What Is an Ultra-Low Temperature Freezer?

Your Guide to -86°C Lab Freezers for Critical Laboratory Storage

An ultra-low temperature freezer (ULT freezer) is a specialized piece of laboratory equipment designed to store sensitive biological and chemical samples at extremely low temperatures -typically around -80°C. These freezers are essential for long-term sample preservation in research, clinical, and industrial settings.

Key Applications of ULT Freezers

Ultra-low temperature freezers are widely used in:

ULT Freezer Types: Upright vs Chest-Style (Horizontal)

ULT freezers are available in two formats:

  • Upright ULT Freezers – Designed for easy access and efficient use of lab space due to the small footprint. Ideal for frequently accessed samples.
