Description
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. Boasting the widest temperature range in the industry, the SU105UE undercounter ULT lab freezer is perfect for warming up samples and biologics in stages. It’s the ideal solution to optimize your laboratory floor plan, offering:
