DGJ-12SL Manifold Vacuum Freeze Dryer, -90 °C, 0.12 m² (CAT#: STEM-AL-4546-ZJF)

DGJ-12SL Manifold Vacuum Freeze Dryer, -90 °C, 0.12 m² is designed for laboratory freeze-drying of tray samples and manifold flasks. The system freezes the loaded material and removes ice by sublimation under reduced pressure. The documented cold-trap limit is ≤ -90 °C. The available drying area is 0.12 m². The documented vacuum target is 5 Pa. The documented water or ice capture capacity is 6 kg. The source describes controlled shelves or trays for sample loading. 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.
