ZLGJ-12 Lab Freeze Dryer

Freeze Drying Principle

Freeze drying is the process of removing water or other solvents from frozen biological products by sublimation. Sublimation refers to the process by which a solvent, such as water, like dry ice, changes directly from a solid state to a gaseous state without going through a liquid state. The product obtained by freeze-drying is called lyophilizer, and the process is called lyophilization.

What is lab freeze dryer?

Laboratory freeze dryers are mostly used in universities and laboratories. Compared with ordinary freeze dryers, the main features are small size, flexibility and lightness, which is convenient for freeze-drying experiments of various materials and medicines.

Freeze-drying Technology Advantages

1. Freeze drying is carried out at low temperature, so it is especially suitable for many heat-sensitive substances. Such as proteins, microorganisms and the like will not denature or lose biological activity.
2. When drying at low temperature, the loss of some volatile components in the substance is very small, which is suitable for drying some chemical products, medicines and food.
3. During the freeze-drying process, the growth of microorganisms and the action of enzymes cannot be carried out, so the original characters can be maintained.
4. Because the drying is carried out in the frozen state, the volume is almost unchanged, the original structure is maintained, and the phenomenon of concentration will not occur.
5. The dried substance dissolves rapidly and completely after adding water, and restores its original properties almost immediately.
6. The substances that are easily oxidized are protected.
