Freezing and drying process of LGJ-100F (silicon oil heating) are finished in the same place (patented product). It changes the cumbersome operation of the drying process in the past, prevents the contamination of materials, and realized dry sublimation automatically. The model is equipped with shelf heating and has programmable functions. It can memorize freeze-dried curves for users to observe the lyophilization process of materials.ã?? ã?? 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.
