Medical lyophilizer

The lyophilizer is suitable for heat sensitive and heat variable denatured substances. Such as biological field: drugs, vaccines, serum, plasma, antibodies, microorganisms, plant extracts and so on. Non-biological fields: food, nanoparticles, colloids, plants, cultural relics, etc.

1.The medicine is packed separately before freezing, and the dosage is accurate.

2, drying at low temperature, can make the heat sensitive substances in the dried drugs remain.

3. Drying under low pressure, the dried drugs are not easy to oxidize and deteriorate, and can be sterilized or inhibit the activity of some bacteria due to hypoxia.

4. When frozen, the dried drug can form a "skeleton", which can keep its original shape after drying, forming a porous structure and basically unchanged in color.

5, good water rehydration, freeze-dried drugs can be rapidly reduced to the state before freeze-drying.

6. Dehydration thoroughly, suitable for long-distance transportation and long-term storage.

Freezing vacuum drying is a commonly used drying method of pharmaceutical preparation, called freeze-drying for short. Lyophilization refers to the process of removing water by sublimating liquid medicine from solid state to gas state without passing through liquid state directly after frozen into ice.

The process consists of three independent but interdependent steps: freezing, primary drying (sublimation), and secondary drying (desorption).

The advantages of the freeze-drying process are as follows: 1) convenient liquid processing; Simplifies the aseptic process; (2) improve the stability of dry powder; (3) can remove the moisture in the product without heat treatment; (4) Enhance the stability and rehydration (solubility) of freeze-dried products.
