Panasonic MDF series cryogenic freezer maintains uniform temperature of -150°C for stable, long-term preservation of cells and tissue.
Panasonic VIP® PLUS Cryogenic Series -150°C ultra-low temperature freezer achieves more storage capacity than a conventionally insulated
freezer without increasing footprint.

The newly developed refrigeration system and freezer structure offers a quiet environment.
Cryopreservation allows for storage of
biological materials at ultra low temperatures, while minimizing the level of freezing damage to cells.
An important factor to consider when
preserving cells or tissue at cryogenic
temperatures is to prevent amorphous
ice crystals from recrystallizing within
and outside the cells. These ice crystals
increase the degree of freezing damage
to cells.
-130°C is the recrystallization point of
pure water in the ultra-low temperature
zone. This is the temperature at which
amorphous ice crystals recrystallize.
Comparison of temperature distribution in a liquid nitrogen freezer (vapor phase) and Panasonic’s MDF-C2156VANC
mechanically refrigerated cryogenic freezer. Graph shows temperatures at different locations within the chamber. This
data demonstrates that 100% of the MDF-C2156VANC storage space maintains uniform storage temperatures safely
below -130ºC, while temperature in LN2 vapor system is dependent on storage location.
Uniform Cryogenic Temperatures
±5ºC uniformity in a mechanically refrigerated design promotes better top-tobottom uniformity than liquid nitrogen
vapor-phase storage, without the concern
of cross-contamination often associated
with liquid nitrogen liquid phase storage.
Thus samples maintained in an ultra-low
temperature freezer at -150ºC, far lower
than the recrystallization point, can be
semi permanently preserved.
Such preservation maintains vitrification
without further crystallization within and
outside cells.
Other recent findings show that preserving cattle sperm at -135°C is insufficient,
and that superconductivity experiments
require temperatures of at least -148ºC.

VIP® PLUS Design
Patented revolutionary vacuum insulation
cabinet construction reduces wall thickness and achieves more storage capacity
than a conventionally insulated freezer
without increasing the footprint.
• This design prevents the insulation
layers from distortion and cracking
that can occur over time due to
temperature differences inside and
out, and creates the most efficient
insulation material available today.

• The newly developed refrigeration
system and the freezer structure offer
a quiet experimental environment.
• Achieves 50% higher energy
conservation than conventionally
insulated model.
• Moisture condensation at the top
edges of the cabinet due to differences
in temperature inside and out causes
frost and icing problems, which may
reduce heat insulation efficiency and
obstruct door movements. These
obstructions are prevented by a
"warm zone" which prevents frost
and condensation
from forming on
the gasket and
mullion without
affecting interior
temperature.
