Lyophilization of a Vacuum Freeze Drying Machine was used to prepare tissue samples for structural studies (eg, electron microscopy studies). Freeze drying is also used in chemical analysis to obtain dried samples or to concentrate samples to increase analytical sensitivity. Freeze-drying stabilizes the sample components without changing the chemical composition, making it an ideal analytical aid. Freeze drying can occur naturally. In the natural case, this process is slow and unpredictable. Through the freeze-drying system, people have improved and subdivided many steps to speed up the process.
Bell-type Vacuum Freeze Dryer: The freeze-drying alcove and the algid allurement are top and lower structures, and the freeze-drying alcove has no pre-freezing function. This blazon of lyophilizer requires chiral operation if it is transferred to the dehydration action afterwards the actual has been pre-frozen. Most of the beginning Benumb Dry Apparatus are bell-type, with a simple anatomy and low cost. Most of the freeze-drying accommodation use a cellophane plexiglass awning to facilitate the ascertainment of the lyophilization of the material.
In-situ freeze-drying apparatus exhaustion freeze-drying machine: the freeze-drying alcove and the algid allurement are two absolute chambers, and the shelf in the freeze-drying alcove has a cooling function. Afterwards the actual is placed in the freeze-drying chamber, the actual is pre-frozen and dried. The action does not crave chiral operation. This blazon of benumb dryer has a complicated accomplishment action and top accomplishment cost, but the in-situ benumb dryer is the development administration of the benumb dryer, an ideal best for lyophilization process, abnormally acceptable for medicine, biological articles and added appropriate products.
Ordinary shelf blazon exhaustion freeze-drying machine: The actual is bulk-packed in the actual tray and is acceptable for lyophilization of food, Chinese herbal anesthetic and crumb materials.
Vacuum lyophilizer with gland type device: suitable for drying of bottled materials. When lyophilized, prepare the materials in the vials as needed, float and cover the caps, freeze-dry them, and operate the gland mechanism after drying. The bottle cap can be pressed to avoid secondary pollution, re-adsorb moisture, and easy to store for a long time.
