The chamber of the DF series is designed around the sizes of the most commonly used cryoboxes that account for over 80% of all usage. This means that the maximum numbers of samples are stored in the minimum footprint.

The DF series Ultra Low Temperature Freezers are powered by N-SmArt™ which has internal memory storing temperatures records up to ten years with one hour intervals as digitally and graphically. By means of NuveCloser™ software, The DF series can be controlled via internet. Sample safety is given top priority with audible and visual alarm system and optional NuveWarn™ remote alarm system, plus an optional AlerText™ text message to multiple mobile phones.
