Reliable, compact and quiet: these cold boxes are designed as desktop appliances and can be set up directly in the user's working area. These compact cold boxes thus enable decentralized storage of the chilled items. Transport to the external cold box appliance as well as cooling of the chilled items during transport is no longer required. Even if only small amounts of samples require freezing, the cold boxes offer a cost-effective and environmentally-friendly alternative.

The specialist for small-scale cooling in industrial and laboratory environments. Desktop appliance with a data logger and comprehensive monitoring options.
