High-speed centrifugation is an irreplaceable tool for the isolation and characterization of multiple biological structures: from biomolecules, such as nucleic acids and proteins, to cell organelles and viruses.
A centrifuge is a machine that spins a sample at high speed, in order to generate a force –called centrifugal force– that separates the components of said sample, in order to analyze them. It is applicable to biology, pharmaceuticals, chemistry, among others.
It is an extremely useful piece of equipment for many types of clinical and research trials.
Different types of centrifuges accommodate different types of centrifugation: preparative centrifugation, which aims to isolate specific particles, and analytical centrifugation, with which physical properties such as sedimentation rate or molecular weight can be estimated.
