In the world of scientific research, time is often the biggest enemy. Many biological samples, drugs, foods, and even chemical reagents can undergo changes over time, affecting experimental results and even leading to the loss of valuable samples. However, the existence of desktop freeze dryers has given scientists the ability to "freeze time", allowing samples to be stored for a long time without losing their activity.
What is a desktop freeze dryer?
Shanghai Yetuo desktop freeze dryer, as the name suggests, is a small equipment that uses freeze-drying (Lyophilization) technology. Its working principle is based on sublimation, which means that water changes directly from solid (ice) to gaseous (water vapor), skipping the stage of liquid water. This process usually consists of three steps:
Pre freezing stage: Cool the sample to ultra-low temperature (usually below -40 ℃) to freeze the moisture in it.
One drying stage: In a vacuum environment, ice is directly sublimated into water vapor by heating and discharged from the sample.
Secondary drying stage: Continue heating to remove residual moisture and achieve the desired drying state of the sample.
Why can't the laboratory do without it?
In the field of scientific research, the Shanghai Yetuo desktop freeze dryer has a wide range of applications, involving almost all biomedical and chemical research. Here are several main application areas:
Biological sample preservation: Fine Jun, viruses, enzymes, serum, proteins and other biological samples can be preserved for a long time after freeze-drying, and their activity can be quickly restored after adding water.
Pharmaceutical industry: Many vaccines and antibiotics require cold chain transportation, but through freeze-drying treatment, they can be stored at room temperature for longer periods of time, improving the convenience of transportation and storage. For example, penicillin and some anti AI drugs use freeze-drying technology.
Food processing: Freeze dried strawberries, freeze-dried coffee, and even space food are all made using this technology. It not only maintains the nutrition and flavor of food, but also significantly extends its shelf life.
Archaeology and cultural relic protection: Some ancient papers, books, or biological fossils can also be repaired and preserved through freeze-drying technology to avoid damage caused by moisture or microbial erosion.
The Future Development of Shanghai Yetuo Desktop Freeze Drying Machine
With the advancement of technology, Shanghai Yetuo desktop freeze-drying machines are becoming more intelligent. Some new devices can monitor the drying process in real time, control temperature and vacuum degree, and even optimize freeze-drying solutions through AI. In the future, individuals and families may also be able to use small freeze-drying machines to make freeze-dried food at home, and even preserve pets' DNA to preserve beautiful memories.
Although desktop freeze dryers are compact in size, they are essential tools for scientific research, pharmaceuticals, and even the food industry. It is like a 'time wizard', keeping samples in their original state over time and driving technology and life forward.
