How to choose a laboratory freeze dryer

As a common refrigeration equipment in laboratories, the utilization rate of freeze dryers is very high. In many important experiments, freeze dryers play an essential role in pretreatment. The drying process of the freeze dryer is a complex and delicate process, which is mainly divided into three stages: pre-freezing, primary sublimation drying and secondary desorption drying.

How to choose laboratory freeze dryer:

1. The selection of freeze dryer should be based on specific needs. If the simple and convenient operation is required and there are not many requirements for parameter adjustment, then you can choose a desktop freeze dryer with a two-in-one cold trap shelf and an external freeze-drying bottle. The 2.5L desktop freeze dryer is a classic and is used by many laboratories.

2. If you have certain requirements for parameter adjustment, you need to choose a research and development freeze dryer that can set the vacuum degree, partition heating program, and add a temperature-sensitive probe. R&D freeze dryers are generally larger in scale than desktop freeze dryers only used in laboratories.

3. In general, if you simply concentrate the sample, remove the water, and freeze-dry it for storage, a simple desktop one can meet the needs. If you want to develop a freeze-drying process and explore freeze-drying curves, you need a research and development freeze-drying machine.

As an important equipment in modern industry, vacuum freeze dryer has a wide range of applications, involving pharmaceutical, food, biotechnology and other fields. Choosing the right freeze dryer can not only improve production efficiency, but also ensure product quality and safety.
