For applications in the field of research and development, as well as small-scale production
Freeze dryers of this series are designed for the laboratory or product development. Depending on the size of the unit, the free-standing units have an ice capacity of 5 to 40 kg and a footprint of up to 2.7 m². These units are equipped as standard with a vacuum valve for regulating the vacuum and a separating valve between the drying chamber and the condenser. In relation to the footprint, these units are characterised by a compact design. The cladding is made entirely of stainless steel and is therefore resistant to all commercially available disinfectants.
