Freeze dryers and lyophilizers for your production

Single chamber systems for efficient and cost-effective freeze drying

Sublimator EKS series – The professional entry into freeze drying. The single-chamber freeze dryers of this series are particularly suitable for drying liquids, such as milk, collagen gel or similar. The ice condenser is located directly behind the shelves in the same chamber and is perfectly matched in terms of shelf size. The trays are placed directly on the footprint for drying. The thermal energy is transferred via direct “contact”. This is why it is called contact drying. The special feature of these shelves is that a brine oil flows through them for temperature control. In addition to particularly precise control, this also permits freezing and heating of the footprint. In this way, complex temperature protocols can be defined and reproducibly run. In addition to the standard freeze dryers listed below, we have already realized other special sizes. Please do not hesitate to contact us!

Special design as two-chamber system “DKS

For special applications, it may be advantageous to be able to perform a pressure rise test. For this purpose, the ice condenser must be mechanically separated from the drying chamber in order to briefly interrupt the freeze drying process. This is done with a separating valve between the freeze drying chamber and the ice condenser. As soon as this valve is closed, the pressure rise in the drying chamber can be measured. The pressure rise in the drying chamber can be used to determine the extent to which drying has been completed. The parameters can be set in the operating menu. The process is fully automatic. This special version of the freeze dryer is available from the Sublimator 100 upwards and is then called, for example, Sublimator 100 DKS.
