A laboratory centrifuge is a device used to separate components of liquids. It is usually used for the separation of biological samples, blood, cells or DNA. A centrifuge separates components based on density differences by spinning the sample very quickly. This allows, for example, the separation of blood into plasma, red blood cells and white blood cells. Some basic features of centrifuges are: Rotation speed (RPM): The faster it spins, the more effective the separation. Rotor type: Different types of rotors are used, and adjustments are made according to the tube capacity and the type of process used. Closed/open system: Closed systems are generally more suitable for sterile environment requirements.
