Thermo Scientific TSU400A Upright Ultra-Low Temperature Freezer −85°C Capacity 28.8 cu ft
Product Description
The Thermo Scientific TSU400A is a high-performance upright ultra-low temperature freezer designed for reliable long-term storage of biological and chemical samples at temperatures ranging from −50 °C to −85 °C. Widely utilized in research laboratories, clinical diagnostics, and biobank facilities, this ULT freezer features advanced insulation technology combining vacuum-insulated panels with water-blown foam to drastically reduce heat intrusion and ensure uniform cabinet temperatures.
Key features include:
- Capacity: Available in 28.8 cu ft (815 L) or 19.4 cu ft (548 L) models supporting 60,000 or 40,000 vial capacity respectively, suitable for large-scale biotechnology and molecular diagnostics storage demands.
- Space-Efficient Design: Compact footprints of 11.38 sq ft (1.06 sq m) or 8.46 sq ft (0.79 sq m) optimize laboratory floor space without sacrificing volume.
- Temperature Stability: Insulated inner doors and reinforced shelving minimize temperature fluctuation during frequent sample access, critical for preservation in live-cell imaging and synthetic biology workflows.
- User Interface: Integrated touchscreen controller enables real-time monitoring of temperature history, alarm management, and event logging with USB export for compliance documentation and research audit trails.
- Energy and Performance Modes: Dual operating configurations provide flexibility for laboratories prioritizing either energy efficiency or cooling performance, adaptable to diverse bioprocessing requirements.
- Validated Performance: Each unit undergoes third-party temperature validation, confirming consistent maintenance of target ultra-low temperatures for over 24 hours, ensuring security in biomanufacturing and gene editing reagent storage.
Power specifications include options for 208-230 V, 60 Hz, 9 amps or 115 V, 60 Hz, 16 amps, supporting standard laboratory electrical systems. The freezer’s robust construction and temperature precision make it critical equipment in synthetic biology research centers, molecular cloning workflows, and biopharmaceutical production pipelines.
This TSU Series freezer supports essential biotechnological and clinical applications requiring stringent temperature-controlled environments, making it a popular choice among molecular biology researchers and biomedical engineers for ultra-low temperature storage of sensitive biomaterials.
