NUVE DF 290/490/590 -86°C Ultra Low Freezers
The ultimate protection for your samples is ensured by placing the cooling coils inside the shelves to provide the most efficient heat extraction. No reliance on air convection to transfer energy to the walls of the freezer but transfer by conduction with DirectFREEZE™.
- Three different sizes: 261, 461, 560 liters.
- Powerful and reliable N-Smart™ microprocessor control system
- Maximum information with highly visible 4,3’’ colorful LCD display.
- Ethernet port for remote access through internet
- Possibility of sending e-mails in case of any failure
When the DF series are used according to instructions, occasionally wiping away the ‘snow’, no ice will form on the door, maintaining efficient cooling.
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.
