A unique design compared to any other deep freezer in the -40°C class, the DF series are produced according to the standards of a -86°C ultralow temperature freezer. Moreover, the NÜVE design is exceptional with the cooling coils inside the shelves to provide the most efficient heat extraction. DirectFREEZE™ ensures the greatest possible protection for your samples.

Optimized for cryotube storage, the storage accessories for the FR series also include shallow, medium and deep drawers for samples such as plasma bags and other, irregularly-shaped packs. A custom manufacturing service ensures that you can always retrieve your samples in a convenient way. The special design of the handle means that you can always access the chamber, even immediately after closing.
