-150°C CryogenicTemperature Freezer
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.

VIP® Plus™ Design
•SANYO V.I.P.® PLUS™ Cryogenic Series
without increasing the footprint.
•This design prevents the insulation layers from distortion and cracking that might occur due to temperature differences inside and out, and creates the most efficient insulation material available today.
•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 the “hot line” which prevents frost and condensation from forming on the gasket and mullion
•The newly developed refrigeration system and the freezer structure offer a quiet experimental environment.
• Achieves 50% higher energy conservation than conventionally insulated model.
Specially Designed Compressor for Cryogenic Temperatures
The refrigeration system is at the heart of producing cryogenic temperature freezing. In the process of developing various technical solutions in order to achieve and maintain cryogenic temperatures, SANYO designed the compressor specifically for this use. SANYO is a leading manufacturer of cryogenic temperature freezers.
