Upright Ultralow Freezer

21cu.ft., touch screen ultra-low temperature freezer.
Protect your samples with steel-insulated inner doors for ultimate
temperature retention down to -86°C. Experience highly efficient variable speed
compressors for energy savings and enhanced system performance. Conduct
advanced data logging through intuitive touchscreen control—track real-time
temperature readings, export data, and capture trends with just a few taps. Dual
voltage compatibility ensures installation flexibility, with each unit including
both 115V and 230V power cords under a single part number. You can also rest
secure knowing your samples are guarded by a full array of alarms—no more
surprise temperature excursions. As a finishing touch, you’ll benefit from natural
hydrocarbon refrigerants for sustainability, energy efficiency, and long-term cost
savings. Together, these features are designed to push boundaries and harness
the full potential of the modern ULT.
