Our Ultima II series cryogenic storage chest freezer ULT7150-9-M is manufactured by Thermo Scientific Revco with 6.8 cu. ft. capacity. This cryogenic freezer maintains uniform temperature of -150 C, safely below the -130 C glass transition temperature of water. Top-to-bottom temperature uniformity is dramatically improved when compared to LN2 vapor. The advanced microprocessor control system with touchpad data entry and digital display allows for intuitive operation. Set point security system for main power and alarm locks in temperature and alarm set points allows for increased sample protection. This model uses standard Thermo Scientific inventory racks and fiberboard boxes (sold separately).
