Santrifüjler, or centrifuges, are devices used to separate substances of different densities by spinning them at high speeds. This process creates a strong centrifugal force that pushes denser materials outward, allowing for the separation of liquids, solids, or gases. They are commonly used in laboratories, medical facilities, and industrial applications. In a laboratory setting, santrifüjler can be used to separate blood components, such as plasma and red blood cells, for diagnostic purposes. In industrial applications, they help in the separation of liquids from solids in processes like wastewater treatment or the production of biofuels.
