Economic efficiency It is available only with
the lower cost electronic
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.
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.
