Undercounter ULT Freezer

Undercounter ULT freezer with a space-saving design for remote clinical trials

Undercounter, Benchtop, Stackable Storage

The Stirling Ultracold SU105UE undercounter ultra-low temperature (ULT) freezer is ideal for bench-side personal storage or for use in areas where larger-volume ULTs are not suitable. This space-saving freezer delivers full-performance ULT storage for benchtop, stacked or undercounter configurations. It’s the ideal solution to optimize your laboratory floor plan, offering:
  • A space-saving design that doesn’t compromise storage capacity
  • A wide temperature range for transitioning biological materials to warmer temperatures
  • Secure, personalized storage in clinical settings
This stackable model uses the revolutionary free-piston Stirling engine technology found in our SU780XLE upright freezer, offering a highly reliable ULT storage solution with only a few moving parts, no oil and no compressors.
