Thermo Scientific TLE Series Ultra-Low Upright Freezers from Thermo Fisher Scientific TLE30086A TLE30086D TLE30086V TLE40086A TLE40086D TLE40086V TLE50086A TLE50086D TLE50086V TLE60086A TLE60086D TLE60086V

New sustainability features include natural refrigerants and water-blown foam, compliant with many sustainability standards.

  • Thermo Scientific TLE Series ultra-low freezers feature four upright models, maximizing storage capacity from 30,000 up to 60,000 2mL vials.


  • Save up to 25% in energy usage and heat rejection over conventional refrigerant ultra-low freezers (1).
  • Meets validation protocols at -70°C and -80°C with strong peak variation and steady-state temperature variation.
  • A quiet sound output below 53 dBA, enables the freezer to come out of the hallway and into the lab.
  • Natural hydrocarbon refrigerants reduce system operating stresses promoting outstanding reliability and worry-free sample protection.
  • Designed for daily usage, recovers cabinet temperature 20% faster after opening the door (2).

User Friendly:

  • 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..
  • Newly re-designed, capacitive touch-screen user interface with easy-to-use: set-up wizard, event log, temperature mapping and data downloads via a built-in USB port.
  • On board temperature and event archive allows for quick access to freezer information.
  • Export a secure USB report and eliminate the need for a chart recorder.
  • 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 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.


  • (1) Internal data comparing 600 model at 11.2 kWh/day to UXF600 = 14.9 kWh/day. Data on file.
  • (2) Typical freezer test data based on internal testing in ambient temperature at 20°C; Typical standard validation protocol of +/-10°C.
