Refrigerators & Freezers

Models included: TSX Universal Series Upright Freezers (400, 500, 600, 700 Box Capacity Models)

The Thermo Scientific TSX Universal Series ultra-low temperature (ULT) freezers (-80°C) deliver next-generation sample protection, energy efficiency, and operational reliability for critical biological storage. Powered by updated Universal V-drive adaptive technology, the TSX Series dynamically adjusts compressor speeds based on laboratory usage patterns and door openings. Delivering 33% energy savings, 52% faster door-opening recovery, and quiet operation below 44 dB, it features an upgraded interactive touchscreen interface and universal voltage (100–230V) to support biobanking, clinical research, and biopharmaceutical workflows.

Technological Innovations & Core Capabilities

• Universal V-Drive Adaptive Cooling: Next-gen variable-speed compressors deliver 52% faster door-open recovery and up to 38% tighter thermal uniformity throughout the cabinet.
• Outstanding Energy & Environmental Efficiency: ENERGY STAR certified and ACT-labeled design using natural hydrocarbon refrigerants, consuming 33% less energy than legacy TSX models.
• Rapid Sample Access: Active pressure equalization port enables door re-entry in just 30 seconds (57% faster than previous models).
• High-Capacity & Secure Storage: Accommodates from 400 up to 700+ two-inch box capacities with insulated inner doors to prevent cold air loss during access.
• Interactive 7-Inch Touchscreen & Logging: Full-color interface featuring real-time parameter tracking, up to 15 years of event/temperature logging, user access controls, and USB/PoE data connectivity.
• Universal Voltage & Expanded Setpoints: Runs on universal voltage (100–230V, 50/60 Hz) with an expanded setpoint range from -40°C to -86°C.

Intended Applications

• Biobanking & Repository Management: Long-term archival of human biological specimens, genomic libraries, and clinical trial samples under strict thermal stability.
• Biopharmaceutical R&D & Production: Secure storage of temperature-sensitive biologics, vaccines, enzymes, and active pharmaceutical ingredients (APIs).
• Clinical & Diagnostic Laboratories: High-security storage of diagnostic specimens, patient blood derivatives, and pathology reagents requiring reliable -80°C preservation.

Thermo Scientific™ TSX Series high-performance -30°C auto defrost freezers are designed with features that support sample protection and sustainability objectives for the storage reagents, pharmaceuticals, vaccines, biological and other commonly used laboratory and clinical materials such as primers, siRNA molecules and fetal bovine serum (FBS) requiring -30°C. The Series’ V-drive technology is designed to provide temperature uniformity that continually adapts to user patterns, offering significant energy savings without compromising protection.
