TDE Series Ultra-Low Temperature Freezers

Part of the Standard Performance (STP) family, Thermo Scientific™ TDE Series ultra-low temperature freezers, powered by H-drive, feature four upright models, maximizing storage capacity from 30,000 up to 60,000 2mL vials. The TDE Series is a sustainable and reliable solution with ultimate sample security and operational savings for every lab.
From our first ULT freezer in 1940 to today, the combined experience of REVCO, Forma Scientific, Jewett, Harris, and other families of products continues to drive our ability to deliver industry-leading innovations that help accelerate science and health care.

Features and Benefits


  • Powered by H-drive’s hydrocarbon technology, these systems save up to 25% in energy usage and heat rejection over conventional refrigerant ultra-low freezers1
  • Designed for daily usage, recovers cabinet temperature 20% faster after opening the door.2
  • A quiet sound output below 53 dBA, enables the freezer to come out of the hallway and into the lab
  • Meets +/-10°C validation protocols at -80°C with strong peak variation and steady-state temperature variation
  • Natural hydrocarbon refrigerants reduce system operating stresses promoting outstanding reliability and worry-free sample protection

User Friendly

  • The H-drive Information Center (HIC) combines easy to read temperature with simple capacitive touch buttons in a 5.6” display
  • Four capacities (300, 400, 500 and 600 2-inch box) to accommodate a variety of storage needs and lab footprint specifications
  • All models contain four inner doors allowing for easy sample access without exposing greater freezer content to ambient conditions
  • Improved customer convenience with new ergonomically designed handle, high contrast eye-level display, and comfortable easy-access shelf locations.
  • 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 and padlock-compatible doors


  • Manufactured in an award-winning, zero-waste to landfill facility
  • Lower HVAC costs as a result of less heat emission into the environment
  • Natural refrigerants and water-blown foam insulation, making the 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

Get Connected

The Thermo Scientific™ DeviceLink™ Connect remote monitoring solution helps provide peace of mind by enabling you to keep track of your equipment anytime, anywhere. This system supports independent sensors to monitor your instrument, but it can also be connected via serial port directly to the instrument, harnessing the on-board telemetry data, alarms, and events. All information is transmitted to the Thermo Fisher Connect cloud platform where you have 24/7 access to the information via InstrumentConnect’s web- and mobile-based applications.
