The SU105U combines the performance of a unique free-piston StirlingTM engine with an efficient, thin-wall, non-CFC urethane foam and vacuum insulated cabinet. This permits high-performance ultra low storage capacity in an undercounter, benchtop or stacked cabinet configuration.

Energy Efficient

The ultra low freezer operates on standard 115V, 60Hz AC. Engine power demand is typically 150 watts, nominal. The Humm™ self-modulating cooling system demands only 230 watts at ambient start-up and decreases for most efficiency at its lowest operating temperature.

MIDSCI brings you the best in ultracold freezer equipment with the primary goal to save your lab time and money and accelerate the consistency of your life science experiments and the reproducibility of your data generation and publication. Call us for a quote today.
