Centrifuge Rotor Types: Swinging Bucket vs. Fixed Angle

Centrifugation is one of the most widely used laboratory techniques for the separation of materials in the fields of biochemistry, molecular biology, medicine, food sciences and industry. It’s all about gravity and mass: particles in a heterogeneous solution will, given enough time, separate based on their size and density. Smaller, less-dense particles may also migrate down, but not always; some particles will never settle, but remain suspended in solution. Centrifuges force this process along much more quickly and efficiently. Its uses have proven to be so powerful and wide-spread across the sciences that centrifuges have been a common piece of laboratory equipment since the late 19th century.
