New Ultracold Freezer May Replace Liquid Nitrogen Cryopreservation Systems

The SANYO (Etten-Leur, The Netherlands) MDF-C2156VAN freezer provides a stable and uniform environment that maintains a constant -150 °C. As this low temperature is below the recrystallization point of water, the SANYO MDF-C2156VAN addresses the long-term storage requirements associated with stem cell research and cell therapy, regenerative medicine, biomedical research, and tissue and cell banks.

The new line of freezers incorporates Sanyo’s proprietary VIP PLUS insulation panels, which reduce the wall thickness from 175 mm to 135 mm. This allows for up to 25% more storage capacity compared with a conventionally insulated freezer without increasing the footprint. The resulting capacity of 231 liters will accommodate up to 14,000 two-milliliter cryostorage tubes.

Complementing the benefits of VIP PLUS insulation, a double lid gasket helps maintain internal temperature stability by preventing cold air loss. The results are lower running costs, greater ease of use and accessibility to stored samples, and no risk of contamination from liquid nitrogen.

The internal temperature is accurately controlled and monitored by an advanced microprocessor controller and specially designed graphic display. As a safety feature to guard against power outages, the freezer is equipped with a liquid nitrogen back-up system as standard, which allows connection to a separate supply vessel.

The MDF-C2156VAN freezer is a worthy addition to Sanyo’s catalog of ultra-low temperature freezers, cryogenic freezers, pharmaceutical and medical refrigerators, cell culture incubators, plant growth chambers, and portable autoclaves.
