Filtration
Filtration is a fundamental process in biotechnology where scientists separate different materials, like removing unwanted particles from valuable biological products. Think of it like a very advanced coffee filter, but for pharmaceutical drugs, vaccines, or other biological materials. Companies use various types of filtration methods depending on what they're trying to separate - from simple particle removal to complex protein purification. This is a crucial step in making sure biological products are pure and safe for use.
