Centrifuge Tube and Bottle

A centrifuge is a laboratory equipment used for the separation of heterogeneous mixtures or samples. It is driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity. Laboratory centrifuges work based on the sedimentation principle, where the centripetal acceleration is used to separate substances of greater and lesser density. Centrifuge tubes are used to contain liquids during centrifugation, which separates the sample into its components by rapidly rotating it around a fixed axis. Most centrifuge tubes have conical bottoms, which help collect any solid or heavier parts of the sample being centrifuged.
