KD-10N series laboratory freeze dryer, compact structure, rich functions, easy operation, intelligent storage, data management and other functions
A: The laboratory freeze dryer is small in size, light in weight, multi-functional, stable in performance, high in test system accuracy, and multi-purpose in one machine, which can adapt to freeze-drying experiments of various materials. Laboratory freeze dryers can be divided into the following categories:
a: Cover type freeze-drying machine: the freeze-drying chamber and the cold trap are separate upper and lower structures, and the freeze-drying chamber has no pre-freezing function. This type of lyophilizer requires manual operation when it is transferred to the drying process after the material has been pre-frozen. Most of the experimental freeze dryers are bell-type, which has a simple structure and low cost. Most of the freeze-drying chambers use a transparent plexiglass cover to facilitate the observation of the lyophilization of the material.
b: position type freeze-drying machine: the freeze-drying chamber and the cold trap are two independent cavities, and the shelf in the freeze-drying chamber has a cooling function. After the material is placed in the freeze-drying chamber, the pre-freezing and drying process of the material does not require manual operating. This type of freeze dryer has a complicated manufacturing process and high manufacturing cost, but the in-situ freeze dryer is the development direction of the freeze dryer, and is an ideal choice for lyophilization process, especially suitable for medicine, biological products and other special products. Freeze dried.
Second, from the function
a: Through shelf type: The material is bulk in the material tray and is suitable for lyophilization of food, Chinese herbal medicine and powder materials.
b: gland type: suitable for the drying of the bottled material of Xilin. When preparing for lyophilization, the material is packed into the vial as needed, floated and capped, and then freeze-dried. After drying, the capping mechanism is pressed to compact the bottle. The cover can avoid secondary pollution, re-adsorb moisture, and is easy to store for a long time.
c: manifold type: 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, and the mixture is passed through The manifold switch unit can be removed or loaded at any time as needed without downtime.
d: Freeze function type: material pre-freezing process, the cold trap is used as pre-freezing material in the pre-freezing chamber. During the drying process, the cold trap is a water trap to capture the water overflowing from the material. The lyophilizer with pre-freezing function, the pre-freezing and drying of the materials in the freeze-drying process are all completed on the lyophilizer, and the lyophilizer has high use efficiency, which saves the cost of the low-temperature refrigerator.
