Model U101 personal-sized freezer allows researchers to keep biopsies, cells and other samples safely stored in their own lab, despite any shortage of lab space. This compact upright, with 3.6 cu/ft capacity, can be placed either on or under the bench, and is now available with a stacking kit. Lock and key are provided for the outer door, as is a 4-digit password, and a lock-plate over the power on-off switch. The energy efficient, low noise, 㫮 C freezer measures only 32.7× 35.4× 22.3, yet can hold 60 two-inch boxes for vials or tubes. Patented Tollesbury Technology reduces "cycle-on" time by 40-50%, lowering power consumption and increasing compressor efficiency.
