Centrifuge

A centrifuge is a piece of equipment that puts a substance in circular motion in order for the centrifugal force to separate a fluid from a fluid or from a solid substance. Generally, a motor drives the rotary motion of the sample. There are many different kinds of centrifuges, often for very specialised purposes.

The ultracentrifuge is a device invented in 1925 by Theodor Svedberg, which by use of very high acceleration, and allowing the observation of sedimentation rates for macromolecules, allowed for the determination of their approximate

Ultracentrifuge: The ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1,000,000 G (9,800 km/s²) There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge. The second, however, is more theoretically...

1925: 1925 was a common year starting on Thursday (link will take you to calendar)....

Theodor Svedberg: Theodor (The) Svedberg (August 30, 1884 – February 25, 1971) was a Swedish chemist and Nobel laureate. His work with colloids supported the theories of Brownian motion put forward by Einstein and the Polish physicist Marian Smoluchowski. During this work, he developed the technique of analytic...
