Description

Designed for long-term storage of biologicals at uniform temperatures of -140°C, safely below the -130°C glass transition temperature. Cell viability is improved because biologically relevant, thermally driven reactions are not known to occur. Safer, more convenient than LN₂—lower operating costs, too. Plus, top-to-bottom temperature uniformity is dramatically improved when compared to LN2 vapor.

Capacity: 10.3 cu. ft. (292L)
100% of interior space is usable, with stored samples maintained below critical temperature
Ample interior volume with capacity of up to 21,600 samples
Uses standard Revco inventory racks and fiberboard boxes

Refrigeration System

Exclusive mixed refrigerant autocascade with a single, orbital refrigeration compressor, air cooled
Downfeed evaporator for most efficient refrigerant flow
High-capacity air-cooled condenser with dual condenser fans, aerodynamically shaped fan blades
Washable condenser filter keeps fins free of dust to maintain peak cooling efficiency; no tools required for removal
