How a Centrifuge Works - Drucker Diagnostics

A centrifuge is a machine that uses centrifugal force to separate the contents of a sample based on their density. When the centrifuge spins, it creates a strong centrifugal force. Though separation would eventually happen naturally with Earth’s gravity, the centrifuge machine delivers rapid results for laboratory and other appliions.
