and rapid recovery, which is critical for maintaining sample integrity in gene editing, synthetic biology, and biomanufacturing environments.

Key technical features include:

• Temperature Range: -50°C to -86°C, ideal for cryogenic sample preservation and molecular cloning applications
• Refrigerants: Environmentally-friendly R290 (primary stage) and R170 + R290 mix (secondary stage) for efficient cooling performance
• Capacity & Dimensions:
• TSX50086D: 24.1 cu. ft. (682 L) volume, supports up to 500 two-inch boxes or 50,000 x 2mL vials, external dimensions 38x38x78”
• TSX40086A: 19.4 cu. ft. (549 L) volume, supports up to 400 two-inch boxes or 40,000 x 2mL vials, external dimensions 37x33x79”
• Power Consumption: Approximately 6.5 kWh/day at -70°C setpoint for energy-conscious laboratory operations
• Loading Capacity: Shelves support loads up to 205 lbs (93 kg), suitable for dense sample storage racks
• User Interface & Data Management: Integrated onboard data center allows easy access to operational records and setup without external hardware. Compatible with Smart-Vue for remote monitoring, supporting central lab oversight and audit trails critical in clinical and research environments.
• Ergonomic Design: Features easy-open handles and shelf-level loading to reduce strain during frequent access — vital for busy shared laboratory spaces

Extensively validated for operational stability with third-party temperature logging, the TSX series freezers guarantee reliable performance in critical biotechnology and biomedical research applications, including live-cell imaging sample storage, clinical diagnostics, and biopharmaceutical production pipelines. They are widely adopted in research facilities requiring ultra-low temperature preservation combined with energy efficiency and intelligent control systems.

This combination of capacity, adaptive compressor control, and integrated monitoring renders the Thermo Scientific TSX40086A and TSX50086D ultra-low freezers ideal for laboratories focused on long-term preservation of biological materials with stringent stability and traceability demands.
