Temperature control and handling limitations of dry ice storage can risk the viability of your valuable samples in the field, while compressor-based ULT freezers are too unwieldy and unreliable for deployment at remote sites. The revolutionary ULT25NEU was designed to solve these problems. With its compact and field-proven, free-piston Stirling engine technology, it brings portable, precisely controlled ULT storage anywhere there is a need for patient care, testing or specimen collection.
