DGJ-12F Corrosion-Resistant Manifold Freeze Dryer, -68 °C, 0.12 m² (CAT#: STEM-AL-4552-ZJF)

DGJ-12F Corrosion-Resistant Manifold Freeze Dryer, -68 °C, 0.12 m² is designed for freeze-drying samples that require a corrosion-resistant vacuum path and manifold operation. The system freezes the loaded material and removes ice by sublimation under reduced pressure. The documented cold-trap limit is ≤ -68 °C. The available drying area is 0.12 m² plus 10 manifold positions. The documented vacuum target is 5 Pa. The documented water or ice capture capacity is 6 kg. The loading arrangement uses 4 shelves. 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.
