LGJ-18 Top Press Type Experimental Freeze Dryer   Applications
　　This model is not only suitable for the freeze drying of bulk (liquid, pasty, solid) conventional materials, but also suitable for the drying of the vials materials. When the materials are ready for freeze-drying, they are put into in the vial, then begin freeze drying before the vial's lid unsealed. The capping device compacts the vials' lids after freeze drying to prevent secondary pollution, re-adsorb water, and facilitate long-term storage.
