TSX Series ULT -86°C Freezers

Thermo Scientific™ TSX Series ultra-low freezers are designed to meet the highest standards in reliability, sustainability and temperature management. At the heart of the TSX Series is V-drive technology, designed to adapt to user patterns, substantially reducing energy and HVAC costs without compromising performance. All TSX Series freezers are manufactured in a zero-waste facility and are built with natural refrigerants and water-blown foam insulation, compliant with the U.S. EPA’s Significant New Alternatives Policy (SNAP), the European Union’s F-Gas compliance and other sustainability standards.


  • No need to worry about where your samples are stored within the freezer.  With peak variation less than 5°C, your samples are protected and safely stored throughout the entire cabinet space. 
  • Long warm-up time from -50°C to -80°C: 5.05 hours
  • Quiet enough to reside directly in the laboratory, rather than in the hall. At just 45.5 dBA, the TSX Series’ sound level is comparable to a home refrigerator.
  • V-drives adaptive control is designed to detect usage patterns such as door openings when a higher compressor speed is needed and periods of stability where the compressor runs at a lower speed, saving energy without compromising protection

Wireless Monitoring Solution
