How was vacuum technology used to prepare blood plasma?

Vacuum technology is essential for processes that require conditions below normal atmospheric pressure, such as removing volatile liquids or gases from materials.1

In the context of medical science, vacuum technology was utilized to facilitate the preparation of blood plasma for blood banks. This process relies on the principle of disturbing equilibrium conditions to remove volatile components from a substance, a technique similar to freeze-drying. By performing these operations in a vacuum, researchers and medical professionals were able to achieve results that were unattainable under normal atmospheric conditions, ensuring the stability and preservation of the plasma for clinical use.1
