OPERON ELECTRIC FREEZER |
LIQUID NITROGEN FREEZER |
| Economic
efficiency |
It is available only with
the lower cost
electronic
connection. |
Expensive liquid nitrogen tank
and the liquid nitrogen
should
be supplemented consistently. |
| Safety |
It is safer from pollutants.
When blackout, it
secures safety with BACK UP SYSTEM if the
tempera-
ture goes up. |
It has a risk to be contaminated
by bacteria or fungi
inside
the tank |
| Accuracy |
Temperature difference between the upper
part
and the lower part inside
is ±5°C, so
the tempera-
ture is more even. |
The temperature of the lower
part inside the tank is
-196°C,
and the upper part is -70°C.
The temperature
difference
is huge. This has a significant
impact on
viability of stem cell. |
Conve-
nience |
Internal space can be used
efficiently
for keeping samples, and it is simple
to
perform work. |
Rack for keeping samples is
very inconvenient for sample
work because of the liquid
nitrogen tank’s structure, and
it
is difficult to use the space
inside the tank efficiently. |

Stem cell needs long-term
preservation for 10~20 years.
It's been stated on various
papers that cell preservation
using liquid nitrogen has lots
of problems.
OPERON products resolved
the above problems perfectly. |
