A standard ultracentrifuge by manufacturer Beckman Coulter. An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1] There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.
Beckman Coulter, Inc. is a Danaher Corporation company that develops, manufactures, and markets products relevant to biomedical testing. It operates in the industries of diagnostics and life sciences .
Arnold Orville Beckman (April 10, 1900 – May 18, 2004) was an American chemist, inventor, investor, and philanthropist. While a professor at California Institute of Technology, he founded Beckman Instruments based on his 1934 invention of the pH meter, a device for measuring acidity (and alkalinity), later considered to have "revolutionized the study of chemistry and biology".

A laboratory centrifuge is a piece of laboratory equipment, 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.
Beckman Coulter (now Danaher) has previously manufactured chain termination and capillary electrophoresis-based DNA sequencers under the model name CEQ, including the CEQ 8000. [27] The company now produces the GeXP Genetic Analysis System, which uses dye terminator sequencing . [ 28 ]

Benchtop fixed-angle centrifuge, or swinging bucket centrifuge Intact (eukaryotic) cells, macroscopic debris Varies depending on sample Gently lysed cells (e.g. dounce homogenizer) 600 x g 10 min Benchtop fixed-angle centrifuge, or swinging bucket centrifuge Nuclei Cytosol, non-nuclei organelles Supernatant of previous row 15,000 x g 20 min
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
