A plasma separator is a medical device used to separate plasma from blood. Plasma is the liquid component of blood that carries cells, nutrients, and waste products. The separation process typically involves centrifugation, where blood is spun at high speeds to separate its components based on density. This device is essential in various medical applications, including blood donation and transfusion. By isolating plasma, healthcare providers can create treatments for conditions like hemophilia and immune disorders. Plasma separators help ensure that patients receive the specific components they need for effective treatment.
