Ultra-Low Temperature Freezers (-40°C, -86°C & -150°C)

Ultra-low temperature (ULT) freezers are engineered for the long-term preservation of biological samples, pharmaceutical compounds, enzymes, and other temperature-sensitive materials. Available in temperature ranges of -40°C, -86°C, and -150°C, these freezers deliver the precise, stable environments required by research, clinical, and biorepository applications.

Why Choose an Ultra-Low Temperature Freezer?

Standard laboratory freezers cannot maintain the extreme temperatures needed for many biological specimens. ULT freezers are specifically designed to:

  • Preserve cell lines, tissue samples, plasma, and nucleic acids for extended periods
  • Maintain consistent temperatures even during frequent door openings
  • Meet compliance requirements for clinical, pharmaceutical, and biobank facilities
  • Operate reliably with advanced alarm and monitoring systems

Available Temperature Ranges

  • -40°C Freezers: Ideal for enzyme storage, reagents, and select pharmaceutical products that do not require -86°C storage.
  • -86°C Freezers: The most widely used ULT freezer in research labs, biobanks, and hospitals. Perfect for long-term storage of biological samples, vaccines, and clinical specimens.
  • -150°C Ultra-Low Freezers: Also known as ultra-cold or cryogenic freezers, these are used for applications requiring near-cryogenic temperatures without the use of liquid nitrogen.
