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

With peak variation less than 5 °C, your samples are protected and safely stored throughout the entire cabinet space. These freezers feature the longest warm-up time from –50 to –80 °C for an ultra-low freeze, as high as 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-drive's 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.

Newly re-designed touch-screen user interface with easy-to-use: set-up wizard, event log, temperature mapping and data downloads via a built-in USB port. Eliminate the need for a separate chart recorder with the touch-screen's datalogging and temperature mapping features, all exportable via a built-in USB port. Ergonomic design including comfortable door handle, eye-level touch-screen and shelf-level placement that don't require floor-level loading of racks. Four capacities (400, 500, 600 and 700 2-inch box) accommodate a variety of storage needs and lab footprint specifications. Compatible with most racking systems including a full range of Thermo Scientific™ racks for boxes, microplates, Thermo Scientific™ Matrix™ and Nunc CryoBank™ tubes. Security features including alarm settings, padlock-compatible doors and optional access card entry.

Natural refrigerants and water-blown foam insulation, making the TSX Series compliant with the U.S. Environmental Protection Agency's Significant New Alternatives Policy (SNAP), the European Union's F-Gas and other sustainability standards. Manufactured in an award-winning, zero-waste to landfill facility. Lower HVAC costs as a result of less heat emission into the environment.

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.
