Vertical Freeze Dryer 0.12m² Stoppering (CAT#: STEM-LT-0603-ZJF)

This vertical freeze dryer series utilizes sublimation drying to remove water from pre-frozen samples under vacuum conditions. The process preserves the original physical, chemical, and biological characteristics of the sample. The dried product is stable for long-term storage and can be restored to its original state when rehydrated. With flexible configurations including stoppering and manifold models, it is well-suited for laboratory applications in food technology, pharmaceuticals, and biotechnology.
