"The Stirling Ultracold is an excellent freezer. We have had it for two years now and it has been great for us. Keeps -70C even when I am accessing our frozen stocks frequently through the day. It is also very quiet as well. Our maintenance department likes that it uses less power than a standard freezer. I would recommend this freezer to all labs."

The SU780XLE is one of the industry's best performing, most energy-efficient ultra-low freezer. As our next generation upright ULT freezer, the SU780XLE delivers enhanced system reliability, sample integrity, and lowest energy use compared to its award-winning predecessor, the SU780UE. Your samples will be safer than ever because there are no compressors, and proven Stirling engine technology is used with continuous modulation that maintains unmatched temperature stability. The SU780XLE has the largest storage volume per sq. ft. of floor space of any available freezer, and uses a universal power system allowing an input voltage range of 100v to 240v (±10%) at either 50 or 60hz with minimal current surge.
