Safer, More Convenient
Than LN2
- Our cryogenic freezers include all
features, control and performance
attributes of the Ultima II Series
freezers, plus many important
advantages not available when
using LN2
- Stable cryogenic temperature of
-140°C and -150°C without LN2 as a
cooling medium
- Patented, single compressor, orbital
refrigeration system
- Top-to-bottom temperature
uniformity dramatically improved
when compared to LN2 vapor
- Lower operating costs than LN2
freezers of similar capacity
- 100% of interior space is usable,
with stored samples maintained
below critical temperature
- Ample interior volume with capacity
of up to 21,600 samples in Model
ULT-10140 and up to 14,400
samples in Model ULT-7150
(2 ml vials in boxes)
- Uses standard Thermo Scientific
Revco inventory racks and
fiberboard boxes
