Compact, energy-efficient undercounter freezer with advanced Stirling technology, optimal for ultra-low storage.
Stirling Ultracold SU105UE Ultra-Low Undercounter FreezerFeatures
The Stirling Ultracold SU105UE Ultra-Low Undercounter Freezer is a compact ultra-low temperature freezer that is ideal for personal storage and situations where larger volume ULT freezers might otherwise remain half empty. The SU105UE delivers full performance ultra-low storage for undercounter, benchtop or stacked installation. These undercounter freezers feature a 105L (3.7 cu. ft.) cabinet that delivers stable, uniform -20°C to -86°C storage at a fraction of the operating cost of conventional cascade refrigeration systems. The SU105UE combines the performance of a unique free-piston Stirling engine with an efficient, thin-wall, non-CFC urethane foam and vacuum insulated cabinet. This permits high-performance, ultra-low temperature storage capacity in an undercounter, benchtop, or stacked cabinet configuration.
The Stirling integral control, alarm, and monitoring system includes an intuitive graphic user interface to display operating temperature, reserve cooling capacity, status functions, and performance metrics for field troubleshooting. Secure touchpad inputs permit access to and programming for all control functions and alarm setpoints. Using 100% natural refrigerants, the Stirling Ultracold SU105UE Undercounter Freezer stores more samples in a smaller footprint than comparable models.

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
