DGJ-20E In-Situ Pilot Freeze Dryer, -70 °C, 0.20 m² (CAT#: STEM-AL-4581-ZJF)

DGJ-20E In-Situ Pilot Freeze Dryer, -70 °C, 0.20 m² is designed for in-situ freeze-drying process development and small pilot batches. The system freezes the loaded material and removes ice by sublimation under reduced pressure. The documented cold-trap limit is ≤ -70 °C. The available drying area is 0.20 m². The documented vacuum target is ≤5 Pa. The documented water or ice capture capacity is 8 kg. The loading arrangement uses 2 + 1 radiant shelf. Electronic control records operating parameters and supports process review through stored curves or exported data where specified. The system supports repeatable freeze-drying within the documented temperature, vacuum, load, and environmental limits.
