(Vacuum Insulation Panel)
VIP panel is the innovative insulation component
developed and manufactured by SANYO.
VIP panels contain densely packed, open cell
foam insulation under vacuum.
This configuration dramatically enhances the insulation capability of the
freezer while reducing the wall thickness. This in turn leads to greater
interior volume and structural stability.
Ideal for preservation of reagents, research materials and medicines,
SANYO preservation systems employ microprocessor control to
maintain high-precision temperature environment, not being affected by
ambient temperature,
minimizing uneven temperature distribution
within the chamber, and a temperature rise during defrosting.
World’s lowest -152˚C freezer ensures
stable cell and tissue preservation.
An important factor to consider when preserving
cells or tissue at ultra-low temperatures is to
prevent amorphous ice crystals from
recrystallizing within and outside the cells.
Samples that are maintained in an ultra-low
temperature freezer at -152˚C which is far lower
than the recrystallization point (-130˚C for pure
water) can be preserved semi-permanently.
Preservation at ultra-low temperatures maintains
vitrification without crystallization occurring inside
and outside cells. In contrast to conventional liquid
nitrogen preservation containers, freezer
preservation has numerous advantages: no
sample contamination, no sudden liquid eruptions
as well as low operational costs. SANYO freezers
make long-term storage below the recrystallization
point easier and more stable than ever before.
