  • 0.9 cubic feet storage volume
  • Temperature range from -20°C to -86°C  
  • 90-day warranty

The Stirling Ultracold Shuttle ULT-25N ultralow freezer is a portable, shippable -86°C model designed for applications that have very limited space or tight power constraints. The Stirling ULT-25N is compact, reliable, energy-efficient that can be used for cold-chain management or even transport of biological specimens. Incorporates free-piston engine technology with a micro-fluid cooling media that eliminates conventional refrigeration or a cascade compressor system. A vehicle adapter allows the Stirling ultralow ULT-25N to be used in applications that require portability, such as pharmaceutical distribution. Other uses include pathology laboratories, tissue banks, regenerative medicine, and other applications related to clinical or diagnostic medicine.

All of our equipment is used and reconditioned. Our technicians verify the accuracy of temperature controls and readouts of all freezers, making sure that the units hold temperature to within the manufacturer specified tolerance. We replace any hardware or parts as is necessary and if needed replace refrigerant. We clean all freezers thoroughly prior to shipment.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
