Model	Application difference
NBJ-12 Standard type	Suitable for freeze drying of conventional materials in bulk (liquid, paste, solid)
NBJ-12 Top-press type	It is not only suitable for the freeze-drying of conventional materials in bulk (liquid, paste, solid), but also suitable for the drying of the bottled materials of vial. When preparing for lyophilization, the materials are dispensed into the vials as needed, and the caps are floated and frozen. Drying, after the end of drying, the capping device is pressed tightly to avoid secondary pollution, re-adsorb moisture, and easy to store for a long time.
NBJ-12 Standard manifold	It is suitable for freeze-drying of bulk (liquid, paste, solid) conventional materials, and can be used to pick up the flask outside the drying chamber to dry the material that is frozen on the inner wall of the bottle. At this time, the flask is used as a container to be connected to the outside of the drying oven. On the tube, the material in the flask is heated at room temperature, and the multi-manifold switch device can be used to remove or load the flask as needed without stopping.
NBJ-12 Top-press manifold	On the basis of the common type characteristics, it combines the characteristics of the gland type and the multi-tube type. · Suitable for freeze drying of conventional materials in bulk (liquid, paste, solid); ·It is suitable for the drying of the bottled materials of Xilin. When preparing for lyophilization, the materials are packed into the vials as needed. After the caps are floated, the caps are freeze-dried. After the drying, the capping device is pressed to tighten the caps. Contamination, re-adsorption of water, easy to preserve for a long time; ·The flask is attached to the outside of the drying chamber, and the material frozen on the inner wall of the bottle is dried. At this time, the flask is connected as a container to the manifold outside the drying box, and the material in the flask is heated at room temperature through a multi-manifold switch device. The flask can be removed or loaded at any time as needed without downtime.
